Hardware :: USB Mouse And USB DAC Can't Be Used Simultaneously?
Mar 26, 2010
I have a USB mouse and a USB audio DAC. Both work fine separately with linux. The problem is when I try using both simultaneously. The first-plugged device will work fine, but not the second-plugged device. That is, if I plug the mouse first and the DAC second, then the mouse works and the DAC doesn't work. And conversely.
When I say that the second-plugged device doesn't work, here's what I mean: the USB device is detected by the system, but gets "reset" every 2 seconds and can't be actually used at all. Here are some log messages. Here I'm working in the case where I have plugged the mouse first and am plugging the DAC second.
Code:
$ lsusb | egrep -i mouse|texas
Bus 002 Device 009: ID 08bb:2704 Texas Instruments Japan
Bus 002 Device 007: ID 046d:c526 Logitech, Inc. MX Revolution Cordless Mouse
"Texas Instruments" is my DAC. So, at the level of lsusb, all is well.
Sun VBox host - Debian 5.0 VM - Ubuntu 10.04 (lucid) gnome desktop rdesktop
Running rdesktop to connect the VM on the host connection can be established with VM desktop displayed on the host desktop. But there are 2 mouse pointers on VM desktop. It is difficult to control. One mouse pointer does not work but hanging there. 2 pointers moves simultaneously.
I am currently using gnome on Fedora 11 and English is the default language on the system. I was able to figure out how to make it possible to add Spanish characters when I type (likeetcetera). I also figured out how to install Spanish dictionaries for the software I use that commonly does spell checking. how to have two default dictionaries in use at the same time. For example if I am using OpenOffice to write something, I would like to be able to write in either Spanish or English and not have worry about changing the dictionary in use. Is it possible to have two dictionaries set up at the same time?
is it possible to use two dvd burners simultaneously to burn an image ? Reason i ask,i have two dvd burners & wish to utilize both at the same time,so i can burn multiple dvd's for the school i work at.If it's possible, how & what software do i use ?
I have two networks on a server. One being my internal network, and the other being an external IP address. This is on Debian Lenny. Here is my /etc/network/interfaces file:
I can reboot my system and sometimes eth1 is accessible from SSH, and other times eth0 is accessible. Then sometimes eth1 will just stop being pingable alltogether. This is a fairly fresh install of Debian, and the only thing I have running is VMWare Server 2.0, bridged to both of my network connections.
I'm tring to download an iso image that's over 3GB. The file is hosted at several ftp mirrors. Is there a way to download the file from several of these mirrors simultaneously so that I can reduce the D/L time? Presently, it's will take close to 24hrs to D/L from just one mirror. I have a 25Mbps connection so my bandwidth is not an issue.
I want to copy data from one source drive to three or more destination drive simultaneously. I tried with dd command. But it copy entire Hard disk. Its take long time to copy entire disk. i need the utility or software to copy one source to multi destination simultaneously and fast manner
I have two ISP Connections from different Providers BSNL and Sify. Both are 1MBps. In my Office Now we are using Sify for Only one Machine and BSNL is configured in wifi router. But Often BSNL network is in problem. So we have planned to use both Sify and BSNL simultaneously. what we have to do is to Make some arrangements either in cabling or in configuring we have to use both the connections simultaneously. without hassle so that the employees will always be on-line. and they may not know in which ISP they are browsing. But the internet should be available always.
We have two servers which has running Redhat 5.5 with two Onboard Ethernet card so totally Four Ethernet cards. And we are using Only linux such as fedora, ubuntu and CentOS in our Office and not windows. And all are connecting to internet by wireless. So please give some ideas to use any linux machine as router or something else that would balance the two ISPs equally, that is if one ISP is down then the other should take up automatically without doing any manual configuration and without buying any proprietary software or any hardware.
I want to use the two huawei 3G modem card simultaneously.Now by using pppd,I can got the PPP connection separately.but when I did them simultaneously,only one can successfully establish the ppp connection，the other will be blocked.If i kill the pppd process which already establish the ppp connection，the blocked one could then connect to the ISP and establish a ppp connection successfully. If I want to use them simultaneously,how should I do.I think maybe my linux only support only one pppinterface
I'm looking for a way to use klogd and/or syslogd to log all the default message levels to the standard /var/log/messages. I also want all kernel (and possibly user) error messages to also be logged to a second file. Is this even possible?
what i want to do is run two commands (nautilus and gedit) from the command line/shell script at the same time. i can obviously do && between them, but this requires the first app to close before moving on to the second one. i want to run both apps at the same time so i can run gedit with some project files open on it, and nautilus to browse those files/other files.
It's easy to have multiple user accounts on one computer and even switch between accounts without logging off. It is also possible to have more than one display connected to a single computer. Is it possible to have one multi-core computer be used simultaneously by two users in their own accounts? Is there specific hardware required (to allow keyboard and mouse distinction for each user) and software configuration?
I know you can setup remote connections on windows that allow you to open and use a second user account without bothering the first user, but how about working locally on the same machine, essentially removing the network delay of remote desktops? What OS supports this? Linux Ubuntu? Windows 7?
I made a script for batch processing brain scans (with FreeSurfer). I have a batch file stored on an NFS server that looks something like this:
Code:
subject1 subject2 subject3 subject4
now my script is performed on several computers at a time, first it marks an item to be in use (with sed -i 's/.../...'), then processes it (it gets the actual subject files from elsewhere on the server, then puts them back), then marks it to be finished in the list. so during action the batch file should look something like this:
Code:
subject1 finished subject2 inprogress on host1 subject3 inprogress on host2 subject4
so i tried a run and watched the batch file, now i observed something like this:
Code:
subject1 finished subject2 inprogress on host1 subject3 inprogress on host2
[code]....
there was only one script running on host1. the subjects never got marked as finished, although i know for a fact that they were finished. also, the script sometimes seemed to hang for moments.
I started a new x session on tty8. This is display 1. The first session is tty7 display 0.
I can switch between them easily enough. CTRL ALT F7 goes to tty7. CTRL ALT F8 goes to tty8.
But if I try to run, say, the "import" command for screenshots on tty8, while switched to tty7, all it gives is a black screen.
The reason being, I think, because only one session is actually outputting at any given time. How do I make both of them output, so I can take a screenshot on 1 session, but use the other session to do other stuff?
I recently purchased a set of three professional mics and converters for them (they are XLR mics, so i bought three icicles to convert into the USB port)The computer sees all three microphones, but I can figure out how to be able to record on all three at the same time.Is this at all possible, or did I just waste a ton of money on converters?EDIT: I would like to add that these mics are identical, and I'm wondering if nothing else if it's possible to merge the two mount points so that it appears as one micEDIT AGAIN: I have also just installed Pulse Audio Volume Control, and it picks up both mics. How can i tell audacity to use this?
I'm planning on getting an HDTV soon, and I'd like to be able to hook it up to my computer so that I can watch movies on it through my computer. I don't want to have dual monitors in the traditional sense where my desktop is spread across two screens. Rather, I just want my desktop to appear exactly the same on both my monitor and TV.
Is this possible? And if so, what would be the best way to go about doing this? My video card has two DVI ports, so I was planning on running a cable from the unused port to my TV and using a DVI-VGA adapter. Or would I be better off getting a TV with an S-video port, which I also have on my card, and connecting it that way
Where I work we use almost exclusively Ubuntu 8.04 in command-line only form. I need to know if it is possible to configure one of these devices to use DHCP and a given Static IP at the same time. I know how to do one, or the other, but not both. #1. Is this possible? #2. If so, how?P.S. Yes, I did look around before I asked this, but I could not find anything. Maybe I suck at searching?
I have a Lucid server with several external (eSATA) NTFS formatted drives. Right now, I'm sharing everything through Samba and administered through Webmin. Partly because I'd like to play with it and learn more and partly to see if there's any appreciable difference in overhead and speed, I'd like to try out NFS.
My question is, can the two sharing schemes (NFS and Samba) coexist on the same box peacefully?If not, I can rid of Samba and go with NFS, but I'd rather give it a shot first.Plus, some of the clients are Windows machines, so I'd have to install the SFU tools in order to get an NFS client on them.
I'm on Ubuntu 10.04 64bit, and I've got JACK and Pulseaudio both installed, though I don't run them simultaneously. I also have LinuxSampler and Rosegarden, and I have the necessary ALSA drivers. Pulseaudio can output to my external sound card, but JACK doesn't, even if I tell it to. I've seen its full name (Guitar Rig Mobile IO) and chosen it as the output device under Settings, but to no avail. It still sends the output to the internal (and crappy) sound card.
my internal sound card is used for videos and normal movie watching. second sound card m-audio connected to amplifier and speaker which is in living room. most of the time i need to use these sound card simultaneously. i want second sound card to be used with banshee or rhythom box to listen audio and keep the internal sound card for any other default audio usage
I am interested in sharing an external drive between two computers. I do not want to disconnect the drive from one and then connect it on the other one - I want to share it.
Would this work with an external USB drive and a normal USB hub? Or is it something more complicated/impossible?
Also connecting the machines via network is not possible - it has to be USB, or I can connect it to one machine also via Ethernet but the second connection has to be USB.
My current computer has a VGA output on the motherboard and I'm interested in adding a monitor. I have a separate nVidia card which, when installed, seems to default as the primary. Is there any way to have the system use both the VGA on the motherboard and the additional video card? I've seen a lot of suggestions to modify xorg.conf but the file is nowhere to be found on my machine.
In my code I want to have two different functions to be executed simultaneously (in parallel) in a single processor system. I tried to use pthreads but they happened to be executed one after another. I have heard about fork, some saying that its no longer recommended since its functions can be achieved by pthreads.
Doing my final year project in linux- a Mozilla Firefox extension which providing chat option for two or more peoples,who happen to be browsing the same website simultaneously. It shows you other people who visit the same websites as you are. These people have to be registered with our software. I don't know how to go about this. After a lot of googling and enquiring i have divided the project into three modules: an extension at browser side, chat implementation (probably in ajax) and a server- apache-php-mysql.
The extension keeps track of the URLs visited by the browser. It sends this information to the server. When it receives information from the server, the extension displays the number of users visiting the URL as the user. The extension informs the server whenever the user clicks the EnableChat(which will be embedded in a toolbar in the browser) button to start a chat session. After receiving the information, the extension displays the users in that site. The user clicks on a particular username for chat.
I have installed php mysql and apache. but i do not know exactly what the server must do. I know i have to write the server code in php and put it in the /var/www folder. but what should that code do? how exactly does the extension or browser communicate with the server for the exchange of above info?
I have been working on a project for a while now that involves a rather complex daemon that has to be simultaneously running different tasks. For example one of these tasks is to receive IP packets from the Netfilter queue and place those packets into one of several internal queues. While other tasks involve taking IP packets from those internal queues and processing/manipulating them and finally returning them back to the Linux network stack.
As I as I have no previous C experience before starting this project I just spawned a new thread each time I needed the daemon to be doing something else while those other tasks continued to run. Is there any other way of doing this or is this pretty much the only way of doing this? Because C is procedural I could not figure out any other way of doing accomplishing what I wanted. Should I have done it some other way or is this the correct and only way I could have gotten my C app to be running multiple tasks at the same time?
