Ubuntu :: Can't Connect Different Usb Devices To The Same Usb Ports If A Device Had Been Previously Connected To It
Nov 1, 2010
I am running 9.10 latest updates (as far as I know) My problem is with my usb connections.I cant connect different usb devices to the same usb ports if a device had been previously connected to it. IE: I have to keep my camera connected to one particular port. If I disconnect it and connect anything to it, it cant be seen. It doesnt matter if I reboot. Is there a way to clear out any memory that stores the usb port assignments?

How do you determine the source and version of a device driver in your linux box? (The wifi driver, for instance.) In windows you can find that info using "device manager". I suppose there is some corresponding tool in linux.

I have a box with 6 Ethernet ports. One is the main connection to the box, and the remaining are for connecting to one host each (1-1, ie, 5 different boxes connected to each of 5 ports on the box). I setup a static route to each of the hosts, and it worked. But, now it just doesn't work. There are no firewalls, etc.
Box_A: 10.2.1.200 (going to the switch to outside).It has 5 other ports: port1 (10.2.1.11) <----> Host1: 10.2.1.20 port5 (10.2.1.15) <----> Host5: 10.2.1.25 If I do, ping -I eth1 10.2.1.20, from Box_A it doesn't work. But, it used to work.

I have Virtualbox installed from the Ubuntu repository. As I just found out, I can't access any USB connected devices (printer, scanner). It seems I can get these USB peripherals to work by using a different Virtualbox repository. how to do this without loosing the OS installation that I have already setup in Virtualbox?

Had this strange issue ....
Steps
a. Working Gnome desktop with NVidia proprietary drivers in Jessie.
b. Something happened (see below)
c. Still working Gnome desktop with NVidia proprietary drivers in Jessie.
d. Reboot
e. Boot up in low res -can see the terminal messages but no X/ Gnome Desktop
f. CtrlAlt-F1 takes to terminal login
g. Log in, looked at dmesg, syslog shows no errors but looking at Xorg.[0-5].log shows:
Code: Select all[Â Â Â 7.942] (II) NVIDIA(GPU-0): Found DRM driver nvidia-drm (20130102)

After looking at this post [URL] .... poked around at the back of the monitor and found the DVI cable loose. Plugged it in tight and rebooted and Gnome desktop came up as good as ever.
Step b. , as it turns out, was someone had adjusted the monitor height resulting in the DVI cable coming loose but not getting pulled out entirely.

This may be more suited for the networking forums, but I figured Community Cafe would be well rounded enough for someone to tell me if this is even possible (with minimal configuration that is).There are a few places I travel where I only have a wired connection to the Internet (no wifi), but when this happens is there a simple way to create an adhoc network so wireless devices can route through my computer and to the network? Reason I'm asking is I'm thinking of getting an iPad or iPod Touch which have wireless connections, but in the cases where my laptop is using a wired ethernet connection and the wireless card isn't used, I'd like to create an adhoc wireless network that'll let such wireless devices work.

I am running Lenny. USB storage devices are painfully slow, if the data to be copied is above 4GB it works on transferring for more than half an hour and then comes up with an error dialog(saying something like file size is too big). The problem exists in both read and write.
I did google a bit and here is the output of lsmod | grep hci
ehci_hcd28428 0
uhci_hcd18672 0

When I connect my Debian PC to my WiFi router my PC doesn't get internet if other devices are connected to it .
When i disconnect those devices and connect my Debian PC only then my PC connects to internet but other devices connected to it later do not get inernet connection.
When I connect my Debian PC using LAN Cable to the same router all devices work fine.

I've been playing with Ubuntu for a few years, and it runs great on said notebook, so I' m starting to ween myself from Windows.Biggest consideration for switch is music. I currently have an iPod touch 16. Been using itunes for a long time.I'm not married to the device or the software, and will rebuild my music library if needed (it's a pig of a mess anyway).I'm curious which mp3 device you are using and what linux software you are using it with for great results. I want a high end player iwth 16+ gig, and a music manager to keep a 10000+ file library organized. I frequently want to change the mix of albums on my device. I'm fine with buying music elsewhere from Apple. Prefer it actually - Amazon is a good choice.Should I keep hte iPod? Trade it for a Zune or something else? Sound quality is very important to me. As is wireless access/browsing, storage space, battery life, etc

I am trying to write a script to turn my HTPC off automatically and turn it back on again at a specified interval.
I've got the turn on off bit sorted using /sys/class/rtc/rtc0/wakealarm but I want the script to not turn the machine off if say something is downloading, I am currently watching something etc and i dont think I will have any trouble with that.
But what I would really like to be able to do is tell if my TV is currently on. I dont think anything x11 related would work here and this may not even be possible. Does Ubuntu "know" if it's display device is powered on or not? if so can I interrogate this somehow?

I got a sort of usb connected device(not an external enclosure) so i can connect a sata hard drive into a machine that only has ide connections but the drive is not mounting. I am not very good at mounting slave hard drives anyway ,,,,never been able to get one happening without help. I am wanting to read this drive as i killed another desktop machine(i think the mb) and i need the data off the hard drive. The drive is shown in a directory and in the media directory. Can't think of what else sorry as i am so tired from testing everything out of the machine that i killed.....

I'm running archlinux & just recently started having a problem where ALL USB devices will stop responding for a second when a new USB device is plugged in. dmesg doesn't provide any hints.For example, I've got my music on an external HD & it will stop playing for like ~30 seconds if plug in my camera or gamepad...This issue only seemed to start after my home partition was erased & re-created, though I don't see how these two issues could be related.I've been running a custom kernel (2.6.35-rc6) for the past few months, and that hadn't changed to spur this issue. Thinking it may have been something weird with the kernel, I even switched over 2.6.36-rc6-mainline, yet this did not remediate the issue.

I was wondering if there's any way for a laptop to be both simultaneously connected to a wireless network, while at the same time acting as an ad-hoc network with local access to serve as a wifi connection for my mobile device, which would be ssh-ing into the laptop and using local resources.

I need a bash script to run ARPON for the connected network device, eth1 or eth2. (ethernet or wireless)
Arpon has an option (-o) to select the network automatically, but it only works for ethernet, hence i need this script. I've also tried running arpon for ethernet and wireless at the same time, but the arpon process running the inactive device will consume all of my CPU.
So, basically i need a script to find which device is connected, eth1 or eth2 and then to run arpon -d -i <device connected> (or something like that).
Is there an easy way to do this? code...
I've searched everywhere how to find the connected device via bash, but i couldn't find anything.

When I scan the blue led comes on solid and goes back to blinking afterwords but nothing is found. I did try another adapter and the bluetooth worked. BTW The Bluedevel application is real nice and works much better then the kdebluetooth app,

I am trying to write a script to modify /etc/fstab that will add entries for a number of partitions on different disks.
The only thing that I do not know how to do is to obtain a unique id such as the ones in /dev/disk/by-id/ to address by from a given partition (ie /dev/sdb1). In my fstab I noticed that in installation the system added fstab entries that are unique (in /dev/disk/by-id/)
I could simply do /dev/sdb1 and so on, but I would prefer a unique identifier so that each mount point is tied to a partition on a specific and unique physical drive.
i need this to be script-able if possible, if not I would still like to know.

you have to read from many devices separate devices and make it look like a single one. It sounds very much like a device driver to me, perhaps... but getting my hands dirty with kernel code sounds like a daunting task for me that I've never done it...

I had previously been having loads of problems getting my wireless printer to work with Linux [http://ubuntuforums.org/showthread.php?t=1453697]. Everything is working fine now. However, something that confused me is that whenever I tried to ping the printer _before_ I got it working, it would fail with a _different_ IP address. That is, the command 'ping x.y.z.3' would fail with a message saying it was unable to contact 'x.y.z.2'
Now I am looking at my router - for something unrelated - and I've noticed that rogue IP address shows up in the list of connected devices. It has a MAC address but for the device name it lists "<unknown>". Should I be concerned about this? how to figure out what this device is?

I recently installed a new sound card, and I need to find out how to change the default device. Currently, I'm dual-booting Windows, and I had re-enabled the on-board audio in the PC's bios. After doing that, Debian started detecting that on-board as the default sound device. Is there a way to set my sound card to be used instead? I found out that the 'alsaconf' utility has been phased out. I"m currently running Debian testing, for amd64.

i have an isolated LAN (no connection to outside) with 3 fedora boxes. Suppose one of the boxes has an IP device connected to the serial port. We use SLIP and slattach to configure it and we can ping the device from every fedora boxes. Is it possible to bring the external device (192.168.1.9) to the set of LAN devices that receive LAN broadcasts?
box 1: 192.168.1.1
box 2: 192.168.1.2
box 3: 192.168.1.3.
It runs slattach and uses 192.168.1.9 to address serial connected ip device. I set up this scenario and the external device is ping(ed) with success but if I build a socket udp program that sends a broadcast to the LAN all the fedora boxes receive it except the external serial device. Why.
