View 4 Repliesi booted up this morning and got a surprise. when i plug in a usb drive normally, it pops up in the k message box, and i can choose too mount it. then it mounts no problem.
when i turned on the computer today, however, i plugged in my usb drive, and clicked to mount it, and lo and behold, i got a strange message:
'Could not mount the following device: USB 8GB'
when i choose more information, i get this:
Code:
org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1 matched rules; type="method_call", sender=":1.12" (uid=8691 pid=2415 comm="kdeinit4: plasma-desktop [kdeinit]) interface="org.freedesktop.Hal.Device.Volume" member="Mount" error name="(unset)" requested_reply=0 destination="org.freedesktop.Hal" (uid=0 pid=1887 comm="/usr/sbin/hald))
im not entirely sure what this means. i can mount the drive manually through the terminal if it's running as root, but thats not a particularly practical way to do things, as i am a student and often have to switch USB drives and ipods many times a day.
I've got 2 problems:1. How can I use the find command to search for devices files?2. I need to find all files thaare 6 months (or more) old and that have a size of 2 Mo or more. What would the code look like?Oh and also, how can I use the cat command to insert text in a file?

This is the information lsusb gives:
skerit@KIP-DU-SKER:~$ lsusb Bus 008 Device 002: ID 0bc7:0001 X10 Wireless Technology, Inc. ActiveHome (ACPI-compliant)
But this tells me nothing about where the device file is! How can I find that, or create one myself?
Recently, I created a device sc0 through device mapper. The divice could be found in /dev/mapper/sc0. My problem is that the device doesn't exist in /dev/partitions which will block my following test.BTW, I found dm-0 in /dev/partitions. Is it the same as /dev/mapper/sc0? But the device /dev/dm-0 doesn't exist!
View 2 Replies View RelatedI'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
View 2 Replies View RelatedI 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?
View 1 Replies View RelatedI'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.

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...
View 2 Replies View RelatedNot long ago I lost all sound, but I got it back eventually-the system wasnt snesing my usb speakers.
Now its stopped recognising them again and I cant remember how I got it back before.
How do I find a list of USB devices?
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.
View 4 Replies View Relatedi 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.
When I connect my Treo 650 with a USB cable it works sometimes and not others. A little investigation showed
that it always works when I see the Palm device listed in the output of lsusb. While trying to diagnose why it appears sometimes and not others, I discovered that it sometimes appears in /proc/bus/usb/devices and not
in lsusb. I didn't think that was possible!
I've tried running kudzu (the Red Hat hardware discovery tool) and killing and restarting udevd.
Dual booting 10.10 and windows XP.
1. Where do I find my windows files when I am booted up in Ubuntu?
2. Where do I find and manage USB devices. My second monitor doesn't turn on in Ubuntu. It uses a USB attached device to connect.
There are probably some other things I should ask but am too new to know it.
i installed ubuntu today by installing Wubi and after downloading i rebooted computer and selected ubuntu but i got an error saying 'Try (hd0,0): FAT16: NO WUBILDR' and there was few more but i forgot and at the end it says 'Cannot find GRLDR in all device Press CTRL+ALT+DELETE to restart' it used to work when i had vista.
View 3 Replies View RelatedI'm running wubi on XP machine. Started out originally with 8.04, and gradually upgraded to 10.04. Recently, I was creating linux bootable USB drive, and put it in my system to see if it would work. After booting the LiveOS, and rebooting my machine, I know get the error Cannot find grldr in all devices when booting Ubuntu. I don't know what grldr is, but I assume it is the GRUB Loader.
Did booting the LiveOS screw with my MBR perhaps?
How can I fix this, and if not, is it possible to reinstall wubi, without losing anything of what I have now?
How can I find all the devices(printers,etc...) and computers along with their OS if any installed that are connected in my intranet (devices/computers may be down here)?
I did this earlier using netstat or nmap not sure what I used and how I did.
I've got three network devices on a laptop:
1. Built-in ethernet LAN
2. Built-in ethernet WLAN
3. PCMCIA ethernet LAN
I installed Ubuntu Server on this computer without the last one inserted.I inserted the last one today, and it lights up when i put in the cable. To be sure if Ubuntu has found it, I tested with the install CD and could see that it found all three at the first part of the installation where I have to chose a primary device.I can't get my WLAN card working, neither do I get my PCMCIA LAN card working. The third card, this PCMCIA card, has worked on Ubuntu Desktop using another laptop. And as said, the setup finds all three.
I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:
[Code]....
I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:

I'm installing 11.4 as a guest under Citrix's XenServer. The only access to a guest's graphical desktop is via VNC.The problem is that I can't achieve runlevel 5 as X can't find any devices. With 11.3 I was able to run Sax2 and add a dummy screen device to Xorg.conf that it created.When Sax2 was removed from 11.4, what was the fall-back for configuring X?

How can i find through terminal that which devices are external and which are internal.
By external i mean devices attached to USB port. For Example, USB Drive, Portable USB HardDrive etc
By internal i mean devices attached internally. For Example, SATA Harddisk etc.
In my last installation of debian (Squezee unstable), i dont have problems with the sound.But with my new installation of squezee, when i tried to activate the volume control (With the gnome applet), the system told me this (Aprox).

If I plug in a cheap USB adapter, I'm able to connect and use the devices.My computer is a HP ProBook 4330s running Debian Jessie. And as far as I can tell the Bluetooth adapter is a Ralink rt3592 combination Wi-Fi and Bluetooth PCI card. The Wi-Fi works fine, but when i try to connect to a Bluetooth device, I get no search results.

The intention is to have this system dual-boot. When i first put it together, i decided to setup a raid5 array spanning 3 sata drives. I installed Windows 7 first, decided i'd get to Linux later. I left 150mb or so at the beginning of the array for /boot, and about 200gb at the end for my linux install. i'm getting to the linux install. My distro of choice is Fedora 12. I start the setup, and at the point where it's time to partition, the installer tells me that its unable to find any suitable storage devices.
I Crtl-Alt-F2 to a console, and fdisk -l. Fdisk reports three individual drives which all have partitions already. All have free space. None make sense. So i turned to google, and found some threads which explain that this chip doesn't run a true raid, rather its what's been referred to as fake raid. Which is that it depends on the windows driver in order to actually present the array to the OS, and that the best way to get by that on linux, is to break the array, and use LVM instead.
That's all well and good, but i lose two things in doing that. First i lose the resiliency of raid 5, and second, well, what does that do to my windows install? I've considered moving all of my data from windows to other machines, and then just starting from scratch, but i'd really much prefer a method of using the chips fake raid in linux. Is there a driver, or module which i can install to make this happen?
