CentOS 5 Hardware :: USB Device Descriptor Read Errors
Aug 20, 2010
I'm designing an embedded USB device. When I connect the device to the computer, I get the following messages:
usb 1-3: device descriptor read/64, error 2
usb 1-3: device descriptor read/64, error 2
usb 1-3: device descriptor read/64, error 2
usb 1-3: device descriptor read/8, error -71
usb 1-3: device descriptor read/8, error -71
usb 1-3: device descriptor read/8, error -71
Note that other USB devices work fine. I am fairly certain that the problem is with my hardware. I'd like info on what these error messages mean to help my debug. Searching Google I wasn't able to find any explanations about what these errors mean exactly.
I'm running Cent OS 5.4 with kernel 2.6.18-164.el5 on an i686

I'm having issues with getting my USB ports to work on my server. USB keyboards, mice, drives, flash drives, card readers, etc. will not work on this server.

While I had the case open to swap out a network card I thought I would drop in an old USB card (previously used with no problems on a machine running Debian) however on boot I'm now getting some errors showing up. The card has been sitting around for a while so it could be an issue with the card.

For the record, I'm having the same issue as the OP with Lucid with a backported 2.6.35-28 kernel and a Samsung scx-4623fw printer hooked up via USB. Same symptoms - lsusb hangs until the printer is unplugged, devices aren't recognized, etc. Dmesg output includes a bunch of device descriptor errors:
[603.091961] usb 7-1: new full speed USB device using ohci_hcd and address 9
[618.241335] usb 7-1: device descriptor read/64, error -110
[633.521986] usb 7-1: device descriptor read/64, error -110
I suddenly started having a bunch of USB issues (including complete system locks whenever I plugged in a logitech USB mic) around early march with the stock lucid kernel. Everything was fine before that.

I tried to get 3d hardware support in my FC12 install. I grabbed the latest appropriate drivers from the nvidia website for my Geforce 6800 XT graphics card. I changed the inittab file to boot to command line, ran the .run file as root and ran into a couple errors doing so.
I then proceeded to use yum (which i do like but this is a bad scenario for me thus far) to update my drivers to the suggested kmod-nvidia drivers that exist out there. Once all of the installation was completed I rebooted and got the following error displayed at the top of my screen after the fedora loading bubble disappeared. The system just seems to hand at this point....
"usb 2-1: device descriptor read/64, error -62"
I did a hard boot on the machine and tried again, this time i pressed the esc key to watch the interactive startup screen and noticed that after "enabling local filesysem quotas: [ OK ]" i get a
***Warning -- SELinux targeted policy relabel is required.
*** Relabeling could take a very long time, depending on file
*** system size and speed of hard drives.
This will continue with asterisks across the screen until eventually it stops and then I am stuck as to what to do from here on out. What could possibly be causing all of this mayhem?I have tried to use the fedora core 12 install cd to launch it into "rescue mode" and from the bash command line proceed with modifying my grub.conf to not use the "newly installed kernel (2.6.32.11-99.fc12.i686)" that was installed with yum during my kmod-nvidia driver installation.

I have a recent install of ubuntu 10.10 on a brand new rig, and everything appears to be working properly but I get these 2 errors during bootup that seem to make the book process take a bit longer than expected but haven't actually noticed a problem in performance.
[6.394416] hub 3-1:1.0: config failed, can't read hub descriptor (err -22)
[6.752860] hub 3-2:1.0: config failed, can't read hub descriptor (err -22)
I have been unable to find a site with information on what err -22 means. From what little I have found on the issue it seems to be something with the usb 3.0 hubs on the back of my motherboard?

I have a server that has a Fibre Channel mount that is having issues. When I can in this morning I found that it had switched to read only. Now looking through /var/log/messages I see that there are errors reported on the disk. I know that i will need to run fsck on it, but I do see lines about the device mapper failing for mpath0 first, which is the device which is mounted. I am wondering if someone can take a look and see if this is just a drive issue, or an issue with the fibre channel connection.

Recently my Ubuntu system decided to crash. Sometimes the mouse freezes, sometimes I just can't open anything, and other times I can access the terminal but can't write. I can open files as read only both in my /home partition and in /var/log, but I can't write at all. Sometimes I get Bash: input/output error. I *can* "ls /proc", if that makes any difference.
I find that if I reboot, the problem goes away for a few minutes and then reoccurs. I can read/write to my other (windows) drive, although when I did a chkdsk in win7, I get a "An index entry from index $0 of file 25 is incorrect" message. Is the disk failing? Just a few bad sectors? Maybe the filesystem is corrupt? Why can I read but not write?

I recently upgraded from Lucid to Maverick, which went fairly smooth. Then I upped my RAM with some new memory sticks (4Gb to 8Gb). Since about then, I'm seeing these errors in syslog:
Code:
Jun 6 22:23:52 howler console-kit-daemon[1224]: WARNING: Failed to add monitor on '/dev/tty2': No space left on device
Jun 6 22:23:59 howler console-kit-daemon[1224]: WARNING: Failed to add monitor on '/dev/pts/0': No space left on device
I also get errors when running "tail -f" as root:
Code:
tail: cannot watch `/var/log/syslog': No space left on device
I searched around and I found some other reports of the tail -f error, with the suggestion of increasing fs.inotify.max_user_watches. I set it to 16384, and that at first resolved the tail -f problem, but now I'm getting that error again even after upping max_user_watches.
I know swap is suggested to be approx. the same size as RAM, but with this upgrade RAM is now bigger than the 5.7G of swap.

I am having trouble with connecting my Sony Ericsson phone with my Ubuntu 9.10 using USB. It doesn't matter how I choose to connect it - "File Transfer" and "Phone Mode" - both does not work. The phone IS charching, when it is connected, but it doesn't shows anywhere. When I type "lsusb" in terminal, it does not show me my phone. When I look in "/var/log/messages" there is NO error. It does not even show the procedure of connecting and disconnecting the phone. What could be the problem?

My old Creative Zen MP3 player has just gone titsup - it's gone into recovery mode and attempts to reload the firmware come up with device not connected errors (even under Windoze XP) So I'm looking around for a replacement and the Cowon D2 looks good as it takes SD cards like the zen (and I'd just bought 2 new 8Gb cards). The Zen used mtpfs which worked under linux but not well an I believe the D2 just connects as USB memory. Anyone out there using a Cowon D2 under Linux?

I try to set up a 5 nodes cluster and a shared Coraid Storage with conga but it fails with "Shared Storage Support" checked.The message is:'A problem occurred when installing packages: Packages of set "Clustered Storage" are not present in available repository' and it is shown under every node on the next sceen after I submit.The pc where conga runs is on the same subnet (192.168.xxx.xxx) and it has the same /etc/hosts of the other nodes.In that pc runs a proxy too and the nodes go out through it (that pc has 2 NICs)Every node (2.6.18-128.1.14.el5-xen-x86_64) is patched whith the last yum update (this morning) the same is for the pc (2.6.18-128.1.14.el5).Every node has 4 NICs , 2 NICc towards the storage the others in bonding towards the WAN.Every node is exactly alike, they have been installed with the ks.cfg generated from the first node and they all have the support for Clustering, Virtualization, and Clustered Storage.

[i use Ubuntu linux 10.04 LTS - the Lucid Lynx] i tried to print a document and i got the following message from the "document print status (my jobs)": "There was a problem processing document 'take it easy' (job 400)" i tried to print other things but i got the same error. after any print request i sent the printer asked me to release the paper it took, and when i release it, it printed this:"Unable to open the initial device, quitting." i have "HP Device Manager" installed on my computer, and lately i tried to install a wireless printer (officejet 4500 g510n-z) through it, and it failed because the connection between the printer and my computer disconnected before the terminal finished the installation. i didn't try to print with the deskjet right after it but now when i try- it doesn't work, so it might have something to do with my current problem... also when i looked at the HP Device Manager i saw the deskjet printer icon marked with X so i used this program's option "Setup Device" and the X mark disappeared.. and it still doesn't work.

I am trying to add/delete files from my HTC Evo through ubuntu via enabling file sharing on the device. Ubuntu detects the drive, and mounts it up so that I can browse/read files off the device. However, I am not able to do any writing to the device because it is mounted as "read-only". The only wierd thing is that it worked last week, and I have not changed any settings on my system. Where should I start? Is the auto-mount for USB drives located in "/etc/fstab"? because here is the contents of that file, and I dont see anything for usb mounts:
Code:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name

I'm playing a little bit with OpenCV but the webcam that i have on my desktop isn't app-friendly... so i could not get it working with OpenCV, it's a 0ac8:301b Z-Star Microelectronics Corp. ZC0301 WebCam and it worked out of the box with Cheese and after a little bit of tweak i get it working with camorama also.But some apps, like Skype and OpenCV demos doesn't work, believe me, i tried everything to get it working, i tried even upgrading to a very new kernel.
So i had the idea to create a "virtual" video device and using some app that can read the wcam i could print the wcam's output on such device, which should be compatible and app-friendly, so i would use that device always.

I need to change a filename but when I boot up I get the message root device is read-only. Is there a way of changing this so that I can change the filename. I have a Mac Pro running Leopard OSX. The graphics card an NVIDIA 7500GT or driver has failed. It was suggested elsewhere that I change the relevant kext files to filename.kext.old, which I did, now when I try to boot start in OSX I get a message in various languages telling me to restart. I have tried booting in safe mode and from original Installation CD. In Safe Mode I get the same multi language splash screen, from CD I still have the graphic card problem, screen freezes and artifacts appear. So I boot up straight into CLI by holding down CMD-S hoping to be able to change filenames back but it says device read-only.

My wife is purchasing a netbook with no internal CD/DVD writing device, so we plan to purchase an external CD/DVD USB-2.0 read/write device. Our local PC shop has the following 3 external USB-2.0 DVD read/write devices:
(a) Samsung DVD-Burner SE-S084F/RSBS [not listed on Samsung site - too old ? ]
(b) LG DVD-Burner GE24NU21 USB2.0 [not listed on LG site - too old ? ]
(c) Super-Multi Portable DVD Rewrite (GP10 Lite USB2.0 Slimline) GP10NB20 (mentions Mac OS/X support, which is encouraging)
None of those are listed in the openSUSE HCL. Has anyone successfully used any of these with GNU/Linux (my google surfing on this revealed no GNU/Linux complaint nor any success stories) ? Or is there another such external USB-2.0 read/write DVD burner device that is recommended ?

On one of my machines the DVD/DVDRW/CDROM drive appears as /dev/hdc and is not identified as an optical drive by HAL. It is owned by root: disk and thus no users get permission to read/write in the device (not even those in the cdrom group). This stops playing DVDs, ripping CDs, no notifications appear when a disk is inserted, etc. etc. When I set the permissions for all to read/write from the device then users can access but still no notifications are shown.
On all my other machines the optical drive is identified as /dev/sr0 and is owned by root:cdrom . All have Slack 13.1 . Previously with Slack 12.2 this machine still had the drive in /dev/hdc but the permissions were right (I think because I added it to /etc/fstab with options for users to access it). I believe the problem is down to HAL not setting this drive to the correct group, but how do I fix it? I hate HAL, it has a mind of its own, just like in the scifi movie
