Bug 281265 – The hardware is fine, but all of a sudden I am uanble to mount a USB drive.

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Alex Weiss 2009-08-12 23:20:02 UTC]

Everything was working without a problem. However, I had to reboot the system at some point and then I was no longer able to mount my portable USB drive.as the device (sda1) never was created. A peek inside my dmesg reveals the following message over and over again:

usb 1-6: new high speed USB device using ehci_hcd and address 64
hub 1-0:1.0: unable to enumerate USB device on port 6

I built my kernel correctly as this did not change between the drive working fine and this problem.

Reproducible: Always

Steps to Reproduce:
1.mount /mnt/usbdrive
2.
3.

Actual Results:  
usb 1-6: new high speed USB device using ehci_hcd and address 57
hub 1-0:1.0: unable to enumerate USB device on port 6
hub 1-0:1.0: unable to enumerate USB device on port 6
hub 1-0:1.0: unable to enumerate USB device on port 6
hub 1-0:1.0: unable to enumerate USB device on port 6
hub 1-0:1.0: unable to enumerate USB device on port 6
hub 1-0:1.0: unable to enumerate USB device on port 6
hub 1-0:1.0: unable to enumerate USB device on port 6
usb 1-6: new high speed USB device using ehci_hcd and address 64
hub 1-0:1.0: unable to enumerate USB device on port 6


Expected Results:  
USB drive mounts and allows me to access its contents.

bugzilla is not a troubleshooting medium. 

You provided no kernel version, no clue about your system, and no details. *Something* must have changed. initial signs point to kernel or udev. Let's start with the basics, emerge --info, uname -a, /proc/config.gz. No guarantee that this is solvable, via bugzilla. A better choice is forums, mailing list, or irc (#gentoo). Thanks for understanding.

Kernel is 2.6.30-gentoo-r4 #2 SMP Wed Aug 12 23:58:59 BST 2009 i686 Intel(R) Pentium(R) 4 CPU 2.60GHz GenuineIntel GNU/Linux

Hi,

Fortunately, I try to keep old configuration files around (basically I just maintain a copy of the etc directory). I found a copy of some 'storage rules' there which, when copied into the /etc/udev directory, seemed to do the trick.

Sorry to clutter up the bugtracker.

No worries, glad you resolved the issue.

Hi there,

Unfortunately, the issue returned after I rebooted and installed a new kernel. Sometimes the device is found again, though not until I wait a very long time and goes through tons of those messages. Suddenly the device appears to find usb 4-1 which makes it happy:

usb 4-1: new full speed USB device using uhci_hcd and address 2
usb 4-1: not running at top speed; connect to a high speed hub
usb 4-1: configuration #1 chosen from 1 choice
scsi0 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
usb 4-1: reset full speed USB device using uhci_hcd and address 2

Anyway, I am really not sure why this problem suddenly emerged, but it's rather frustrating.

The bug in URL suggests that this may be a problem your controller has with S.M.A.R.T. - we don't currently package libatasmart, but if you're running smartmontools or sth. similar, you should be seeing similar problems.
