I too have done this with High speed USB devices: SanDisk Micro Bonzai sold by Simpletech. My dmesg was device descriptor read/64 error -71
The work around works for me with SuSE 10.1 Kernel build 2.6.16.21-0 25 built Tuesday 19th Sept 2006 6:46:56 AM CDT on eisler.suse.de
What appears to be going on is that after so many entries in a USB table (which is the SCSI Stub) the High Speed Devices no longer can create an entry in the appropriate time.
Personally I would vote that this is a module issue. However it did not appear until unit was updated to above kernel. Google gives many hits on "descriptor read/64 error -71"
Same SuSE configuration was on P4 2.2G HP xt395 Laptop 1G/60G(12 Mhz USB), Micron Clientpro PIII 1G 512M/40G (12MHZ USB) and Micron Clientpro PIII 1G 512M/60G on same hour/day so was quite repeatable.
USB drive was placed in W2K and XPro boxes and was recognized immediately

Morgoth April 16th, 2005, 01:50 AM HI all. I am having a little trouble with my USB thumb drive. I have successfully installed Kubuntu on both my laptop and desktop systems, however I cannot get my thumb drive to work on my desktop. It works fine in the same computer on my Windows ( sigh, I know ) XP partition and it works great on the laptop, so I figure it can't be the usb port or the drive itself. I think something got broken when I installed but I'm still fairly new when it comes to ripping around in the guts of Linux and am not sure where to even start looking. I have tried to mount the drive manually, but got an error saying no device ( sda1... or sdb1... ) and in fact there are no entries at all in /dev for sd"anything". When I insert the drive and do a dmesg, it shows the following errors:
usb 4-6: new high speed USB device using ehci_hcd and address 2 usb 4-6: device descriptor read/64, error -71 usb 4-6: new high speed USB device using ehci_hcd and address 3 usb 4-6: device descriptor read/64, error -71 usb 4-6: new high speed USB device using ehci_hcd and address 4 usb 4-6: device descriptor read/64, error -71 usb 4-6: new high speed USB device using ehci_hcd and address 5 usb 4-6: device descriptor read/64, error -71 usb 4-6: device descriptor read/64, error -71 usb 4-6: new high speed USB device using ehci_hcd and address 6 usb 4-6: device descriptor read/64, error -71 usb 4-6: device descriptor read/64, error -71
If anyone out there has seen this or has any insight into my problem I would greatly appreciate a reply.
robajz June 3rd, 2005, 01:33 AM Hi,
I found this https://www.redhat.com/archives/fedora-list/2005-March/msg04036.html ... type, as root, modprobe -r ehci-hc ...
it's just workaround but worked for me, don't know why. May be next kernel release may fix it.

Morgoth June 3rd, 2005, 01:58 PM IT WORKS!! :) I cannot thank you enough Robajz ( first born ok? ) As you can tell I posted this 2 months ago and nothing. I had just about given up trying to find a solution. I know it's not a life-threatening situation, but it was inconvenient.
Once again thank you. Morgoth
