Whats what the log said, so yes (assuming the kernel report is correct).

See attached file lsusb-v-k3.1.8-2.f16.x86_64.txt.

See attached file lsusb-v_k3.2.0-rc7-sparc64.txt.

I used the same port when moved to others when back to original port.

Well.... This is what I did this morning:
1. Reboot.
2. Insert thumb drive in first usb port. Run 'lsusb -v'
3. Removed thumb drive.
4. Inserted an old logitech wireless mouse (the receiver) in another usb
port (I think is an usb 1.1 device). Kernel reported this:

5. Removed the usb mouse receiver. Inserted the usb mouse receiver again
in same port. No reaction from kernel.
6. Trying to run lsusb -v. lsusb freeze (ctrl-c/ctrl-z/kill don't work).
7. Waiting for a while... See attached file messages-20120112
8. Reboot.

I tested with kernel 3.x as requested in one of the previous e-mails.
However, 2.6.32-5-sparc64 behave almost the same. thumb drive is
detected also fist time. Errors second/third time, etc. Still, after
several remove / inserts the thumb drive is recognized again (I only
tried this procedure once).
Sincerely,
Gabriel
