Bug Description
Reproduced 5 times on 3 different machines (2 AMD, 1 Intel, all USB2) under Gutsy Gibbon Tribe 5
with this 2GB USB2 Flash drive
USBSTOR\
but not that 4 GB one
USBSTOR\
both FAT32 formatted.
Booting from gutsy-desktop-
Connect USB Flash drive, works fine.
Unmount drive.
(Cosmetic: drive led still flash slowly; would be better dark to imply safe disconnect, XP does that)
At this point the drive still shows by its manufacturer name in "computer", it can be remounted and unmounted normally.
Disconnect drive (no warning of unsafe ejection).
Re-connect drive (same or different port, identical result); drive fails to show at all, including in "computer"
Note: following re-connection the drive led flashes slowly for 2 sec, then fast for 2 sec indicating some activity; then slowly again until disconnect; the USB stack can still mount another USB drive on all ports.
Note: the drive's content is NOT damaged: it works just fine on another machine, or after reboot.
Repeat: this is dependent on the type of flash drive.
I am positive there is some "memory" that the affected drive was connected, somewhere in the booted PC, not the flash drive. Waiting, closing session, changing USB port, connecting another (not affected) flash drive does not help.

I am willing to try help on this annoynance
- is there a log of the USB stack that I could copy?
- is it worth to test with another Ubuntu/Linux release?
- I can send the USB drive for test to someone that feels in charge
