Hi,
I've got a 256MB flash drive (067b:2517), which is detected by the usb
modul:
hub.c: port 1 connection change
hub.c: port 1, portstatus 101, change 1, 12 Mb/s
hub.c: port 1, portstatus 103, change 10, 12 Mb/s

The scsi driver also detects it pretty well:
scsi0 : SCSI emulation for USB Mass Storage devices

WARNING: USB Mass Storage data integrity not assured

However, I cannot read or write anything from/to it:

I also attached a part of the log of the usb-storage driver which may be
important...
So, if anyone can help me, or say something hope-rising, I am awaiting it
(and please add my e-mail address to the Cc: field)
Thanks,
