Hi, Just test 2.6.11-rc1 and it works now. I tested it cz I saw lots of
changes in usb=storage in the log not sure which item is applied. Do you
still need the info. with 2.6.11? When working the type of disck is like:

with 2.6.12-rc1

usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
Vendor: SigmaTel Model: MSCN Rev: 0100
Type: Direct-Access ANSI SCSI revision: 04
usb-storage: device scan complete
SCSI device sda: 501760 512-byte hdwr sectors (257 MB)
sda: assuming Write Enabled
sda: assuming drive cache: write through
SCSI device sda: 501760 512-byte hdwr sectors (257 MB)
sda: assuming Write Enabled
sda: assuming drive cache: write through
sda: sda1
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0

The Vendor and Type etc.. are the same if using 2.6.8. With 2.6.9, 10, and
11 it did not detect device.

Let me know if you still interested to debug it in 2.6.11 (I think no
need :-) )

Thank you

Cheers,
