Hi,
I've got a USB mass-storage device which I'm trying to use,
so far no joy.
The best I get is a modprob usb-storage showing a scsi device,
but me being unable to work out what to do next.
Here's a session of me trying to mount this beast.
lspci -v shows:
00:1f.2 USB Controller: Intel Corporation 82801 82810 Chipset USB (rev 02)
(prog-if 00 [UHCI])
Subsystem: Intel Corporation: Unknown device 2412
Flags: bus master, medium devsel, latency 0, IRQ 9
I/O ports at 1820
(I've tried using usb-uhci, and uhci - I'm not sure which I should
be favouring).
root@hell:~# modprobe usb-uhci

(I've hacked usb.c - so that I can see:
descriptor.idVendor = 0xb86
descriptor.idProduct= 0x5110
descriptor.bcdDevice= 2 )
Length = 18

So here I see in that the driver is usb-storage - but that module
has a reference count of 0, and it doesn't identify it as a mountable
device.
I tried adding the following unusual_device entry - no joy.
{ 0x0b86, 0x5110, 0x0200, // skx - also tried 0x0b86, 0x5110, 0x0100
"flash-steve", US_SC_SCSI, US_PR_BULK, US_FL_SINGLE_LUN},
That gave me:
Host: scsi2 Channel: 00 Id: 00 Lun: 00
Vendor: `c\ Model: < a Rev: P\
Type: Unknown ANSI SCSI revision: 06
But I was unable to mount it..
Any more information can be generated upon request.
