Hi all,
I'm attempting to read the contents of Microsoft-branded Xbox memory
units. The Action Replay for the Xbox includes a USB to memory unit
adapter, presenting the devices as standard mass storage objects. The
Interact-branded memory unit included with the Action Replay registers
properly in Linux through usb-storage and shows up as a device.
However, another memory unit from Microsoft that I am attempting to
access is sending the wrong bInterfaceSubClass code (66 instead of the
expected 6). From what I have read this is probably universal to all
Microsoft memory units.
My attempts to override this using unusual_devs.h has given only
partial success. I've tried about eleven permutations of different
options for my entry but cannot get the device to fully register.
My best attempt has come from this:
UNUSUAL_DEV ( 0x045e, 0x0280, 0x0000, 0x9999, "Microsoft Corp.", "Xbox
Memory Unit", US_SC_SCSI, US_PR_DEVICE, NULL, US_FL_SINGLE_LUN |
US_FL_FIX_INQUIRY ),
which shows the device and its size (along with numerous USB device
resets). The device attaches to /dev/sda but attempts to access it
merely reset the process, causing the device to reset and subsequent
be rediscovered again:

Any help that anyone can provide is greatly appreciated. Is
unusual_devs.h the appropriate method to deal with such a device?
What options are most likely to work?
Thank you in advance!
