Re: Use of USB "Disk on a key" devices

Kevin,

I purchased an 8Mb DiskOnKey device last week from PC World here in
London for 10 GBP kast Thursday. I attempted to get the device to work
simply byhacking its VID and PID into /src/sys/dev/usb/umass.c, but no joy.

The device appears to be a BBB/SCSI-transparent one according to its
configuration descriptor. After attempting to attach CAM, commands time out
and are then refused - the device does not respond to SCSI_INQUIRY.

There are a few further tips and tricks which I can perform, such as 6-byte
command conversion within the SCSI stack. I will probably attempt to pin
down further details of why the device isn't responding; I will be sure to
let you know.
