Hi,

This patch is required to fix up the jumpshot driver, and to supress the 'unneeded entry' message for another device which uses the same VID/PID/rev for multiple different versions of the device.

Could you please elaborate on this part of the patch? I'm working on a usb-storage driver which I'll submit to you when its done - the code so far is basically a hybrid of jumpshot and shuttle_usbat.
One of my testers has run into problems when plugging in the device - namely, the SCSI layer requests a READ_10 on the very last sector of the disk (or, if our sector count is off-by-one, perhaps its asking for a read on a non-existant sector?). It fails, retries, fails, ..., and eventually gives up and goes on to create sda1 (the driver works fine except for the delay on plugin...).
Does the above patch fix the same issue on the jumpshot?
Thanks. Daniel
