Okay,
I have tried to make a new patch now.
Changes :
- New flag MAX_SECTORS_128 in include/linux/usb_usual.h
- Sets max_sectors per request of queue to 128 sectors if
flag is set in drivers/usb/storage/scsiglue.c
- New device entry for unusual_dev.h with rev id 0x0103 instead of
0x0000-0x9999 and with the new flag
Benjamin
