Linux 2.4 doesn't create hotplug events, unlike 2.6, so it doesn't get
to run usbmodules, hence no control junk on the wire while bulk
transfers are in progress.

Try changing max_sectors in linux/drivers/usb/storage/scsiglue.c to a
smaller number (i.e. 16 or 32 or 64) and see if that improves the
transfer speed.
Cool, 32 or 64, about 5x faster than when i went to

Hi,

FW work great since 2.6.2, connecting the USB to a machine running 2.4.23
instantly rebooted the machine, and in 2.6 (currently 2.6.5rc1bk2) it
doesn't work either:

there's a race condition between close and disconnect in that driver

Hi,
you must use set_current_state() only after usb_submit_urb() with GFP_KERNEL
as second argument, because it may sleep to allocate memory and is woken up
resetting the state to TASK_RUNNING. In that case you had a busy polling loop.
Furthermore, always use wake_up unconditionally. It checkes an
