Error should be returned from this function only

Scsi layer will do it itself. There is no need to reimplement its logic.
If you take a look at scsi various controllers implementation of bus
reset
disconnect() and probe() should be simulated only when
usb_reset_device() result was successful, as it is done now.
The only change is that scsi layer now allowed to make later one more
attempt to perform the request.

Failed usb_reset_device() means only that reset is not yet completed.
If we will return success from bus_reset(), scsi layer will wait for 5
seconds during which device will probably reconnect.

I have problems with USB 2.0 IDE adapter connected to USB 2.0 port on

I am using 2.4.20-pre7 with patches sent to this list David Brownell
(older version hangs after loading ehci-hcd).
The device works for some time, but when read command timeouts the
following happens:
