I'm updating our WhiteHEAT driver, and would like to have URB queueing

My advice continues to be to strongly avoid using bulk queueing
on 2.4 kernels ... on 2.6 it's even in the regression test suite,
but it took some time for it to be reliable even there. On 2.4,
having it work is more luck than anything else. On 2.6, having
it work is the way it should be: careful planning and testing
(and bugfixing!) has made it worth relying on.
The ftdi_sio driver does bulk URB queueing and runs into similar
problems with the uhci driver, but I found it worked okay using the
usb-uhci driver instead. Well, this was a couple of years ago:
