Hi All,

As discussed a long while back, usbfs is currently missing bulk streams
support, and we ought to fix this. So this patch extends the usbfs API with
bulk stream support. Please review.

At first glance, it looks sane, nice job.

Note this patch-set is compile-tested only, since I don't have access to
any USB-3 devices using bulk streams. I've 4 different USB-3 disk-enclosures,
but none of them supports uasp :|  Yesterday I've finally managed to find
an USB-3 disk enclosure online which in its description actually advertises
uasp support, I should receive that in a couple of days, at which point I can
actually test this (which is why I wrote this patch set now).

What device did you find?  I have yet to see a shipping device with
streams...

I don't know about streams, I'm hoping that having a uasp device means it will
also use streams. So far I've been unable to get my hands on anything doing uasp,
but it seems the tide is turning and now I've found multiple. Now lets hope that:
1) They really support uasp 2) they use streams (not sure if that is optional
or mandatory with uasp).

This is the one I've ordered:

This one also looks nice, and plugable is known to be a Linux friendly company,
and they should be available in the US:
