>Description:
I rebuilt my machine today and thus incorporated the USB changes that
have been MFC'd some days ago by julian@. Now I observe duplicated dmesg
entries for all newly attached USB devices, e.g.
umass0: USB Solid state disk, rev 1.10/1.00, addr 4
umass0: USB Solid state disk, rev 1.10/1.00, addr 4
Worse, the machine crashes when I remove USB sticks (tried various
models, all behave the same), saying
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
umass0: at uhub1 port 2 (addr 4) disconnected
umass0: detached

I did already apply yesterday's change to uhub.c (1.21.2.11).
My previous kernel was built on 29th April and works fine. This already
includes the ehci, uhci and ohci changes that were done on 26th April.
So this problem must be related to the USB changes on 30th April.
