I have been debugging the usb problems some more. Your were
right in your assumption (thanks for the pointer) about lack
of calls to bus_dmamap_sync(). In usbdi.c bus_dmamap_sync()
does get used for transfers that move data from PC to USB and
it is used for transfers that move data from USB to PC. But
someone forgot that control transfers consist of possibly two
data chunks : the request itself and optionally a buffer of
data that should be transfered to or from the USB device. On
requests to the control endpoint without additional data
bus_dmamap_sync() didn't get called. For some reason my first
tests with umass worked (due to enough cache poisening I
guess). The attached patch adds a call to bus_dmamap_sync()
to usbdi.c and now all devices I have tried work out of the
box. I have successfully transfered large files using the
if_axe driver and I have mounted several different umass
devices.

marked INP_DROPPED or INP_TIMEWAIT:
o return ECONNRESET instead of EINVAL for close, disconnect, shutdown,
rcvd, rcvoob, and send operations
o return ECONNABORTED instead of EINVAL for accept
These changes should reduce confusion in applications since EINVAL is
normally interpreted to mean an invalid file descriptor. This change
does not conflict with POSIX or other standards I checked. The return
of EINVAL has always been possible but rare; it's become more common
with recent changes to the socket/inpcb handling and with finer-grained
locking and preemption.
Note: there are other instances of EINVAL for this state that were
left unchanged; they should be reviewed.

way I intended due to licensing restrictions. I had intended
that it would be defaulted on, with opt-out possible for
companies that don't accept the CDDL. The FreeBSD GENERIC
kernel has to be entirely BSD licensed, so the only alternative
would have been to make KDTRACE an opt-in option. That isn't
a design I favour.
Remove reference to mount_fdescfs(8), since mount(8) calls nmount()
directly to mount an fdescfs filesystem, instead of forking an
external mount_fdescfs program.
bfe_init_locked() wasn't sufficient to bring the chip back to life, it also
required a call to bfe_chip_reset() during resume.
