My (now usually windows only) amd64 desktop box has ohci, but it doesn't
have any ethernet devices that 4 has support for (5 does, apparently)
so I can't easily give direct logs.
Booting i386 FreeBSD from an old partition taken to 4-STABLE from
earlier this month shows that the SanDisk CF redaer works fine with
mtools to read from (when I try to write to it I get lots of umass0:
BBB reset failed, STALLED) and the Iomega micro mini thumbdrive also
works fine with mtools for read/write.
The crucial gizmo does not work at all, I get a umass0 message, a
disconnection and then detatch message and then another "umass0:
Crucial Gizmo, rev 2.00/0.01, addr" message and nothing else, no da0;
can't re-use a leaf (minimum_cmd_size)!
umass0: at uhub1 port 4 (addr 2) disconnected
(da0:umass-sim0:0:0:0): lost device

umass0: Crucial Gizmo, rev 2.00/0.01, addr 2
umass0: at uhub1 port 4 (addr 2) disconnected
umass0: detached
umass0: Crucial Gizmo, rev 2.00/0.01, addr 2
Shortly after removing the Gizmo the machine page faulted in kernel
mode and crashed.
After enabling crashdumps I tried this again and the gizmo as the
first device worked;
umass0: Crucial Gizmo, rev 2.00/0.01, addr 2
umass0: at uhub1 port 4 (addr 2) disconnected

da0: 123MB (251904 512 byte sectors: 64H 32S/T 123C)
can't re-use a leaf (minimum_cmd_size)!
then I got a panic: ohci_abort_xfer: not in process context and a very
big crashdump;
IdlePTD at physical address 0x003ef000
initial pcb at physical address 0x00346b20
panicstr: ohci_abort_xfer: not in process context

Further down the rabbit hole, I build a kernel.debug and try to
copy things over to a flash drive to get them to another machine;
umass0: SanDisk Corporation ImageMate CompactFlash USB, rev 1.10/0.09, addr 2

This didn't crash the machine, at least.
Trying to reprovoke the crash it seems to only fail with a panic from
one pair of usb ports, the rest work better. I get another page fault
in kernel mode and it dumps;
IdlePTD at physical address 0x003ec000
initial pcb at physical address 0x00346b20
panicstr: page fault
panic messages:

That help any ?
