We just picked up a remanufactored Sony Clie PEG-SJ33/U and ran
into some problems:

uvisor0 at uhub2 port 2
uvisor0: Sony Palm Handheld, rev 1.10/1.00, addr 2
uvisor0: init failed, STALLED
...
uvisor0: at uhub2 port 2 (addr 2) disconnected
uvisor0 detached

There is currently no memory stick, but when is MS Import is started:

umass0 at uhub2 port 1 configuration 1 interface 0
umass0: Sony Sony PEG Mass Storage, rev 1.10/1.00, addr 2
umass0: using ATAPI over CBI with CCI
atapibus1 at umass0: 2 targets

The usb bus apparently locks at this point. No further response
from an usb device occurs until after the host is rebooted.

indicate similar problems. Were the above two ever resolved?
