after attaching palm z22 to openbsd based laptop i got the following lines in dmesg:
uvisor0 at uhub1 port 2 uvisor0: Palm, Inc. Palm Handheld, rev 1.10/1.00, addr 3 uvisor0: init failed, TIMEOUT
device initialization failed and ucom(4) device is not created. attached patch for uvisor(4) driver is a hack for work with palm z22 device. after patch:
uvisor0 at uhub1 port 2 uvisor0: Palm, Inc. Palm Handheld, rev 1.10/1.00, addr 3 ucom0 at uvisor0 portno 0, sync
