Hmm; I've added if_urtwn_load="YES" and some ifconfig...="WPA DHCP" lines
to rc.conf and surprisingly it came up OK after reboot. usbdump is full
of these lines (timestamps trimmed):
usbus0.3 SUBM-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=0,IVAL=0
usbus0.3 DONE-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=384,IVAL=0,ERR=0
^^^ sometimes 256
If I notice "checksum timeout" situation again, I'll post an update; thank
you for the tips.
