Here is dmesg output from 'kldload rt2860_sys.ko' after running 'sysctl
debug.ndis=1':
no match for ZwWriteFile
no match for ZwCreateFile
no match for ZwReadFile
ndis0: <802.11n Wireless LAN Card> mem 0xfbef0000-0xfbefffff irq 19 at
device0.0 on pci1
ndis0: [ITHREAD]
ndis0: NDIS API version: 5.0
NDIS: open file /compat/ndis/rate.bin failed: 2
attach done.
halting done.
/var/log/messages doesn't have anything new to add -- an unknown USB
device is detected but that's the camera so I'm not worried.
