I'm doing my best to port a driver (atuwi) for a Linksys WUSB11v2.8 driver that was written for FreeBSD 5.x to 7.1, but as I'm not a kernel hacker by any means, I'm having a few problems. I've managed to update Daan Vreeken's atuwi so that it compiles and loads, but I haven't yet got it to connect to my wireless network. When I load driver, I get a couple warnings: atuwi0: WARNING: using obsoleted if_watchdog interface atuwi0: WARNING: using obsoleted IFF_NEEDSGIANT flag I've Googled both messages, but haven't found any discussion on when these were obsoleted and what you're supposed to do instead. My ifconfig status shows up as: atuwi0: flags=108802<BROADCAST,SIMPLEX,MULTICAST,NEEDSGIANT> metric 0 mtu 1500 ether 00:0c:41:5a:48:5f inet 10.0.42.223 netmask 0xffffff00 broadcast 10.0.42.255 maclabel ?biba,?lomac,?mls,?sebsd media: IEEE 802.11 Wireless Ethernet autoselect status: no carrier vlan: 0 parent interface: <none> ifconfig: unable to get channel information ssid "Air Mousey" I notice that "status" shows up as "no carrier", and I'm not sure what exactly that means and why it's unable to get any "channel information". I also notice question marks in the "maclabel" line, and I suspect that might be indicative of a problem. My biggest problem is that I can't find any documentation on the "right" way to structure such a driver. I've looked at other if_xxxx drivers in the usb/ folder, but each does its thing in its own way. Both OpenBSD and NetBSD adopted Daan's atuwi driver and have had it running for a while, but unfortunately no one in the FreeBSD world took it on. If anyone has any insight or can point me in the right direction, I'd be greatly appreciative. Thanks, Patrickhome | help
