Hi, I'm porting a wireless usb driver (if_run) to freebsd current, and I got stuck. Once I "ifconfig wlan0 wepkey 1:0x... weptxkey 1" I cannot call usbd_do_request() any more. Even ifconfig didn't exit. Chipset supports h/w en/decryption, so cannot write keys on chip. (It works without encryption, by the way.) So, I tried the same thing on another device, linksys wusb54gc with if_rum. It worked fine, but about 3 to 4 min later. (Just left it alone.) It started giving error rum0: could not multi read MAC register: USB_ERR_TIMEOUT and rum0: device timeout when ifconfig wlan0 down, rum0: could not multi write MAC register: USB_ERR_TIMEOUT which means failed on usbd_do_request() (This could be totally different issue.) Any ideas, patches, or walkaround?

I get a panic panic: mtx_lock of spin mutex(null) It works fine before ifconfig wepkey. __________________________________________________________________ Yahoo!
