Well.. if I could get the dump to actually happen, I could report it 
correctly, as it is, I will likely just have to take a picture of the screen 
when it happens again, although the last few times the driver dies, I simply 
restart the machine, so no panic, but I'll let it panic the next time, and 
take a picture with a digital camera if I have to..

I'm not sure how to rebuild just the module with that option URTW_DEBUG 
enabled.. I'm being told by some to just add the device to my kernel config 
along with the line "option URTW_DEBUG" .. but if there's a better way, let me 
know please.

Also, I suppose that means if I want the "any" I sysctl 
hw.usb.urtw.debug=0xffffffff right? Still a bit green with regards to 
debugging.

Thanks,
