[lug] TP-Link WN722N USB wireless adapter not working, Ubuntu 10.04

[Jeffrey S. Haemer]

Yeah, dmesg says stuff, but not anything useful that I remember.

For the rest, I'll look tomorrow.  Well, no, if I get sucked in I'll waste
tomorrow just like I did today, so I'll probably wait a day and waste part
of the weekend. :-)  I'm thinking I should try ndiswrapper, maybe?

The dongle works fine on my 11.04 netbook, and the drivers it loads look
just like the drivers that get loaded for 10.04.  Figures.
