No problem.

That card is the 1x2 variant.

I tested my sample of that card using the wireless-testing git repo as merged 
with mainline on May 13. I could connect with WEP, WPA, and WPA2 APs and the 
connection was stable for at least 2 hours.

Performance could be improved. For WEP and WPA, netperf shows about 10 Mbps for 
RX and TX. For WPA2, it is not that good. I will compare these results with the 
latest vendor driver, but it does not build on 3.10 and I do not have time to 
sort that out now.
