I have one

The rtlwifi/rtl8192cu driver turned out to be flaky for this device,
usually it stalls after a few minutes. Searching the web it seems
this is well known and everyone uses a patched vendor driver
(https://github.com/pvaret/rtl8192cu-fixes.git).
The rtl8xxxu driver ssems to work stable (I tested
the git branch rtl8xxxu-nextgen, commit 2e23469d74d7).
However, thoughput is less than one half compared
to the vendor driver. FWIW, rtlwifi seems to be a bit
faster when it works, but thoughput fluctuates a lot
and eventually it stalls. (Tested with iperf TCP in both
directions.)
