Oh well. To put it mildly, this driver is awful.
It compiles with frightening array overrun warnings in rtl8192c_rf6052.c, on load spews a ton of messages and then replies to a scan request with:
root@milhouse:~# ip link set up dev wlan4
root@milhouse:~# iwlist wlan4 scan
wlan4 Interface doesn't support scanning.
root@milhouse:~# iw dev wlan4 scan
command failed: No such device (-19)
Stand clear, here come the messages:
