Are you talking about rts5139? It does not work for me either, and it
breaks other usb devices (mice, usb storage, etc.). So I just
blacklisted it since I can live without it. :)

Back to the wifi issue: I have built the 3.4.0-rc1, and to my surprise
ubuntu/gnome3 boots without a hiccup, though previous problems still
exist:
1. kernel not detecting wifi device if hard rfkill is enabled;
workaround by `echo 1 > /sys/bus/pci/rescan`
2. rfkill enable/disable does not emit events
3. wifi stops to work after toggling rfkill switch;

I just noticed the line, not sure what it means:
[  402.542020] rtl8192ce:_rtl92ce_read_adapter_info():<0-0> RTL819X
Not boot from eeprom, check it !!
