XMicro Wifi USB Problem

Question

Hello I have ubuntu installed on my pc. I Have XMicro-WLAN 11g USB
Adapter. I have been trying days together for getting the Adapter up
but my device doesnt seem to get detected. Which driver would be
required to be installed in Linux For the same. Please help me. I have
tried googling and installing bcmwl driivers but no avail. I also tried
the fwmcutter way still the device doesnt get detected. Which is the exact kernel version required as i tried using zd1211-4916_0.2 with kernel version 2.6.15 and it gives error during compilation for URB_ASYNC_UNLINK undeclared.
