Hey i have been trying for like a week to install one of my to wlan cards on my laptop.

This is the error i get with the usb card from MSI

ndiswrapper: driver ms6823 (WLAN,03/09/2004, 1.99.309.2004) loaded
ndiswrapper (NdisWriteErrorLogEntry:314): log: C000138B, count: 2 (00000005), return address: d0ae877a
ndiswrapper (ndiswrapper_add_usb_device:363): Windows driver couldn't initialize the device (C0010006)
ndiswrapper: probe of 3-1:1.0 failed with error -22
usbcore: registered new driver ndiswrapper

and when i try with the pcmcia card from Sitecom.
My kernel crashes when i use modprobe ndiswrapper

It's working now i found an unofficial driver.

Unofficial ZyDAS zd1201 Wireless USB Adapter Driver for Linux

Try googling that folks it will help you.
