This has been giving me a headache for quite awhile and I figure its time to ask for help.

I've searched the forum as best I could and didn't find anything that matched my problem.

I am using the X-micro wlan usb device, which should have the zd1201 chipset.

I am trying to use the opensource Zydass zd1201 at linux-lc100020.sourceforge.net/ on a 2.6.10 kernal running on debian sarge.

The driver compiles fine and will load with modprobe zd1201 but wont seem to register the usb device.

From loading the module I then tried unpluging and repluging the device and here is what dmesg tells me.

usbcore: registered new driver zd1201
usb 2-2: USB disconnect, address 3
usb 2-2: new full speed USB device using ohci_hcd and address 5

Any help or links to post I might have missed would be apriciated. Thanks

I got it to work very easily, on Mandrak 2006, should work on any other distro.

First, download the latest firmware and unpack it to (example) \home\user\temp
open command shell.
enter su (superuser) press enter
enter your password for root
enter make
The firmware/driver is now installed to correct path.
Remove X-micro wireless USB and plug back in again.
Open network control panel, select add new network/device, select wireless, select WLAN device (it may even display the same name of you other onboard PCI cards). I have a 3com PCMCIA NIC, it showed the eth0:3com nic and WLAN:3com... so I chose WLAN 3com.
U might then get asked to enter your wireless networks SSID (the name you gave your wireless network on your router's control page) and the WEP key (if any).
Then select the type of WEP network type (open/shared, etc), if any.
Go to Finish
On your desktop next to time you might see 2 disconnected plugs, right click, select your wireless network. You might now get a window showing your networks, click connect. On the network status, there should be a button "Thernet connect". click this. you should now see bytes received/transferred on the wireless network.
Your connected and can surf.
I almost gave up in frustration, as my use of linux would've depended on getting wireless connection going.

BTW, this was how I got this card working on Mandrake 2006. Otjher distros might be different.
