This 802.11b (11 Mbps) USB device also works with the Teac ITV-D500 standard definition set-top box, which is also known as a Netgem I-Player. It requires Atmel drivers to be installed, which can be done with the SuSE `online update' found within YaST.
Configuration can then be done from within `Network->Network card' in YaST. It was not properly auto-detected, so I got rid of the previous network USB device that I had and made up a new one. In my case I set it up with a static address and routing through my router address. Under `Advanced->Hardware details' you can find `Wireless Settings', where I chose `Managed mode/Infrastructure mode', set the Network Name (ESSID) and the WEP keys and open authentication mode (under the option Multiple Keys). Under `Expert settings' I could set the channel. I am not sure why `Encryption Key' is shown in the `Wireless Device Setting', since that field was filled with an entry I made under `Multiple Keys' anyway.
Sadly, the Network Name (ESSID) will not be properly adjusted if the ESSID contains an apostrophe ``'''. As root, edit the file /etc/sysconfig/network/ifcfg-wlan-bus-usb, although the exact file name may vary. Look for the WIRELESS_ESSID entry, which can be surrounded with double quotation marks if your ESSID contains an apostrophe/single quotes.
