- This is a driver for wireless RNDIS devices.
- These are USB based adapters found in devices such as:
-
- Buffalo WLI-U2-KG125S
- U.S. Robotics USR5421
- Belkin F5D7051
- Linksys WUSB54GSv2
- Linksys WUSB54GSC
- Asus WL169gE
- Eminent EM4045
- BT Voyager 1055
- Linksys WUSB54GSv1
- U.S. Robotics USR5420
- BUFFALO WLI-USB-G54
-
- All of these devices are based on Broadcom 4320 chip which is the
- only wireless RNDIS chip known to date.
-
- If you choose to build a module, it'll be called rndis_wlan.
