Hello,

I recently got an USB Wifi adapter which appears to be a "Sagem XG76NA" (USB ID is 079b:0062, RF Type is AL2230).


I compiled zd1211rw from http://dsd.object4.net/git/zd1211.git and run it with 2.6.18-mm2 kernel. When I plug the adapter, the following lines appear in dmesg:


usb 1-1: new full speed USB device using uhci_hcd and address 3
usb 1-1: new device found, idVendor=079b, idProduct=0062
usb 1-1: new device strings: Mfr=16, Product=32, SerialNumber=0
usb 1-1: Product: 802.11b/g USB WLAN
usb 1-1: Manufacturer: ZyDAS
usb 1-1: configuration #1 chosen from 1 choice
