I've seen for a while the list of supported cards. I've noticed my cards
was'nt /apparently/ listed (ZCom XG-703a). But a line was interesting :
Card: Sagem USB XG703A
Another manufacturer, but same designation. After some research, I found
it is the same usb dongle hardware. So, we can say that ZCom XG703A is
supported by ndiswrapper, and needed drivers are the same as Sagem
Hope it will help you.
