[Prism54-devel] XG-701 / Medion USB Device

[Heiko Panther]

I've started analyzing the device. Here's what I found.

The device was apparently designed by this company:

I disassmbled and took photos. You can find the photos at 
homepage.mac.com/hpanther/XG-701.tbz

The PCB has 2 big chips, one on each side. There is a metal plate about 
0.9cm * 16.cm, which is an antenna. Next to it, there's an antenna jack. 
There is a 2x2 cm shielded area on both sides, which I did not look 
into, because it's soldered to the PCB.

It is a USB to PCI bridge with an 8051 and 8K ROM. See
http://www.netchip.com/products/2280.htm
The bridge is probably loaded with a custom firmware over USB.

Is this device similar to any device which is being worked on currently? Is the bridge used in any device which is being worked on?
