Tichell-
I have been away from home since Christmas and have only now had a chance to begin to play properly with my ME1.
After trying things out, I was annoyed to find that although the Belkin dongle has the correct chipset, and in theory should work, it does NOT seem to work with my ME1. I have now also just bought a Micronet SP907GK V6 (same chipset) which
does work as reported by others here.
Both dongles work fine in my Window laptop, and they both use the same XP driver. I can only guess that the Linux operating system in the ME1 is more fussy about USB device identification. The Micronet shows as a RTL8187B device, but the Belkin as 'Belkin wireless G usb adapter'. Here are my two dongles side by side.

At first I did not think that the Micronet dongle was going to work either because the ME1 reported that it couldn't see any SSIDs, although it was in the same room as my wireless router. But when I manually entered my SSID (and password) it connected (hooray!). If your router has a 'pairing' button you will probably also need to press it for the ME1 to be able to connect.
The led on the dongle is on continuously with no flasing for data transfer once it has been recognised by the ME1 -even when the ME1 is on standby (front light at red). -Not good for energy saving... Seems to me it would also be useful to be able to turn off the ME1 hard drive when you are just streaming from other network drives...
Anyhow, hope this helps... Good luck.
