usb gps linux/windows

I've been doing a good deal of warwalking and wardriving using my pocketpc and my dualboot laptop. Thus far, I've just been keeping track of where I've been finding the WAPs in my notebook.

I know a lot of tools have the ability to map them via gps.

I'm looking for a good usb (2.0) gps device. I would prefer that it works under both linux and windows. I'm using fedora core 3 (latest kernel with all updates) and Windows xp sp2 with all updates. If I can't find one that works under both OSs, then one for Windows will work just fine. I can map out everything using netstumbler.

Anyone have any experience with usb gps devices and what would you recommend I get?

FYI- I would normally not have a problem using a pcmcia card, but my laptop only has one pcmcia slot in which I'm using a netgear wg511 g/b card.

TIA

Certainly on the british ebay theres been a flood of Cheap GPS units from hong kong, cos like £30, there USB and claim to work under linux and windows, might be an area to investigate

my mates disertation at the moment involves a gps system and he's purchased a £30 gps unit from a company, thats serail based, but its literally the size of a postage stamp, its so cool, just thought id drop that in there

Garmin makes good gps devices that work with linux and windows. Kismet has a built in GPS mapper for linux.

I thought garmin used the serial port?

You could always get a USB to serial adapter I suppose? Ive got one and it works on linux and windows and it cost me under £10, so it could be a cheap alternative, not as neat but never mind
