Hi all,
I had exactly the same problem. The card would drive a mouse without a problem but no wau to make it work with the mouse AND the GPS receiver...
Too bad

Matt, I also have the USB 2 card and have no trouble with the small optical mouse plugged into it and no external supply. I have also used it with the flash drive without a problem. I have not tried any hard drives with it.

From what I gather, those cards will work without external power BUT will only work in low power mode (so they'll run cardreaders, flashdrives, webcams, digicams, mice/keyboards, etc.). However, they won't power an (unpowered) external hard drive, battery charger or the like, presumably
because the PCMCIA port can't be relied on to supply the current (500mA x 2 plus whatever the card itself draws). This has certainly been the case with the 2 USB2.0 and 2 Firewire cards I've tried (that is, the firewire works in 'unpowered' mode as well but not high power when it needs an extra 12v supply).
Of course, you could always do the trick I did and tap 5v off the motherboard (remember, my L100 has an extra PS/2 port added to the side ;-P ) ... see www.raybot.net for instructions :-)
Cheers!
