The PICs with USB support are clients, not hosts sadly. And they only have one 
port, I think.

So you'd have to implement the whole of USB (ok, just the subset required for 
mass storage and garmin) in software. That'll be hard to fit in the memory of 
a small PIC.

And also you'd have to implement a filesystem, probably FAT16, if you wanted 
anything more than a single long tracklog.

I fear that this would really need a microcontroller big enough to have an 
operating system to do that for you.
