garmin has changed its communication protocol when they switched
from rs232 to usb, dropping checksums handshakes etc.
my driver can operate in both protocol modes. It can translate
the garmin older serial protocol into the new usb package format, so 
from userspace it can behave the same as an pre-usb gps receiver 
connected to a serial port, existing software must not be changed to
use the usb bus.

btw. i think i have addressed all your points regarding my last
patch, i will do some more testing today and send you a new
patch by tomorrow.
