I've never seen anything that supports direct access to a USB port. I've
been using a hardware based Serial to USB converter. Works great, cost
under $30 and doubles the serial port baud rate. No software changes
required.

Hi,

ALL GPS devices that I have used that provide USB interfaces actually are
serial port adapters.  Thus, your code needs no change.

I have never seen a USB GPS device that worked in any other fashion, and if
it did, it would not work with any standard applications.

I have done this with a Motorola Cell phone that has a GPS receiver in it.
It actually had a serial driver that would write the data out to a virtual
COM port (COM7 in my case)  and I could read from that just like a regular
serial port.

Hello,

I have a VB6 application that reads and writes simple ascii nmea GPS
sentences to a serial port (Com-n). Since many new GPS devices support USB,
I like to have the option to change this to USB.

But: I have no idea how to achieve this or even where to start.

Can anyone in this group point me into the right direction?

Thanks,
Ger

Thank you all for your replies. They were all very helpful.
I also found a USB SDK on Garmin's website I am going to check out.
