the result list of HIDManager.GetDevices(false or true) does not return the complete list. I have 3 USB devices attached to my PC
HP Fingerprint sensor
Garmin ForeRunner 305
USB Memory Stick (Intenseo)

The result list only contains the Fingerprint sensor. The others are missing
Used in C#/Visual Studio 2008

Ok, I guess the problem is that the HIDLib is limited to human interface devices. The Garmin and the memory stick don't fit into this category. Guess I have to search for another library then... however, thanks for sharing your work with the public....

Yes, the library is only currently designed to work with HID-class devices. We may extend that in the future if the need arises, but there aren't specific plans to do so at this time.

You're quite welcome - we hope you and others find some good uses for it!

I hadn't replied yet to the original message because I was looking into the details for that model of Garmin - most GPS devices we've played with do use the HID interface, so I'm a bit surprised that the ForeRunner 305 isn't.
