Consuming a USB HID device in Windows CE 6.0 using C#

I am working on an embedded Windows CE project and am interested in accessing a USB HID device through one of its USB Host ports. All I really need to read are the raw HID specification packets.

On a Windows computer, I have a working program using hid.dll, but as far as I have researched, there isn't any equivalent on Windows CE. I know there is the usbhid.dll file, but I'm not sure if it is applicable for this situation. I would prefer not to write a kernel level driver, as I would like to do my coding in C#. How can I make consuming an HID device on Windows CE work?

If you have made any headway with this please let me know. I'm about to embark on writing a HiD driver for a bluetooth keyboard on the same platform. Would love a heads up development issues with Win CE as this will be my first ever compact framework development – Dark Star1
Any progress with this? I'm trying to do the exact thing , but i cannot see the usb device as an serial port . – Gabriel
Unfortunately I didn't have much luck with this project, so I can't help very much. Sorry. – kersny

I have no concrete experience with HID, but accessing the USB port as a COM port with a proper driver DLL (the device manufacturer might have one) might help. Theoretically you should be able to receive the device's raw data packets with a SerialPort class that way.

Toradex released their USB sensors and peripherals as open source.

The sensors are HID devices and the freely available source code does include samples for C# and Visual Basic on Windows CE.
