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

Question

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 spec packets. On a windows computer, I have a working program using hid.dll, but as far as I have researched, there is no equivalent on CE. I know there is the usbhid.dll, 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#. Has anyone had experience consuming an HID device on Windows CE?

Answer 1

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.

Answer 2

Toradex released their USB Sensors and Peripherals into Open Source. The Sensors are HID devices and the free available source code does include samples for C# and VB on Win CE.
