"Unidentified USB Device" on Win CE 6.0

Quite a while I am struggling with a problem regarding the installation of certain USB device driver in Windows CE 6.0.

The device is some kind of Digital and Analog IO device that connects to the USB port. It is the LabJack U3.

I followed all instruction and put the driver (labjackusb.dll) and coresponding registry entries into the Windows CE image but the device is not detected correctly.

On every boot up a small Message box came up with the Title "Unidentified USB Device" and the message "Enter the name of the driver for this USB device:"

Whatever name I put into it want work. I tried the name of the dll. Some title in from the registry and so on but never succedes.

The driver does not work nor the device.

The customer support can not help me so I am asking here somebody to help me at least with a steps to follow to try to find a solution.

Why the OS does not matches the USB device with the corresponding driver? I checked everything one million times and everything is in place.

There are a load of reasons this might fail. First:

  • Is the driver definitely a Windows CE driver?
  • Is it built for CE 6.0 (not 5.0 or something else)?
  • Is it built for the same processor architecture you have?

The way to really debug this is to hook up KITL, put in a debug version of device.exe and see what the device managet is actually doing when you plug in the device. A way better and way more reliable mechanism than just trying to guess.
