Dear all:

I have a usb touch device, I can update the hid report descriptor of it.

 

There are two hid report descriptors.

one with status, x, y, I call it A descriptor.

one with status, x, y, pressure, I call it B descriptor.

 

When I using touch device with A, it works fine.

If I use touch device with B, the WINCE 7 os will reset the device.

 

I test the usb touch device on windows 7, both of them works fine.

So I can make sure the firmware of the device is ok.

 

I trace the source code of imx 51 BSP under

\platform\common\src\soc\COMMON_FSL_V3\MS\USBH\USB2COM.

The detach is from CFunction::HandleDetach, but I still unknow what happen.

 

 

Does any one know about this situation?

 

 

Thanks for your help.
