Usb touch device auto reset with imx 51 evk on wince 7

[謝端桂]

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.

Hi xie

seems usb hid touch driver is not supported by i.mx51 evk wince7 bsp,

refer to attached Linux Manual sect.19.5.8 Class Drivers for supported

drivers. One can add such driver using msdn resources

Msdn forums - Windows Embedded Compact Platform Development

or guidelines for example on

USB HID Touch

Best regards

igor

Hi, igorpadykov

I forgive to tell a information, I don't use the default USB-HID driver of windows embedded compact 7.

I write a usb driver(USBDeviceAttach) for the touch device.

Thank for your help.
