Try cloning \PUBLIC\COMMON\OAK\DRIVERS\USB and add a Sleep(10) to the
beginning of the function CHW::EnterOperationalState in chw.cpp.
At the cloning make sure you change all the sources files to link the
right libs (now build in _TARGETPLATROOT).
Good luck,

I already tried it. But I couldn't find any clue from it. And curiously, the touch driver was loaded at boot time. But it didn't work..

It is probably some sort of timing issue. At boot time
the system is busy doing a lot of things, so it might
be possible that the host/client driver is a bit slowly
when enumerating and initializing devices.
Try running debug build and see if you find anything
related in your boot log ...

daniel wrote:hi? I have been using a usb type touch driver without problem. But I could find the touch couldn't work well when the touch module was connected to a usb port from usb hub chipset. To my curious, the touch can work after unplug and re-plug the touch usb cable. And it also work well when I plug the touch's usb cable after completing os booting. Only when it couldn't work is I boot the board with plugging the touch module. And I also tested a usb mass storage device with plugging it to board at boot time. It worked well! Only touch couldn't work at boot time. Is there anybody who give me a hint?
