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 ...

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?.
