3.1內(nèi)核，啟動(dòng)后，有/dev/usb/hiddev0設(shè)備
cat /dev/usb/hiddev0，然后觸摸屏，打印以下錯(cuò)誤：

怎么解決這個(gè)問(wèn)題。屏的信息如下：

1. Udevadm info starts with the device specified by the devpath and then
   
2. walks up the chain of parent devices. It prints for every device
   
3. found, all possible attributes in the udev rules key format.
   
4. A rule to match, can be composed by the attributes of the device
   
5. and the attributes from one single parent device.
