Initial data: There are two android tv consoles, both on android 6 and the Asus touchscreen monitor, which tach works through the usbhid kernel module. Same architecture armv8l, the same versions of 3.14.29 cores, but different android assemblies Also differ in processors: s912 ) and s905x (X96)
The essence of the problem: On one set-top box, the touchscreen starts up normally and works out of the box, on the other - not
The first console (on s905x):
After connecting usb touchscreen, the kernel says the following:
usb 1-2: new full-speed USB device number 3 using xhci-hcd input: ILITEK ILITEK Multi-Touch as /devices/c9000000.dwc3/xhci-hcd.0.auto/usb1/1-2/1-2:1.0/0003:222A:0045.0003/input/input5 hid-multitouch 0003:222A:0045.0003: input,hiddev0: USB HID v1.10 Device [ILITEK ILITEK Multi-Touch] on usb-xhci-hcd.0.auto-2/input0 Next, the devices are created in / dev and everything works:
root@p212:/ # ls /dev/usb/ hiddev0 input1-1:1.0 usbmisc1-1:1.0 The second prefix:
After connecting usb touchscreen, the kernel says only the following and nothing more:
usb 1-2: new full-speed USB device number 3 using xhci-hcd In / dev / usb, respectively, is empty, the touch does not work
In both cases, when connecting to / sys / bus / usb / devices /, a new device appears and it can be seen that it works under the usbhid driver. Also, on both consoles identical lsusb pins
Bus 001 Device 003: ID 222a:0045 Please tell me which way to dig, where there may be a problem with the second prefix.
