Kimberly Posted November 28, 2016 Posted November 28, 2016 I was using usb otg(microusb) as host mode in kernel 3.x. I was using this port to connect banana pi to touch&PWR in LCD. With kernel 3.x, there was no problem, but in the kernel 4.x the touch did not work. I was searching about the structure of usb port, and found out that to use micro usb as a host mode, the forth pin(sense) and the fifth pin(GND) should be connected. I checked this had been causing a touch problem by trying soldering the forth and the fifth pin of the usb otg port in banana pi, and the touch worked. Isn't there any way I can handle this situation in software-wise, not by soldering? I had also considered buying a microusb wire which has a host end and the slave end, but it seemed quite expensive, so concluded I should either make the micro usb wire by myself or find a software-solution. So basically, I just need to connect the forth with ground. Maybe I can put the GND gpio for the forth pin.... but I don't know how I can do this....
