Hi, I'm new to odroid.... i bought a odroid C2, and installed odroid's ubuntu mate. Straight away, the keyboard would disappear .... 5 or 6 minutes, it would flash and then no response. the only way to get it back was to reboot. Following a recomendation, I rebuilt with armbian last night. I'm still having the same problems. I've tried the k/b on the usb ports as well as the otg...both the same. Following a suggestion, I tried using an old usb1.1 hub...still the same. If anyone has any suggestions.... Thanks in advance Terry
