I am having all sorts of problems with this board. I have tried 2 different USB keys.
1st key ZTE MF112, resulted in USB port invalid errors and random reboots
2nd key Huawei E169 USB modem 19 times out of 20 they board doesnt pickup the device after a reboot. I can disconnect the key a 100 times, plug it back in and it wont see it - Also now seeing random reboots
Only time I can get it to pick it up on random occasions is a power off for 10+ min or doing a fimrware upgrade or downgrade.
I have tried firmware 5.1 and 4.17
Is there any way of getting this to work and remain stable? I cant afford to keep on buying these keys
