Something I discovered when I updated to the latest MiSTer linux files release_20190206. My 8bitdo USB Adapter (orange brick looking dongle) would interfere with the keyboard. When the adapter was plugged in, it would cause any USB keyboard to cease functioning while adapter was linked with any 8bitdo controller. If you unlink the controller or disconnect the adapter, the keyboard would function normally. I tested the controllers and adapter on a couple of computers and it worked perfectly. At first I updated both my sn30 pro & sfc30 controllers to firmware 4.10 but the issue persisted.
After some trial and error, I updated the USB Adapter from 1.18 firmware to v1.22 and this seems to have corrected the issue.
Just thought I put this out there in case anyone else experiences this problem.
Firmware update did not fix my issue. As Sorgelig mentioned the only thing that makes a difference is trying different USB ports. Sometimes second controller works ok and sometimes very very lagged. Probably in the 1/4 - 1/2 second range.

to me it's just traditional DE10-nano USB host driver issue. Kernel 4.19 (latest Linux release) gives me better compatibility with many ports on HUB used. Changing USB HUB ports usually help. It including changing of other USB devices as well.
