I have forcedly installed merlinwrt on DSL edition of AC68U (don't judge me for bad purchase choices), of course I lost DSL functionality but that's ok because I have another modem, and I routed my DSL connection through WAN. Everything works perfectly, except USB port. As you know, RT model has 2 USB ports whereas DSL model has 1 USB3 port. Basically xhci hub is not even initialized, so there is no activity in the logs when I plug a USB device, nothing at all. But I assume this is an easy fix that just requires me to map/init the USB ports according to DSL version, comparing with the original source. Merlin, do you know where I should look at? I know you don't support DSL models. I just need guidance, that's it. Everything else works, it's just the initialization of USB hub. Thanks for the help.
