Hello!
I need a router for 10G networking and CCR2116-12G-4S+ seems like the best choice for me in terms of IO and performance.
It has almost everything I need (a couple more SFP+ would be nice, but you can't have everything I guess), but it doesn't have any USB ports.
It has an M.2 slot inside with four PCIe lanes connected... And I wonder, does RouterOS support some PCIe USB controllers, so I could just jank some USB controller into the internal M.2 slot?
I can't think about any hardware reason for this to not work, I could even design my own "M.2 to standard PCIe connector" adapter that would fit in there, but does the OS allow something like this?
