I see what you mean, just adapter that routes USB pins to USB connector, not actual USB controller. But I don't think these are connected in RB4011, it may only have the PCIe pins connected, not USB.

ROS doesn't have drivers for regular USB controllers, so it will see the pci-e device but will not be able to use it.

First of all make sure you choose right hardware. The Groove is not a good choice, as it's single chain only, right from the start you have half the bandwidth of 2x2 link.

Cheapest solution is to buy used ubiquity gear and use that. Something like M5 bullet with airview sw does everything you need and can be had very cheaply.

Interesting. There doesn't seems to be missing many SMDs around mini-PciE slot, might be fun experiment to solder it in and see if it actually works. It may as it just needs power and pci-e lanes that should be coming directly from CPU.

This could be very useful to pull custom data from SFPs.

NV2 is proprietary to Mikrotik, so you can't use any other hardware.

"port - removed serial console port on hEX S" this is real shame (Why Mikrotik keeps preventing you from recovering devices using UART connection?!), but it ONLY affects on board UART pads. Not WOOBM or USB converters, they are still supported on all hardware with USB ports.

This should work, you are not doing anything wrong. Mikrotik can see the serial port but for some reason doesn't want to enable console on it... this never happened to me.

Then go to system/console and add console on that port. This will be remembered as long as you plug in same USB adapter to the same USB port.
