I use the same router.
As far as I see all needed kernel modules installed.
Probably it can be a hardware problem or modules didn't load by any other means.
Try this

  1. lsmod. USB modules loaded?
  2. dmesg | grep USB. Or dmesg and manually look for entries after registered new device you must find new xHCI controller init and USB hub init.
    Probably you can find some information there.
    Additionally cat /proc/devices must show usb device

Thanks for your answer and sorry for my slow response

Also I used USB stick as expansion for root partition on this device for half a year, but system stopped recognise it after factory reset or system upgrade (not sure, it was a lot time ago)
