There are three semicircular and one rectangular cutout on the rear-end of the CA433U case. I read that the rectangular cutout is for USB (which I need). What type of adapter/connector did MikroTik spec that cutout for? Where can I find one? Is there a specification name for that rectangular cutout?
I'm using RBM33G with CA433U case and need to expose the USB port on the CA433U case (with a USB port affixed to the case) so that someone in the field does not have to open the case to plug/unplug USB devices.
