I bought wr1300 v3 router and now I need to add a usb 3.0 or 2.0 port into my wr1300 v3 router, is it possible ?
I installed openwrt to my wr1300 v3 router so there have software support for usb and I just need to confirm if it's board already have the usb port adding option and dependency circuits ?
I also search the board MT7621AT is support usb 3.0 and 2.0 ports.
Are you talking about the 9 pins in the upper left hand corner of the photo? Those are almost certainly not USB. I'd be willing to guess that they are JTAG.
