Uno R3 not detected
i have a "Make your own Uno kit", 100% official Uno R3 with a USB-C module, however it is no longer detected at all in Device manager. The power light is on etc. I have looked up and as far as I can see, it is the usb module that needs reset and reloaded in order to get the device detected by device manager again?
However, I don't know how to do that with this, normal R3's have the reset jumpers but this doesnt

yes but nothing gets detected
i can sort of see it
so it looks like that first pin, do i just short it to ground?
this doesnt mention the reset on the module, solely the tiny atmega16u2

it's probably just my soldering then, but it looks ok! it worked, i did nothing with it for a while, and then one day i came back to it but it didnt work.
thanks @WeeGee

i have double checked u2 and q1, they are installed correctly, and i'm getting 4.6 something volts on the 5v rail
4.6v sounds like a diode drop between 5v Vusb and 5v
