I have a small device that uses MT7620N:
https://www.anz.ru/files/mediatek/MT7620_Datasheet.pdf
I want to add a USB functionality, so I'm focused on UPHY0_VRES, UPHY0_PADM, UPHY0_V33A, UPHY0_PADP and UPHY0_V12D.
The UPHY0_PADM and UPHY0_PADP are supposed to be the -data and +data for USB. Seeing that the pins at visual inspection don't lead anywhere, I'd say the the rest of the device don't use it.
The UPHY0_V33A and UPHY0_V12D I think are taken cared of as the supply is 3.3V...
Help understanding how to use the USB in the MT7620
