Has anyone ever resolved? I’m having the same issue 4 years later

i can understand the USB Type B port not being soldered correctly there.

but that sticker ?? Hmmm
so.. the sticker was stuck over the top of the where the USB Jack was supposed to be.. is that correct

Very interesting, considering that this is literally the only way to power the device.
and clearly the sticker has been placed there intentionally.

was this perhaps a test model that the customer obtained ?

also
it suprises me that you could not easily find a USB Type B Port.
Couldn't you just go to your local electronics supplier and buy one for a few dollars
or pretty much any device, Printer, Fax, Audio Equipment, Keyboard, MIDI, Modems, Routers, Switches, and the lost goes on..... Pretty much any of these will have this Port on the PCB
then you have DVD players sometimes, Satellite Set Top Boxes
it just goes on and on and on and on and on.... and on

i'm suprised you had trouble finding it

but hey.. in the end
it was a success. so cool.
good job

Nice job. Sometimes you know about the part but when you look for its substitute it is hard to find. But thanks for sharing this article.
