I've been having trouble getting my Pinebook Pro's left-hand USB port, the large Type-A one with the blue interior and superspeed pins, to work at all. I can get power from it alright (though no data on whether negotiation is working yet), but nothing I plug into it enumerates or shows up in `lsusb`, nor does `dmesg` show any events. This applies to both USB-2.0-only devices, as well as those that support USB 3.0. The other USB ports - the Type-C one, and the 2.0 Type-A one on the right side, are both working just fine, so I'm suspecting the hardware here. I'm mainly posting this thread to ask if anyone else can confirm that their 3.0 port works, just so we can narrow it down to a spurious defect in my particular unit (one that I, confident with a soldering iron, might repair) or a more general design flaw or firmware bug that needs more professional attention.
So, does your left Type-A USB port work?
