Recapping my parts of it - on my 14 month old Vero V:
my remote is not responding at all - repairing has the blue light on for 30 seconds
my external USB2 port seems to be working fine
my USB3 port has power, but loses it if I jiggle my USB power meter in it a bit
I may have had my longish TV tuner plugged into the USB3 port at times, so perhaps that has applied too much torque to it.
Would it be appropriate to open up the Vero V, resolder the USB3 port, and inspect the board under a microscope looking for cracks/dry joints etc? If so, are there any guides to disassembling the V, or any tips?
So I was answering your question and saying yes, the USB3 does have power - but it appeared to be intermittent. That it went away when I moved the USB power meter made me suspect cracks on the board…? And yes, reseating the remote dongle might indeed be the fix for that (not that I recall any rough treatment of the V that could have dislodged the dongle) - but presumably it wouldn’t explain the tenuous power connection for the USB3 port.
Given the above, my best idea was to open things up and have a look - but if you’ve better ideas on how to proceed, trust me I’m all ears thanks!
I opened it up, and had a friend who designs PCBs etc look at it under a microscope. He poked at each pad on the USB connectors but saw no movement/signs of cracked joints - nor any fried chips, so we didn’t bother reflowing the solder. There was nothing obviously wrong inside.
the remote dongle was very solidly seated in the internal USB2 port. I removed it, and it works fine in the outer USB2 port.
the USB3 power drop outs I saw when wiggling my power meter appear to be simply because the USB3 port is a bit recessed, the power meter is deep from top to bottom, and the case overhangs somewhat at the top. So twisting the power meter upwards simply levers it out from the socket.
Unless you’ve a better idea I guess I’ll just buy a powered USB2 hub and use that in the one remaining USB2 port. Unless, perhaps, the white 4 pin connector on the circuit board is another USB port I could possibly connect up and put a lead out of the case?
Thanks Sam. If that yields little, I could resurrect my 4K+ and send my V back for inspection too - I guess I’d lose access to some more recent AV1 media, and postage from Australia won’t be cheap, but sating curiosity has plenty of value too. (Truth be told it’s not like I needed the V, it was mainly about supporting you guys, whilst getting some slightly snappier menus)
I think I might have the same problem: Vero V bought ~18 months ago. USB3.0 port had an external HDD plugged in permanently, mount disappeared a couple of days ago. Output of lsusb wouldn’t show the disk anymore. Plugging the HDD in the USB2 port - disk shows up again. Other devices also don’t show up when connected to USB3.0, but when connected to USB2 port.
