USB lockups Fine Offset 3080, solved by shielding USB cable (?)
Posted: Tue 23 Jan 2018 5:21 am
(Cumulus MX, RPI-3, common connections with 1A adapter, standard USB cable)
Lockups did occur every two till four weeks.
Replacing the USB cable with another one did not help.
Attaching ferrite cores on both ends of the USB cable did not help.
Then I decided to shield the original USB cable, on the outside, with common household aluminium foil. Wrapped some common sellotape around it, to keep the foil in place (rather ugly, but hey, it’s a prototype).
Now, 7 weeks later, still no USB lockup.
A bit early to say, but it looks like this works, at least with my setup.
