Which look very much like typical USB communication problems:

The usual advice applies:

A cable with ferrite cores on both ends, bought from a reputable supplier (rather than a randomly named Amazon / eBay seller who also offers beach attire and kitchen utensils), seems to resolve many problems. IMO it’s because the ferrite cores justify a price high enough to allow better (or any) QC for the internal wiring.

However, this suggest a different problem:

Power supply problems can be caused by a loose / slightly unplugged connector, so be certain all the electrical connections are solidly plugged in and not wiggly loose.

The symptoms suggest getting a better cable, because that’s relatively cheap and easy.

If the problems continue and, in particular, if the power supply error occurs again, then a new power supply is likely to help.

You’re in the right place with the right questions. IMO, a fair number of young pups are doing much worse. :grin:
