Failing USB electronics seems symptomatic of corner cutting at the level of pennies per unit. Sure anyone can get a bad batch of chips. It’s what gets done about it that speaks to quality.
This wasn’t rough use by me. It was barely used. It was a manufacturing defect and there is no way that Unicomp could not know after the keyboard was in their shop and unlikely they didn’t know before. You just can’t be in the keyboard business that long and not know what is going on.
They probably made good keyboards for a long time and might again. Mine was poorly made in terms of reliability and I don’t have confidence that they repaired it with more reliable components.
