All USB asics get HW errors, 388 each on a row of 6 in 6days runnin.
Some are real (affect shift) most are fake and should be ignored.
5 errors in 2500 good accepts is not bad.
CPU and GPU I had no errors ever.
USB well they all do that, it is when 1 shows way more than the others, or like 200 in the first few mins, ya got a problem. usually lack of power to hub or incompatible hub. None of the USB stuff like USB 3.0 specs much.
They all adhere to USB 1.1 and 2.0 using 1.1 speeds to talk to bus.
