Only if the problem is purely software. I've had reproducible problems that were impossible to solve by myself. The process went like this: - Huh, getting USB disconnects randomly, need to fix this - Hmm, device driver seems to be fine - Hmm usbnet driver seems fine - Hmm xhci driver seem fine - $5000 and one USB 3.0 protocol analyzer later... - What the heck is this host controller doing? At this point it was looking like a hardware problem but seeing as I didn't have the schematics or verilog of the host controller I could go no further (nor did I want too... I never imagined USB could be such a deep rabbit hole).
