If red light is flashing, it indicates enumeration is failing. Try a different cable or adding/removing a USB hub from the chain.

Operates at a faster rate, say 480 Mbps vs 12 Mbps, and then the cable quality/performance becomes much more of an issue..

The upgrade cannot break the cable.

Just because something "works" doesn't mean there are no issues.
