PROBLEM: Identified a USB 3.0 Cable likely either going bad or out-of-
specifications, and now only compatible with USB 2.0.
Cable Matters SuperSpeed USB 3.0 Type A to B Cable in Black 10 Feet
Item model number : 200007-BLACK-10
Date First Available : October 20, 2011
Manufacturer : Cable Matters
ASIN : B00C7RZPJ0
SCENARIO: The ten foot USB 3.0 rated cable is connecting from the
motherboard USB-3 port to the display included USB-3 rated hub, with two
USB-2 peripheral input devices connect to the USB display hub. Although
connected through the #1 USB-3 motherboard hub, errors were reporting on
the #2 USB-3 motherboard hub/ports.
SOLUTION: Connect the lengthy ten foot USB-3 cable inhibiting
errors/failures on the motherboard USB-3 hub to a motherboard USB-2 hub.
This newer recently purchased motherboard has USB-3 ports, whereas my
older motherboard had only USB-2 ports. I also noted problems using a
ten foot USB-2 rated cable with a USB printer, plugging into an external
hub and with similar kernel printed errors/failures awhile ago,
subsequently plugging the printer USB cable directly into the computer
motherboard/PCI-E USB hub. NOTE: Probably a good idea for labeling
these ten foot or lengthy cords, with labels noting only for use with
USB-2 ports.
It really baffles to-date that there are no decent front-ends or back-
ends, reporting bad cables and/or connections due to lack of
power/electrical current!
