Help identify failing USB

Logs show issues with usb 3-4-port1, but I cannot figure out if this is an onboard USB controller or one of the two hubs I have connected.
I've tried to troubleshoot this by disconnecting each of the two hubs connected one by one, no cigar.

$ sudo dmesg | grep -i "usb 3-4-port1"
[    6.088032] usb 3-4-port1: Cannot enable. Maybe the USB cable is bad?

I then reconnected each USB cable and device attached to the motherboard.

I can't figure out if this error is from the (brand new) motherboard's onboard USB controller that's failing or its really one of the connected USB cables.

Re: Help identify failing USB

It eventually shows up

and then flickers like crazy - google says that's some radio chip, perhaps a dongle, wifi/bt/dvb - that kind of stuff.
