Hi,

Currently working on an MSI B360 Gaming Arctic (for some reason my signature is not showing my builds).

 

This motherboard has mixture of USB 3.1 gen 1, gen 2 and 2.0 ports. All USB ports are working as well as i can get 5gbps speed. However, in verbose, I noticed these errors and found no joy on how to solve the matter. I have a suspicion it has something to do with the gen 2 speed of 10gbps? But, I do not have the devices to test that speed yet as of now.

 

I also have an additional Asmedia 2 ports USB 3.1 pcie installed if that helps. But the issue is more to XHC@14000000 so I suppose the pcie has no part to play in the error.

 

Appreciate if anyone can guide me to the correct direction to troubleshoot and pin point the area I should be looking at.

 

PS: I can attach more files if requested. But, I am currently not at my hack so I can only upload later in the evening.

 

Thanks in advance.
