onemanOSX Posted October 19, 2018 Share Posted October 19, 2018 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.
