Hello all, I've run into a real headache here. 
To start off, here's my specs Intel Pentium G4560 (no overclock) ASRock B250M-HDV 8GB DDR3 2133MHz Nvidia OEM GTX 760 ti (no overclock) 240GB Samsung SSD 850 EVO (boot and games) 1TB WD Black HDD (main storage) 2TB WD Blue HDD (File History) Seasonic M12ii 520W Bronze EVO Edition Nothing overheats.
May 27, 2017 How to connect to a terminal to Serial-USB device on Ubuntu. PL2303 Serial Port Device Descriptor: bLength 18 bDescriptorType 1 $ tail varlog.
I can run AIDA64 System Stability test for hours without issue and real world use also confirms that nothing goes above 70C. Now here's my headache: Seemingly without reason, rhyme or rhythm, I'll get a message from the Action Center telling me that a USB device has malfunctioned and wasn't recognized.
I've tried restarting the PC without any USB devices connected (not even mouse/KB), and I still got the error after it ran for a few minutes. Strangely enough, it seemed to wait until well after everything startup related had finished and the system had calmed down to idle before giving the error. So that means it's not an external USB device, right?
I don't have any USB controller cards or anything to add extra ports, so I would imagine that it's something on the motherboard. Here is the information I've found from Device Manager regarding the 'malfunctioning' device: General Tab Device Type. USB ROOT_HUB30&VID8086&PIDA2AF&REV0000 USB ROOT_HUB30&VID8086&PIDA2AF USB ROOT_HUB30When I Googled these, I got multiple results and wasn't sure what to go with. I don't know if new drivers will solve my issue or not. Also, I've tried turning off Windows Power Management bullcrap for these devices by not allowing USB power savings in Choose A Power Plan, and I've unchecked 'Allow the computer to turn off this device to save power' in the Power Management tab for the devices who's IDs are listed above. Any and all advice is welcome.
Thank you in advance, Darren. The only other physical thing I can think of is to carefully inspect the rear panel ports for damage whereby a connector is grounding, etc. I've also seen the USB header leads pulled off the motherboard rear panels. The only software thing I can think of it to simply uninstall all the USB devices under device manager and allow them to re detect. Okay well all of the ports work fine when I plug different types of devices into them. And the USB 3 ports do operate at USB 3 speeds.
Through figuring out the syntax of a hardware ID, I was able to find the name of one of my Controllers. I'm gonna go with Intel® USB 3.0 eXtensible Host Controller Driver 5.0.4.43. Currently I'm running a Microsoft driver called USBXHCI.sys. I'm working on finding drivers from Intel for my other controller.
It's just that the website takes some getting used to and I'm still having to look at cheat sheets to pull the info I need out of hardware IDs.
Computer Interface Cable - Driver Installation Repair This guide assumes you have already attempted installation of the USB driver supplied with the computer interface cable. If not, follow the instructions supplied with the computer interface cable.
This guide should be referenced only if you are experiencing a driver installation failure. To the support page.
