The USB device remains disconnected.
The USB device remains disconnected.
Your computer frequently loses connection with USB devices. All peripherals like your keyboard, mouse, phone, case fans, and monitor are working intermittently. You tried lowering graphics settings, checking CPU and GPU temps, memory usage, powering off the PC, and even changed the keyboard connection to the monitor. That resolved the keyboard issue. You suspect a chipset problem and confirmed drivers are current. Are there other potential causes you should investigate?
Check a live Linux installation from a memory stick, such as Ubuntu. Verify if the same problem appears in that environment. If it does, it points to a hardware fault with the controller or USB devices. If not, the issue is probably software-related. Also, disconnect all USB devices—both external and internal—and test one by one to identify which one is faulty.
What’s your model, by the way? I had something like this on my old Asrock B350 a while back. A few years in, some of the USB ports—especially those linked to one of the controllers—began supplying less power to connected devices. Devices that needed a lot of energy, like backlit keyboards, hard drives, and webcams, would get stuck in a cycle of connecting and disconnecting. Lower-power devices like USB sticks worked but would sometimes drop out unexpectedly. Could you recall the first time this happened? In my experience, it was likely the external optical drive. The ports seemed to complain right away when I inserted a disk and tried to spin it up. Probably it pulled too much current, damaging the controller. As @whispous suggested, check the ports outside Windows to see if it’s a software issue. Hopefully you’ll still be able to boot and write to the USB stick. In my case, the main front USB ports and the back USB ports on the case functioned fine while the others failed.
Zen2 and Zen3 are CPU models from the Zen series, commonly used in gaming consoles.
The 5600G uses Zen3, combining chipset and CPU aspects. Raising VDDP and VSOC voltages doesn't resolve the issue.
Absolutely, understood. I'll give it a shot and let you know the outcome.
