Issues with USB ports and the "USB Controller resources exceeded" alert occur occasionally.
Issues with USB ports and the "USB Controller resources exceeded" alert occur occasionally.
Hello, I see the issue with your PC's USB ports behaving strangely. It seems they sometimes disconnect without any sound and don't work at all, while other times a warning pops up about "USB Controller Resources Exceeded." The problem has been ongoing for a few weeks now. You've already tried checking Device Manager, updating your motherboard BIOS, and running system tools like SFC, DISM, and checking for updates—nothing resolved it. Your system details are noted, but no specific recommendations came through. Could you share more about the other hardware or any recent changes?
Close the USB hub or controller in Device Manager, then restart the PC and try to reinstall.
Hubs: 1, 2
Plugged In Devices: multiple peripherals and hubs connected for testing.
Thanks for your feedback. I've made some progress on the problem. The dongle seems to function properly when connected through a USB-C hub or adapter, but it doesn't work with standard USB ports on my Windows PC. This suggests the issue might be related to how the port is being driven or the specific hardware configuration. I'm investigating further to identify any potential causes.
Hi, I own a Corsair K70 keyboard with a USB passthrough for a Sennheiser BTD 600. My Gigabyte monitor uses a two-port USB hub connected to the PC, which also has my Xbox Elite charging cable and controller dongle. The MOZA R5 Racing wheel is plugged in as well. I've tried disconnecting everything except these items and left the mouse and keyboard in, but some devices still fail to connect. Note: Earlier I mentioned success with a USB-C dongle that works on other ports.
When you boot into BIOS, does your keyboard function through the USB 2 port? If not, it indicates a hardware problem—try using a USB-C adapter or replace the motherboard. If it works with USB-C, the issue likely lies in Windows software. You may need to locate the source of the problem or perform a reinstall. It could also be due to static buildup; test by unplugging the computer, holding the power button for 10 seconds, then reconnecting and restarting. This can reset capacitors and sometimes resolve the issue.
