I can plug in cameras and USB memory drives without any disconnection. However, when I plug in my iPhone into my Macbook Air 2015 it keeps disconnecting and reconnecting as If the USB problems persist, AMD then recommends the motherboard’s PCIe settings be toggled down from PCIe 4.0 to the slower 3.0 interface.

It shows the monitors as connected for 1 second then it disconnects for 5 then repeats that cycle. It was working fine before last night and I thought it started because my Cpu temp may have been pretty warm, but testing it now still has the same issue. 1. USB devices connected to my eGPU (Razer Core X Chroma) USB ports would cut out, but ethernet was fine. USB devices connected to my Thunderbolt 3 hub USB ports would cut out, but monitors were fine. My USB keyboard would ignore the first keystroke after a few minutes of inactivity, and sometimes only a few seconds. If all else failed then factory reset your computer (if you can stomach it) Hope this helps.

If you are able to charge the laptop through the port but are having trouble connecting external devices, it could indicate a hardware problem with the port. One thing you can try is to update the drivers for the USB port. Here is a list of all of my devices: USB 3.0: 7 port self-powered USB 3.1 HUB. Corsair K95 RGB keyboard. Corsair RGB mouse. Logitec webcam. USB 3.0 thumb drive. External hard drive hub that supports two SATA drives and has its own power supply. Contains 1 5400RPM HDD and 1 SSD USB 2.0: dunno if this is the problem with my gigabyte z590 ud ac, but i thought it was because of the xbox wireless adapter i had in a 3.2 port in the back.. but i put it in the port next to it and it works fine, when i put it back in the other port then it doesnt even recognize the device anymore Try using a USB extension cable to move the wireless adapter up and away from the PC. Try using the wireless adapter on another known working computer. Try another known working wireless adapter on your computer. Determine if the problems follow the adapter or stay with your computer. Run "ipconfig /all" via the Command Prompt. Post the results ayw6011.
