## Intermediate issues with USB 1.1 and Bluetooth on MacPro3,1 - MacPro5,1
For those experiencing issues with USB 1.1 devices (such as mice, keyboards and bluetooth chipsets), macOS Big Sur and newer have weakened OS-side reliability for the UHCI controller in older Mac Pros.
* UHCI is a USB 1.1 controller that is hooked together with the USB 2.0 ports in your system. Whenever a USB 1.1 device is detected, the UHCI controller is given ownership of the device at a hardware/firmware level.
* EHCI is the USB 2.0 controller in older Mac Pros
Because of this, we recommend placing a USB 2.0/3.0 hub between your devices and the port on the Mac Pro. UHCI and EHCI cannot both be used at once, so using a USB hub will always force the EHCI controller on.
* Alternatively, you can try cold starting the hardware and see if macOS recognizes the UHCI controller properly
