I am not sure if this is the correct place to ask this question. Please tell me off in your usual manner if I am completely off-topic.
On my Lenovo Yoga 710-15IKB, I have a weird problem with any wireless keyboard and mouse, which has a USB receiver. The mouse movement is very erratic and all over the place, hard to control with any kind of precision. The behaviour is similar to when you use the mouse from very far away from the receiver. The problem becomes even more pronounced when there is a device connected to the second USB port, like an external hard disk. (The laptop has only 2 USB 3.0 ports). Especially, when there is any kind of heavy data transfer happening on the external hard disk, the mouse becomes virtually uncontrollable, and the keyboard does not register some keypresses. The built-in touch pad and keyboard work fine.
I have tried swapping the USB port to which the devices are connected. I have tried installing brand new Duracell batteries in the mouse and keyboard. It has not helped.
The problem is NOT there on Windows.
This made me suspect that the current output of the USB ports may be limited on Mac. I thought that maybe the USB receiver is not getting enough current from the USB port.
Yesterday, I implemented the steps in this thread's guide. I already had the SSDT-UIAC.dsl. I think I have done everything related to USB which is recommended by you.
But the problem is still there. Could you please tell me what could be the problem?
