Original Question:
It seems like A4tech Mini Keyboards have small issues on Hackintosh / macOS itself. I have the following keyboards which stops working after my hackintosh starts:
- A4tech KLS-5 Mini Wired Keyboard
- A4tech FK11 Fstyler Mini Wired Keyboard
All of my computer USB ports and peripherals (e.g. Gaming Mouse, Flash Drive, USB Powered Speakers) using them are working just fine. I have
- fixed AMD CPU Power Management,
- mapped USB,
- installed USBX, and
- Booting without USB.
To make my keyboard work, I have to plug-out-&-in and wait for a couple of seconds.
Please let me (and others) know if you know how to resolve the issue. Thanks!
