xchrisfox28 Posted October 23, 2009 Share Posted October 23, 2009 After installing this on my laptop, I got rid of it (AR9285 support is lacking, and so is HD4530) Decided to put it on an older Emachines desktop of mine, had to change the jumper settings to get it to go past the waiting for root device error, and alas I arrive at the install screen and no USB mouse support. The are my options for keyboards/mouses PS/2 keyboard, USB mouse, or Wireless USB mouse and keyboard. Don't have a PS/2 mouse, wish I did for install at least. Any ideas? & If I get a PS/2 mouse and can install is it possible to use a USB mouse after? Thanks! Anyone?

vilpostus Posted October 23, 2009 Share Posted October 23, 2009 Try changing USB legacy mode in BIOS. Usually OS X do not support PS/2 devices, but DO support USB devices.

xchrisfox28 Posted October 23, 2009 Author Share Posted October 23, 2009 Try changing USB legacy mode in BIOS. Usually OS X do not support PS/2 devices, but DO support USB devices. I tried switching USB legacy mode from On to OFF, and it allowed me to boot, but now mouse, found a PS/2 mouse and that worked with the PS/2 keyboard. I'd much prefer USB to work though. I have to turn USB entirely off in BIOS so I can't use any USB things. Any other thoughts? Thanks!

vilpostus Posted October 24, 2009 Share Posted October 24, 2009 Use both USB mouse and keyboard or both PS/2 mouse and keyboard. Do not mix them.
