defjux23 Posted April 29, 2021 Share Posted April 29, 2021 Hello all! I had a perfectly working Hackintosh using a Radeon VII and the information in my signature. I upgraded to a 6900 XT GPU and now my USB mouse and keyboard skip/are inconsistent. From my limited knowledge, it appears to be due to the USB-C port on the 6900 XT. Is there a way to disable it to have my consistent USB working again? Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Slice Posted April 29, 2021 Share Posted April 29, 2021 I don't think there is an influence. May be IRQ conflict? Are there any related settings in BIOS? Quote Link to comment Share on other sites More sharing options...
defjux23 Posted April 29, 2021 Author Share Posted April 29, 2021 Thank you for the reply. Unfortunately, I don't quite understand your response. From Googling, it appears that two devices can share an IRQ line, but while this can be investigated in Windows, the information can't be found within OS X. Maybe I am totally misunderstanding but your use of IRQ is the first time for me hearing it. I can inspect the BIOS, but I would not be sure what I am looking to change. If it means anything, when I run in the computer in Windows 10, the same USB devices connected in the same ways work perfectly. Thanks again!

Slice Posted April 30, 2021 Share Posted April 30, 2021 Is the CSM disabled in your BIOS? About IRQ you should investigate your DSDT. I have an advice for Clover but not OpenCore. Quote Link to comment Share on other sites More sharing options...
defjux23 Posted April 30, 2021 Author Share Posted April 30, 2021 I remapped my USB ports and that seemed to solve the problem! I appreciate the assistance. Quote Link to comment Share on other sites More sharing options...
