Hey.

Relative success with a Ryzentosh build with a Gigabyte B450M DS3H. Everything work on first boot.. and 50% of the time suspend resume works, but otherwise random USB devices stop working. I'm on iMacPro1,1 and the latest OC. with Ethernet only via PowerLine.

I've done a USB mapping via hackingtools and generated a new USB aml map but there are still random failures :(.

It seems like the whole USB stack needs to be reset on resume.. Any ideas?

Thanks!

David

Turns out My Das keyboard is USB3 (but actually has a USB 2.0 hub internally). USB 2.0 plugged into USB 3.0 doesnt work with suspend/wake. It works now!
