Original Question:
Hi everyone I have a problem with a USB card.
I use the addition to the USB of on my motherboard another USB PCie card
And I have a problem while shutting down and sleeping. If something is connected to this card and I try to go into sleep mode then after a few seconds it wakes up and when I turn off the computer then it shuts down and then after a few seconds it turns on again.
Besides everything is fine, everything works for me and works really well only this problem I currently have, and I really want to use this USB card in MacOS.
It does work and detects USB 3 and USB 2 without issue.
In System Report this is the information about it:
Host Controller Driver: AppleUSBXHCIPCI
PCI Device ID: 0x3483
PCI Revision ID: 0x0001
PCI Vendor ID: 0x1106
I have Kext for USB mapping (I took from my friend who has the same motherboard)
CPU: i5 7600k
Motherboard: GA-Z270X-Ultra-Gaming
RAM: 16GB
GPU: GT710 + iGPU
If you need more information that I did not mention here I will add just say what is needed.
Thanks in advance.
