Hi
In posts #665 and #681 of the Hackintool thread I mentioned that I have issues with USB3.0 ports that don't work with USB2.0 devices (although they work fine, at full speed, with USB3.0 devices).
In both cases, these are USB ports on the front of the case (Cooltek X5, different units, bought 18 months apart).
(The central USB2.0 port works OK)
Notice how weird it is that one of the USB3.0 ports is labelled as USB3.0 while the USB2.0 port and the other USB3.0 port are both only labelled as USB. Has anyone ever heard of USB3.0 ports that would not be compatible with USB2.0? Or maybe this is just cheap design...
Of course there was zero documentation provided with the cases... nor online...
I connected the USB3.0 header to the USB3.0 connector on the Mobo while I left the pigtail USB2.0 header disconnected.
I intuitively thought this was the right thing to do back then, since I assumed the following:
- USB3.0 is backward compatible with USB2.0
- if both headers needed to be connected the manufacturer would have used separate cables since USB3.0 connectors on some Mobos are nowhere near USB2.0 connectors.
- This post seemed to indicate that connecting both could lead to electrical problems and I didn't want to fry anything
I have the same issue (USB2.0 not working on these USB3.0 ports) on Windows 10 and macOS (mojave). Except when I try to setup the ports with hackingtool (USBinjectAll present, -uia_exclude_ss boot flag present), then they work with USB2.0 devices (so they can work?!?).
I'm wondering if this is a hardware issue (since both headers come from the same model of case) or if I should plug that USB2.0 header somewhere (this is physically possible on my z370-a/z390-a). I don't want to burn the hardware for the sake of this test, though. So I wonder if anyone knows exactly what the risk is here.
Thank you very much in advance for your help or advice.
best,

PS: I know the USB3.0 conector on the Mobo is fine since I tested it with a different USB3.0 header (2x USB3.0, no USB2.0 ports) and both USB3.0 ports worked with USB2.0 devices and USB3.0 devices.
