[Guide] Creating a Custom SSDT for USBInjectAll.kext

Well, this patch can’t give me desired result, at least with current DSDTs.
So I decided to try some manual tuning.
I can locate at least webcam description, and there is no _PRW inside of it, no _PRW inside of port description it is assigned, but there is _PRW inside of hub description, which contains this port.

I want to try add _PRW into webcam description (WCAM or CAM0 device), maybe that can solve instant wake problem?
Or it is unreasonable and stupid?

Well, then I have the last question about USB.
I noticed, that the only USB 2.0 port (HP22 on EHC2) is... lagging???
If I connect my mouse to that USB port, it stops moving for a fraction of a second, which is so annoying... And that problem is definitely not related to my mouse, I've tested it on my old one, the problem is actual for it too.

Not related to USBInjectAll.kext.

Is that a know problem? Does it have a know solution?

Maybe you can suggest something, after taking a look on my DSDT and IOReg data?

The files you attached earlier show nothing connected to HP22.

I don't think adding _PRW for your webcam will help.

I don't see why not. Intel xHCI on 7-series chipset is natively supported.

I have no idea what you're trying to say.
Please spend the time to write coherent English questions.

It is possible the OEM (Fujitsu in this case) decided not to provide any USB3 ports in the chassis, even though the chipset has the capability.

Seems rather unlikely though, and if true, not so smart of the OEM.
 
thanks for answer
