One particular external hard drive won't connect as USB 3

Hey all,

Trying to troubleshoot a weird problem. I have 3 external USB 3 hard drives. 2 of them work fine as USB 3. 1 of them will ONLY connect as USB 2.

The misbehaving drive connects as USB 3 on my Macbook Pro, so there must be something wrong with my Hackintosh.

I've just been through the stages of installing the USBInjectAll kext and increasing my port limit for High Sierra, but that didn't change anything. (All 3 drives work exactly the same with or without the kext/port limit change. Perhaps I have an old kext overriding it, but I don't know what it could be?)

It's a WD My Passport 1tb if that makes any difference. Any suggestions as to how I could get this blasted this up to USB 3?

Thank you!
