[Solved] External drives no longer showing up?

[sadida17]

Hi guys,

so I've recently upgraded to 10.13.4. I'm not sure if this problem occurs due to the recent update but it might be.

Whenever I plug my external drive into my Hackintosh (via USB 3.0, the only possible connection), it does not mount. It does not show up in disk utility and it doesn't show up in diskutil list. The drive itself is totally fine, I've tried it with my MacBook and even repaired permissions over there.

It's my Time Machine-drive, if that's relevant to know. My last backup was done on March 1st this year, so that's when I could still mount it. Not sure when exactly my Hackintosh changed it's mind

My motherboard is a Gigabyte Z97N WIFI and I installed the latest USBInjectAll.kext.

Any sort of help would be really appreciated!

Hi,

Sounds like a USB 3.0 issue.

USBInjectAll.kext does nothing alone. Please remove the kext.

Hey jamesst20,

sorry for the very late reply on my part and THANK YOU for your Kext-Patch. It works perfectly! I've also deleted USBInjectAll.kext, as you suggested. Again, thank you so much.

Wrong.
Actually, USBInjectAll.kext will inject all USB ports for EHCI and xHCI controllers.

Hi, I've the same problem but with Big Sur on Asus b460m-plus wifi.
I see the external usb but not the external hdd.

Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...
