Every motherboard is different. A USB port map for a Gigabyte Z790 is completely incompatible with an ASUS B660. If you download a random USBPorts.kext from a forum, you will likely lose all USB functionality (including your keyboard and mouse) or cause kernel panics.
Searching for a download is the wrong first step. While you might find a repository with a USBPorts.kext for a motherboard similar to yours, using it is a gamble that almost never pays off. The kext is tied to the used at its creation. If you change your System Definition, your USBPorts.kext will immediately stop working.
You may have exceeded the 15-port limit. Ensure you are removing unnecessary USB 2.0 companions for 3.0 ports.
Remove USBInjectAll.kext if you were using it. Reboot: Restart your computer. Troubleshooting USBPort Issues
USBPorts.kext Download & Mapping: The Complete Guide to Fix Hackintosh USB usbports.kext download
In your OpenCore config.plist , navigate to Kernel -> Quirks and set XhciPortLimit to True . (Note: This quirk may not work reliably on macOS Big Sur 11.3 or newer; if you are on a newer macOS version, it is highly recommended to perform the mapping process on macOS Catalina or older if possible, or use Windows-based mapping tools).
Remove the ports you are not using (e.g., internal headers that are unused) to stay under the 15-port limit.
In the Hackintosh world, USB mapping is a critical post-install step to ensure system stability, proper sleep/wake functions, and high-speed data transfers. Why You Can't Simply "Download" a Generic USBPorts.kext
Plug the USB 2.0 device into every single physical port on your computer. Wait a few seconds for the port to light up green in Hackintool, then unplug it. Repeat the exact same process with the USB 3.0 device. Every motherboard is different
In all other cases, . The 20 minutes you invest will save you hours of troubleshooting later.
The tool will output a fresh, custom USBPorts.kext (or UTBMap.kext ) file.
Any port that did not light up green during your testing is an unused port and must be removed to stay under the 15-port limit.
Click the icon to wipe the list, then click the “refresh” (circular arrow) icon to populate it only with ports that macOS currently detects. Searching for a download is the wrong first step
Click the (Arrow pointing out of a box icon) at the bottom of the Hackintool window.

| Problem | Likely Cause | Solution | |---|---|---| | | You mapped the HSxx port but forgot the companion SSxx port for that physical connector | Re‑run the mapping process. Ensure both the USB 2.0 and USB 3.0 halves of each port are set to connector type 3 | | System randomly wakes from sleep, or fails to wake | An internal device (Bluetooth, webcam) was mapped as external (type 0 ) instead of internal (type 255 ) | Edit your USBPorts.kext (right‑click → Show Package Contents → Contents/Info.plist). Change the connector type for the affected port to 255 | | USB‑C devices work in only one orientation | You chose connector type 10 (no switch) when the hardware actually has a switch | Change the Type‑C port’s connector type from 10 to 9 (or vice versa) | | USBPorts.kext worked on an older macOS version but fails after an upgrade | macOS updates sometimes change USB controller behaviour or require a new mapping format | Regenerate USBPorts.kext using the latest version of Hackintool (v4.1.4 or v4.1.5) while the older map is still active | | Kernel panic on boot | Conflicting USB kexts; or XhciPortLimit is enabled while using a custom map | Check your config.plist for leftover USB injection kexts. Disable XhciPortLimit | | Bluetooth not working | The internal Bluetooth USB port was not included in the map, or its connector type is incorrect | Run the mapping process again, insert a USB 2.0 device into the internal header if possible, or manually add the port by examining your motherboard manual |
