There used to be a useful utility called USBProber for OS X, but I can no longer locate it. I am assuming it has been replaced by another utility, but I am not sure what Apple replaced it with or where I can find it.

The last time USBProber worked was with OS X 10.9 and I need the replacement that will work with 10.11 (El Capitan).

USBProber required a kernel extension to function correctly and as the README stated:

IMPORTANT: If the incorrect version of the IOUSBFamily kernel extension is installed, the system may panic on startup. Verify that you are installing this release of the IOUSBFamily to the matching version of OS X.

According to this answer it is not a standard part of Xcode:

Search for iOUSBFamily and download the latest version on the developer page

Installing the package is not recommended as it will overwrite your installed kernel extension, and can cause kernel panics at startup if the version downloaded does not match the OS.

  • Updated my question to make it clear that I am looking for a replacement that will work with 10.11 (El Capitan)
