Troubleshooting SiLabs Driver on Mac notes

tl;dr:

  • 99% chance it's a USB cable problem.
  • If you're a manufacturer, blah blah major and minor device numbers

Looking for this device;

  • /dev/SLAB_USBtoUART

Do you have the driver software installed?

  • find /Library/Extensions/SiLabsUSBDriver.kext

Is the driver loaded?

  • kextstat | grep -i silabs

Loadin the driver:

  • sudo kextload /Library/Extensions/SiLabsUSBDriver.kext

This does something:

  • ioreg -p IOUSB -l

watch console.app and plug device in.
