Mac Yosemite USB to DVI Adapter not working
Today I upgraded to Mac OS Yosemite and my tiny little Cable Matters USB3-to-DVI Adapter stopped working.
If you can still find the device in „About my Mac“ then its the driver, not the hardware.
Cable Matters does not offer a Yosemite driver, but the original device manufacturer does: DisplayLink. Get the updated driver on their support website.
Install, reboot. Everything fine.
