Dongle Madness

Hi all, I woke up to peculiar problem today.

I've been using my Macbook Pro (13", 2 USB-C ports) with the much-lauded Hyperdrive dongle ( to do passthrough power, a keyboard, and a 4K monitor through 1 port. It was working great! But I woke up this morning and it's not working!

None of the components are busted -- the dongle works fine with the keyboard on a different computer, and the keyboard works with the Macbook Pro when plugged into a single USB-A to C dongle on the Macbook. The Macbook also charges fine with the power cable plugged directly in.

When I attach the dongle, I get a USB Accessories Disabled warning (Unplug the accessory using too much power to re-enable USB devices)...which makes no sense since the dongle has the power cable attached. I've tried resetting the SMC and NVRAM to no avail. Any suggestions??

Call Hyperdrive customer support is my suggestion. If your laptop is reporting power draw errors, I’d listen to it.
