Connect-a-desk

OMG OMG OMG!!!

I just discovered the connect-a-desk

I had a crazy idea for something exactly like this a couple of years ago, when I was in Las Vegas for Christmas, in a line for a buffet on Christmas Day, and on call. I was trying to juggle a laptop and deal with something I'd been paged about whilst still standing in line.

I'm so buying one. I could work on a treadmill!

USB power switch?

I bought these USB powered lights from Woot! recently, with grand plans of using them with a continuous build/test/install rig to provide visual notification of when a build/test/install completed or failed or something.

Somewhat to be expected for the price, they merely draw power from the USB port, and have a physical switch on each light. I want something software controlled though.

There's something in /sys/bus/usb/devices/*/power/level that looked promising, but seems to be a red-herring (at least for non-devices. I was able to turn off a USB mouse and a Bluetooth adapter this way)

What I'd like (and it probably exists, I just have to find it), is a USB device that presents itself to the operating system, and its sole purpose is providing pass-through power to a USB A-type receptacle on itself. This would then be manageable by the operating system.

What I'm possibly trying to say here is a small, specialised, one port USB hub. Hmm... I'll have to see if I can borrow a USB hub from someone to test this theory. I've never had a need to own one.

Update: my adventures continue here.
