Is anyone aware of a USB Switch that is programmable or controlled via the PC?

I am writing a test application that requires the device (a mobile phone) to be plugged in via USB to a PC for initialization and then plugged in to a wall charger for a particular test.

Ideally I'd be able to have the phone plugged into the switch and then have two outputs from the switch - one to the PC and one to the wall charger. And then be able to set which connection to use from the PC.

Any thoughts?

    I hate to say it, but this would be a trivial device for you to create yourself if you were willing to hack up a few USB cables. All you need is a four-pole double throw switch. Hook up all of your inputs and outputs, and bam, insta-USB switch. And it won't cost more then a dollar if you already have the cables! – Breakthrough Jun 23 '11 at 16:38
  • Ah, I see what you mean now - you want to use the switch *from* the PC. In that case, you could use a microcontroller (control it via USB or serial) to switch between the two with a bunch of relays. – Breakthrough Jun 23 '11 at 16:48
  • Right... That's similar to what I'm currently doing (switching using a PXI switch module)... But I was hoping to find a COTS solution. – J J Jun 24 '11 at 01:21
  • Get an Arduino and some relays :) – billc.cn Aug 01 '11 at 00:37

simple and cheap, will have to change it to operate relays instead of just powering lights.

I haven't build the powerswitch example, but have used vusb for both serial and keyboard projects. works with really cheap hardware.
