Cubietruck USB is not working

Question

I am using a Cubietruck with a Revision A A20 Dual Core chip with the OS given here, version 1.00. There is also a 1.01 version, which I tried to flash onto it. It succeeded, but then I realized it was for the Revision B chip. I immediately re-flashed it with the 1.01 version. But now there is one problem - the USB on the Cubietruck does not work anymore. Any device I attach to it does not show any signs of even being powered on. For example, I have a mouse which lights up a LED when it receives power. When I plug it in, it does not work. It is the same for any device. I tried checking the solder joints on the USB connector but they were all fine. Any help/suggestions/have you got this bug?

Answer 1

How do you power your Cubietruck ? If you are using the USB OTG port, then the USB host ports are not powered.
