First of all, let me say that I know absolutely nothing about usb development or even software or hardware development at all. It was (and is) just never anything I dealt with.

However I had this idea of a device that would be fun to have. I think it wouldn't be that hard to make, but since I know absolutely nothing I can't be sure about that. That's why I'm asking. Anyway, I had this idea for an usb-clock. Not just usb-powered, but a device that shows the system time. I googled for usb-clocks, but all I could find were usb-powered clocks that still need to be set manually. But the computer that they're attached to has a clock too, so why set it manually? I think the usb-device can simply read the system time of the computer it's attached to and display that. That's all it needs to do.

Am I right in this? Is this indeed possible? If so, where can I find such a device or who would be willing to make it?

Yes this is quite do-able. Actually would be a pretty good first project for someone.

Start with a red board, https://www.sparkfun.com/products/11575

Add an LCD, https://www.sparkfun.com/products/11851

And write some software.

The question then is, do you need it to be on when the PC is off, that means batteries, and then keeping time while the PC is down.
