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?
