Why isn't DigiSpark automatically recognized on other computers? I bought a DigiSpark (it is a development board based on the ATtiny85 microcontroller) yesterday and I wrote my first script.

I have no problems to run it on my personal PC (which I am using to program my DigiSpark). The problem is when I try to plug my DigiSpark to another PC, which doesn't have DigiSpark drivers installed. I tried to run it on two different PCs (Windows 7) and Windows just can not find DigiSpark drivers so my script does not run.

Of course I tried to plug in to different USB ports - unfortunately it did not help.

Any ideas what can I do to make my DigiSpark run on other PC without installing drivers by myself?

Thank you.
You will need to install the drivers before you can use it on other computers.
The drivers tell a Windows PC how to talk to the device.  The device is not a generic device so Windows can't use a fall back driver, like it could with a keyboard or monitor.
