Data transfer using Digispark ATtiny85

Hello there

I'm trying to send some data from Digispark USB attiny85 to pc and from pc to attiny. The problem resides with digispark usb doesnt allow serial monitor. What it does allow is use the DigiKeyboard library to write to a on the keyboard to whereever the cursor is located, and that's not so pratical.
I didn't wanted to work with files, just preferly wanted to send the data directly and a program on the pc would read and send back the answer.

Any advice for a newbie is welcome
Best Regards

You forgot the link to that special hardware you're using.

I'm not sure I really understand your problem but if I guess right, you need the CDC library from digistump:
