This part gives me some hope: it seems like you may be having an issue with your Digispark connection to the computer.
Recently, I was going through some old posts, looking for an answer to another issue. It seems that some times the USB does not connect very well. From your description, this may be the issue here.
Digistump suggests trying using a hub (I tried a cheapie hub given at a trade show, which worked for my issue.) I also remember back in the beginning of USB, some people had troubles with just using the PCB traces as fingers in the USB connection (like the Digispark has.) They did not make good connections to the USB socket. First, try using a hub, if that does not work, try using a pencil eraser to buff the exposed PCB traces on the Digispark USB connector to clean off the oxidation. Finally, if that also does not work, try to add a thick layer of solder (1/4 mm or so) to the traces, to thicken the connection a bit. Be careful to not use too much heat, or you may lift the traces off the board. Also, you need to scrub the rosin off with a stiff bristle brush (like a tooth brush) and plenty of alcohol.
Try that, and let us know what happens.

2020 and here.
Its been a long time, and we must start to work on Windows 10. (but i still have 7 for my fun).

Just to let you know that im using Arduino Teensy USB (Another Option to Digispark) and if the books doesnt lie here it says that the problem to Digispark could be the default driver-itself (or
 his version).
Im not an expert BUT...
The legend tells that Microsoft have an autorun driver detection and here is where all the magic starts.
have you seen that when you plug a keyboard or a mouse this devices are detected automatically? YES, thats what im saying.
So... passing the pencil rubber on the connector will not fix the problem. This require a new driver installation.

Then...
First, there must be a way to erase the default driver for Digispark. (We should search for just at least one device when this is recognized and start working).

What about the new driver?
I would really appreciate if Digispark works on this and share a solution, open source, or something new. In the meanwhile i will try to do it by my self to see what i can do.

It will take some time but i will let you know if i have success.

Don't forget to try the hub, that has had the greatest success rate for me.

Also, I do not have any Windows 10 systems, and so I will not be able to test anything regarding the drivers. If you want something tested with Linux Mint (19.2,) and a Tiny85-based Digispark clone, let me know.
