Don't expect to see a /dev/ttyACM device with a digispark

I just thought I'd record this in case someone from linux land runs into the same problem I had. It seems that even though the udev rules files include with the digispark software package mention /dev/ttyACM? it seems that the device files are never created. What I found that all you have to do is to hit the upload button and plug in the board. I never did see a ttyACM file from a digispark. All's good now.

This is likely due to it only sticking around for 5 seconds or until the upload is complete - as that is the only time it is in bootloader mode - I could be wrong though, I won't claim to be a linux expert

What does udevadm monitor tell, wehn you run that as root, while plugging the digispark in?

I'm having this problem too - the udevadm monitor command shows plenty of activity connecting a normal arduino board to port ttyACM0 (and sketch uploading works just fine with the 1.0.5 and a normal arduino).

But, when I plug in the digispark absolutely nothing happens in the udevadm monitor - but the digispark does power up and runs a sketch that I uploaded from a windows laptop last week.  I'd go back to using that laptop, but the hard drive went into a chittering death spiral and it won't boot anymore, so a Linux Mint 17 (Ubuntu based) is all that's left in the house.

Thanks,
