[SOLVED]Teensy 3.0: USB interface dead?
Hi to everybody.
Since I cut the USB power from the battery power (as explained in this post) I have a really big issue with my Teensy 3.0.
It simply doesn t work.
Putting both power I can see the led blinking (because it was so in the last program I could upload), but I m no more able to communicate to the board.
Im using Linux (debian) and when I insert the USB cable into the PC I can see the board:
but in the serial folder I cannot find it anyway:
so I cannot connect to the /dev/ttyACM0 as requested by Teensyrduino.
Of course rebboting didnt help.
What could I do? What could I check?
Thanks
