    Hi Folks,

    OS: Debian 64 bit
    Linux kernel 3.2
    Teensy 3.1

    Got started with my Teensy 3.1 last night and everything went as expected, using just the loader for blink fast/slow and then Teensyduino to get it sending midi messages via USB which I could hapilly see arriving on the laptop.

    Powered off the laptop over night (teensy still connected via USB) & when I next tried to do anything with the loader, nothing happened when I pressed the button (having uploaded a new sketch).

    When I first plugged it in (before having done anything) I noticed it appear in syslog, and listed as USB device (via lsusb). It no longer presents itself in syslog or lsusb when I plug it in.

    I felt sure it must be toasted, but in fiddling about, I notice that if I connect 3.3v to the reset 'pin' on the under side of the board, I get the follwoing in syslog (that I'd expect from just plugging it in to USB):

    and also...

    Bus 001 Device 019: ID 16c0:0485 VOTI Teensyduino MIDI

    When I then release the 3.3v from the reset pin I get the following in syslog as though I'd disconnected the USB device:

    Jun 26 16:36:56 grizzly kernel: [ 1052.657775] usb 1-1: USB disconnect, device number 21

    Any help I can get would be greatly appreciated.

    Thanks in advance,

    Hey There!!!!

    I've been working with teensy for a while but i decided to upgrade my Windows 10 laptop changing the disk to SSD.

    After installing Arduino and Teensyduino i can't upload the sketch ssutomatically from Arduino...

    The teensy shows on PORT.

    Arduino opens teensy loader but the i does nothing and i need to press reset button.

    Anyone can help????
