USB disappears

Hi Mark,

The bootloader runs for 8 seconds. So you should be able to get the USB working again for the user sketch by uploading any standard sketch (for example blink) within the 8 second period that the bootloader is running. To do get the upload process to work within the 8 second period it is sometimes usefull to keep the reset button of the board pressed in whilst the sketch is being compiled, and just releasing it when you see the Arduino IDE is starting to look for the serial port (turn on verbose mode in the Arduino IDE settings to see this extra information).

Please let me know how it goes.

Best Regards,

Loic

Thanks Loic, that got the USB back! Now to figure out why it is being corrupted...

Bootloader file specified but missing: /Applications/Arduino.app/Contents/Java/hardware/Industruino/avr/bootloaders/Bootloader.hex

Sketch uses 22,130 bytes (17%) of program storage space. Maximum is 126,976 bytes.
Global variables use 655 bytes of dynamic memory.
Board Industruino:avr:ind1286 doesn't define a 'build.board' preference. Auto-set to: AVR_IND1286
