Hoping I just missed something here, but I've got two MKR1000 that are not detected when plugged into USB and one gets warm really quickly after being plugged into USB.
I purchased several of the Arduino Engineering Kits for use in our labs and all the MKR1000, except these two, seem to work and are detected immediately when plugged in. Makes the classroom less interactive having these two boards not functioning right now, so the students are a bit bored, so any help would be greatly appreciated.
Specifics.....
Computer: Windows 10 (18363.592)
USB ports: 2 and 3
IDE - 1.8.11 - SAMD - 1.8.4
MKR1000 -
Plug boards in, and power LED comes on, no other LEDs
Swapped USB cables (used ones that came with the kit and one that did not)....nothing
Swapped USB port...nothing
Swapped computers....nothing
Double clicked the reset button....nothing
Held down the reset button...nothing
Plugged in a "good" MKR1000, it detects, verify connection and upload a simple sketch...unplug "good" MKR1000, plug in "suspect" MKR1000, change nothing else.....nothing (not detected)
Scanned the forums, tried a firmware update, but since it cannot detect, I cannot upload anything.....so here I am.
Help!
