I am using an Arduino UNO which worked fine until today. My system: Ubuntu 18.04
Now, the IDE can no longer connect to it:
- Cannot do any sketch upload
- Cannot ask for board info
- No USB ports shown in tools --> port (only 2 serial ports shown)
ttyyACM0not showing up in
dmesg show that the board is recognized somehow.
Bus 001 Device 012: ID 03eb:2fef Atmel Corp.
[ 2922.171042] usb 1-1.3: new full-speed USB device number 12 using ehci-pci [ 2922.282047] usb 1-1.3: New USB device found, idVendor=03eb, idProduct=2fef [ 2922.282052] usb 1-1.3: New USB device strings: Mfr=0, Product=1, SerialNumber=0
The problem is the same on 2 different computers, which leads me to suspect that there is something wrong with the board. Is it possible that a board be shown by both
lsusb and still be malfunctioning ?
