I have an Arduino UNO (clone, not original) that was working fine until a couple of days ago. Now, it does not show up when I connect it to my laptop.
Things that I've troubleshouted:
- USB cable is fine (tried with another Arduino).
USB ports are fine (tried with another Arduino).
Followed all the fixes and checks listed here and everything is successful.
I can upload sketches trough ICSP using a working Arduino.
I've tailed
syslogwhile connecting and disconnecting the failing Arduino and nothing shows up (it does when using the "good one").I've tried on a Windows 10 machine and it doesn't show up.
What else can I try?

1Unusual. Maybe it's not a real one or its a factory reject. Probably dead. Continue using ICSP or use a USB UART dongle with itMajenko– Majenko2020年01月27日 22:44:59 +00:00Commented Jan 27, 2020 at 22:44

@static_cast I see that your problem was solved by reuploading the bootloader. I've already try that and it didn't work :(Francisco Hanna– Francisco Hanna2020年01月30日 19:42:34 +00:00Commented Jan 30, 2020 at 19:42

I can't comment yet but have you updated your board manger for UNO on unbunto?
tools> Board> Board Manger> Search UNO
Kind of dumb to have to do that but it happen to me before and this was the solution I did.
