just got an arduino beginners kit, followed the instructions to get the blink program working but i keep getting “can’t open device “/dev/ttyACM0”: Input/output error”
i added myself to the dialout group and logged out and in. still nothing. tried the online IDE but get the same error message.
googled the issue but its all about what ive already done
any ideas?
ubuntu 20.10
Which kit are you using? Some variants of the Uno use a different USB-Serial converter, though most of them have driver support built into the linux kernel so it shouldn’t be an issue.
Here’s something I found with a quick google which might help:
This stack-exchange post gives the same solution, so fingers crossed!
yes there is only one port to select, it works on my other ubuntu machine and windows, just not this one. i think it might be a problem with the kernel
“Turn it off and on again” works very often. It can be a bit of a nuclear option when it comes to an OS, but it does get the job done more often than not! Worst case you should be able to eliminate OS level stuff and narrow it down to likely a hardware compatibility issue on that machine.
ok all good, re-installed ubuntu over the pop-os. my guess is some update i forced in the past messed up the kernel and only surfaced its head now. the risk with doing things this way is loosing all you data.
