I am trying to connect the arduino uno to the arduino Idle, but I've got troubles and I don't have any ideas how to fix it.

Thats the message from dmesg.

Starting with OS & release details is usually a good start. You've tagged *drivers* which are kernel modules; but we've not details as to what software stack you're actually using (LTS releases offer two stacks too)

I had this as well, finally tracked it down to the kernel update from 5.4.0-73-generic to 5.4.0-74-generic on or around 10th June.

I used Grub to boot into 5.4.0-73 and all worked fine

This was on 20.04.2 LTS

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
