Good evening. I am using ubuntu 22.04 lts 64bit. I want to program an esp8266 board with arduino ide. The card is equipped with the CP2102 cip but the system does not load the cp210X.ko driver, nor usbserial.ko and therefore I do not see the comXX port. The driver is present in the kernel folder cell associated with my version 5.19.0-41. With ubuntu version 18.04 lts and kernel 4.x it worked.

Watch `sudo journalctl --follow` as you connect the device. Does `id` show you're in the additional group (probably `tty`) as the `/dev` entry?

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.
