I have a wroom32 (esp32) that I cannot detect via usb. I have tried this on two Ubuntu machines, both have the cp210x.ko module installed, but there is nothing showing up with lsusb, as you can see ....
The following shows the installation of the module for the 2102, the dmesg output of where the driver was properly installed.
I then plugged in the esp32 and there is nothing shown in lsusb or in the dmesg that it was inserted into the computer.
I have three (counting the spouses) machines and two batches of three boards from different vendors.... I have tried 5 of the 6 boards. Two are Ubuntu and one Windows 11. I've hit reset and boot...
Changed usb cables (multiple times)
I also looked for a braille entry in udev, but no such animal exists there...
jack@Kilo:~$ sudo modprobe cp210x
jack@Kilo:~$ dmesg | tail

I'd really would like to use these, but I can't seem to get them connected...
It is not detected in the spouses Windows 11 computer even after installing it's driver...
I've run this on two Ubuntu machines and my spouses Windows 11. All machines have the proper driver for the cp2102. I have 6 boards all 6 of them respond the same way. It was two groups of three boards from different vendors. I find it hard to believe they are all 'bad'...
The device is never seen by the OS ... dmesg shows no usb device inserted
I just loaded the server version of Ubuntu on one of the machines so I have the ability to run it 'live', I think.
Thanks... I thought I was going nuts.., I had changed out the usb cord with two others, same results.
I found 4 more and there was 1 in there that worked... So it took 6 cables to find the issue... or one that worked...
As a young field engineer it took me 4 sets of cables to get one that worked... I knew how they were made and how they tested the cables.... surprised me ...
Can't hardly believe something so similar happened again...
