I just received an ESP32-2432S028 in the mail and plugged it in to USB and fired up the Arduino IDE to try and mess with it. But no dice.. It turns out this particular dev board uses CH341 serial to USB converter, for which a standard driver is in fact included with the kernal. DMESG reports the device gets connected as ttyUSB0, but then the following happens:
[1089016.769711] usb 1-12: USB disconnect, device number 7
[1089026.049960] usb 1-12: new full-speed USB device number 8 using xhci_hcd
[1089026.341566] usb 1-12: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice=81.33
[1089026.341575] usb 1-12: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[1089026.341580] usb 1-12: Product: USB Serial
[1089026.350406] ch341 1-12:1.0: ch341-uart converter detected
[1089026.364430] usb 1-12: ch341-uart converter now attached to ttyUSB0
[1089026.965382] input: BRLTTY 6.4 Linux Screen Driver Keyboard as /devices/virtual/input/input105
[1089027.081355] usb 1-12: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1
[1089027.088620] ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
[1089027.088678] ch341 1-12:1.0: device disconnected
Sadly, or perhaps rather not for accesibility sake, the device gets identified as a screen based keyboard by the Braile TTY system, and disconnects the CH341 in favor of using the screen keyboard through BRLTTY.
If you are not a blind person, then it is unlikely you need BRLTTY, and in this case, the fix is to simply remove the BRLTTY system to get back to the ch341 getting used directly and not substituted out by BRLTTY. To do this, simply execute sudo apt remove brltty and then re-connect
To retrieve files from a GoPro 9 Black on linux, you need to change a default factory setting on the camera. The setting is under Connections -> USB, and you need to change the connection type from “gopro connect” to “MTP”. Once you do that, you can plug your gopro into a USB 3 or USB-c port and transfer files from a mounted file directory. Most modern distros recognize it as a cell-phone device. From there, the files can be found by double clicking the Hero9 item in the file chooser, and then by going to the DCIM folder.
