Hello, I am trying to calibrate my eChook telemetry board, but the computer isn't detecting the Arduino nano. The first time (when i was programming it), it worked fine. I programmed it at first on a windows with the CH340 drivers installed. Now when i tried the same, the windows computer said "USB not recognized (driver problem)". I also tried it on Ubuntu 20.04.5 LTS where the CH340 drivers are built-in. It's still not detecting the Arduino (its not showing up when i do 'lsusb' in terminal). When i run 'dmesg -w' and plug in the Arduino nano I get these messages:
usb 1-3: new full-speed USB device number 19 using xhci_hcd
usb 1-3: device descriptor read/64, error -71

Thank you,

Hi Juljus,
You've done a thorough check! Is the arduino otherwise working, lights flashing, sending data over bluetooth etc?
Did you test with the arduino plugged into the eChook board? If so, could you check again with it unplugged - That will check that something on the board isn't pulling the 5v rail down a little too much and upsetting the CH340 chip.
If that was tested with the arduino unplugged it sounds like something has killed the CH340g chip which isn't common but I have seen with another team - we never actually worked out exactly what was causing it, but we went over the eChook board and reflowed all the solder joints and afaik it's not killed an Arduino since.
Unfortunately, it's quite likely you need a new Arduino but it's worth trying to work out what happened to this one before plugging a new one in. If you're handy with soldering and have a reflow station it's possible to swap a new CH340g in.

The arduino is otherwise working, i can connect to it in the app and it sends data.
I tested it with the arduino unplugged.
Thanks a lot for the reply!

That definitely sounds like a dead CH340 chip I'm afraid. For USB programming that arduino is dead unless you can replace the chip. Alternatively if you're determined to use that arduino you can use a second arduino as a programmer/communication bridge for it. docs.arduino.cc/built-in-examples/arduino-isp/ArduinoISPIt's worth checking over your board and trying to find anything that might have caused it before plugging in a new arduino. |

I used an Arduino UNO for programming the nano, and it worked really well, thank you!
