Hi all, I tried figuring some stuff out and on device manager in windows 11, it just says Otherdevices>SerialPort with a question mark. Now I tried downloading a driver to it by updating and it is giving error "Windows could not find drivers for your device". How do I work this out please help!
What are the VID and PID. Or what is the TTL-to-USB chip on the board; this is the chip closest to the USB port.
For the VID/PID, right click the SerialPort in device manager, select properties, tab details and select Hardware Ids. Below an example (this is for a Nano clone with CH340 TTL-to-USB converter)
Is this your first experience with Arduino? Or did this use to work on e.g. Windows 10 and you upgraded?
I had windows 10 and when I worked on Arduino it worked fine I believe and then updated to windows 11 and got busy then I started working on Arduino again and it gave this error as i stated. I am new to arduino for aa uni project.
VID/PID:
BTHENUM{00000000-0000-0000-0099-aabbccddeeff}_VID&00010094_PID&0123
BTHENUM{00000000-0000-0000-0099-aabbccddeeff}_LOCALMFG&005d
is this what you were asking for? Hope this helps.
That was indeed what I asked for. The VID (00010094) looks very odd; it's usually a 4digit hex value.
- That is either the way Windows11 works. If you have access to another (non-Windows11) PC (e.g. a friend), you can check it there.
or
- There something is wrong with the 16U2. You can try to burn the firmware using Atmel Flip and see if that solves the problem. If that does not solve the problem, I do not know a solution (except for possibly rolling back to Windows 10).
Maybe others can advise.
Note:
I'm still on Win10 so can't verify.
I will try option 2. I tired using windows 10 and a different cable so the results were same, is it possible that the board is damaged?
Yes.
I troubleshooted it. Apparently the 16U2 chip is damaged. Other boards work fine. Have to order a new one.
Thanks!
