The board isn't detected on linux

mscrstuff

Hello I was using my at tiny 88 on a windows computer and everything worked fine but on linux when I plug in the board to upload the code the board doesn't get detected.
Thanks

You need to provide the udev rules:

https://raw.githubusercontent.com/micronucleus/micronucleus/master/commandline/49-micronucleus.rules

Second, you may get a complaint that the micronucleus version (the one you get through additional board manager) is not compatible with your hardware board.

In that case, you need to build micronucleus binary for your platform and replace the binary micronucleus in the folder
~/.arduino15/packages/mhetlive/tools/micronucleus/2.0a4
(or similar)
with your newly compiled binary.

If you do both of this, then it should work fine, at least it works for me.

I have the same problem with the usb port on Linux. You, Pavel, mentioned the folder "~/.arduino15/packages/mhetlive/tools/micronucleus/2.0a4". But I have no "~/.arduino15/packages/mhetlive" in my system at all. But MH-ET LIVE Tiny88(16.0Mhz) is installed in the ArduinoIDE. Where may be the problem?

@Pavel

I have tried adding the udev rules, but even after restart, the board is not recognised. The output from dmesg is below.

Any suggestions?
TIA

Update:

I discovered that the board I have has different IDs. I've updated the rules to reflect that, but still no joy.

Added rules:

# Added 20230604 to match MH-ET Live ATTiny88
# Vendor  ID: 1A86
# Product ID: 7523
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", MODE:="0666", ENV{ID_MM_DEVICE_IGNO
