tried to change libusb headers in micronucleus_lib.h as I found at micronucleus/micronucleus#81 (comment)

Why did you do that, couldn't you translate the original source? This issue #81 is very old, and the problem was that the translation did not work.

Micronucleus combined with USB3 can be problematic - you could try with an USB2 hub in between.

[g1ra]

@Ho-Ro USB2 don't work either . @Ho-Ro I looked in compile a bootloader with different libusb . But I couldn't find anything there for setting USB . so I tried compiling commandline micronucleus . Seems that other versions of commandline micronucleus does not make a difference . I tried with other versions too from other repos too .

only a bootloader matters . With micronucleus-1.11.hex I can connect immediately no problems , but all the newer bootloaders are not connecting . I'm thinking there must be something related to how bootloader connect to my linux libusb .

I did compile t85_entry_on_powerOn_activePullup_fastExit on Linux , and flash it . Not working either . What can I try changing in configurations for USB?

@Ho-Ro did you tried using linux with t85_entry_on_powerOn_activePullup_fastExit ?

[Ho-Ro]

did you tried using linux with t85_entry_on_powerOn_activePullup_fastExit ?

I did - but I never used micronucleus or bootloader since years :(

[g1ra]

suspect the issue must be caused by some changes in micronucleus-firmware/firmware/usbdrv/ which makes Linux libusb incompatible
