Re: libusb issue when opening device

Hi, I have posted some notes from my tests on two different systems at https://kyla.kiruna.se/nextcloud/index.php/s/SBc8jH4nS3FnoAZ A short summary: libusb is the same version, kernel and hardware are different. Only the Arch Linux system with kernel 5.4.15 on AMD hardware detects altsettings. I have also listed lsmod output in case conflicting modules would be loaded.

As you can see in the notes this works on the laptop, thanks! Best regards SM2YHP -- ------------------ Carl-Fredrik Enell Föraregatan 26B SE-98139 Kiruna +46705508256 -----------------
