I tried plugging in my friend's Traktor Kontrol X1 Mk2 and F1 into my
laptop running GNU/Linux (Fedora 21) and Mixxx compiled from git with
the --controllerDebug option. These are class-compliant HID devices,
although the lsusb output below shows that they also present a
nonstandard endpoint for firmware updates. Mixxx would not open them. I
have the udev rule from the wiki on my system and I tried both as my
normal user and as root. Is this an issue with my setup, Mixxx, hidapi,
or Linux? When I tried to enable the devices, I saw this error in the
Mixxx output:
Debug [Controller]: Opening HID device "Traktor Kontrol X1 MK2 2E0E_0"
by HID path 0001:000f:00
Debug [Controller]: Failed. Trying to open with make, model & serial no:
6092 4640 "CBC42E0E"
Warning [Controller]: Unable to open specific HID device "Traktor
Kontrol X1 MK2 2E0E_0" Trying now with just make and model. (This may
only open the first of multiple identical devices.)
Warning [Controller]: Unable to open HID device "Traktor Kontrol X1 MK2
2E0E_0"
(There was a similar error for the F1 but I forgot to save it.)
