https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235257 Bug ID: 235257 Summary: snd_uaudio not getting loaded automatically after migration to devmatch Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: usb@FreeBSD.org Reporter: maxsteciuk@gmail.com Certain USB modules such as snd_uaudio, uplcom are not loading automatically since /etc/devd/usb.conf was replaced by devmatch. When running devmatch tool with no arguments (as /etc/rc.d/devmatch script has) it does not return any matches. I checked /boot/kernel/linker.hints has the pnpinfo string for uaudio. Also /sys/dev/sound/usb/uaudio.c has call to USB_PNP_HOST_INFO(uaudio_dev) macro. >>>audio >>>snd_uaudio.ko >>>uhub >>>M:mask;I:vendor;I:product;L:release;G:release;I:devclass;I:devsubclass;I:devpr>>>oto;I:intclass;I:intsubclass;I:intprotocol;T:mode=host Yet devmatch was not able to match module by the parsed fields. When debugging I noticed the following mismatch condition for type 'I' was hit (values were different) /sbin/devmatch/devmatch.c:319-328 >>>ival = getint(&ptr); >>>... >>>v = pnpval_as_int(cp + 2, pnpinfo); >>>... >>> case 'I': >>> if(v != ival) notme++; BSDCan 2018 devmatch presentation mentioned some USB module issues due to pnpinfo string being too long for 128 byte limit. Is this one of the cases? Or is this because vendorID/productID of my device is not in the uaudio module table? Could you please help me understand how devmatch is supposed to work for such cases? Do I need to configure anything else? Please let me know if additional information is needed. The environment: OS: 13.0-CURRENT FreeBSD 13.0-CURRENT GENERIC-NODEBUG amd64 Build date/time: 2019/01/21 16:38:41 Thanks, Max -- You are receiving this mail because: You are the assignee for the bug.help
