Every time?

It looks like the USB DMX plugin, does it start if you disable that plugin in it's conf file before starting olad? Either way, disable all the other plugins and see if it changes things.

What USB devices do you have attached? Can you share lsusb -v.

An ola release or compiled from Git; master or 0.10 branch?

Try bumping up the libusb_debug_level:
https://docs.openlighting.org/ola/conf/ola-usbdmx.conf.html

Can you share your ola-usbdmx.conf file.

Try disabling enable_eurolite_mk2 if present.

[mikacousin]

Thank you for your quick reply !

Disabling USB DMX plugin allows to launch olad. Very good ! At least I can run olad now :-)

I tried master and 0.10 branch.

ola-usbdmx.conf file (eurolite_mk2 was already disabled):
enable_eurolite_mk2 = false
enabled = false
libusb_debug_level = 0

I tried to set libusb debug level to 4, but no more infos ...

No external USB devices attached.
lsusb -v :

Thank you for your quick reply !

Disabling USB DMX plugin allows to launch olad. Very good ! At least I can run olad now :-)

Ah that's good. Were you using that plugin?

I tried master and 0.10 branch.

ola-usbdmx.conf file (eurolite_mk2 was already disabled): enable_eurolite_mk2 = false enabled = false libusb_debug_level = 0

I tried to set libusb debug level to 4, but no more infos ...

I take it this line logged with a different number (i.e. it worked):
libs/usb/HotplugAgent.cpp:85: libusb_set_option(LIBUSB_OPTION_LOG_LEVEL, 0)

What version of libusb are you running? Is it pretty new given it's Arch? Can you easily try an older one?

[mikacousin]

Ah that's good. Were you using that plugin?

No, it was enabled by default. Now, I disabled all plugins I don't need :-)

What version of libusb are you running? Is it pretty new given it's Arch? Can you easily try an older one?

libusb 1.0.25, latest version. And no, I can't install an older one, sorry.

[mikacousin]

Finally, I was able to install libusb 1.0.24 and no more problem with USB DMX plugin enabled.

Segmentation fault only appears with 1.0.25

[peternewman]

Segmentation fault only appears with 1.0.25

Amazing thanks @mikacousin that's so useful!

You're also not alone (even on a different OS it happens):

[peternewman]

Would you minding commenting out this line on the broken version and see if it makes a difference (which will stop the whole hotplug agent):
https://github.com/OpenLightingProject/ola/blob/b6787ab/libs/usb/HotplugAgent.cpp#L93

Can you also try adding --use-async-libusb and --no-use-async-libusb to your olad command one at a time which should exercise the two different ways we do USB comms (and share the olad -l 4 for both). You could always disable all the other plugins first as I suspect it's only the USB one causing issues.

[peternewman]

I suspect this is probably the same issue we're seeing:
libusb/libusb#1059

[peternewman]

Can you give #1772 a go, I think that may fix it...
