Re: Fwd: Adding timeouts to device access?

I think I got it!

I got interested in firewire-ohci quirks and my dmesg reported 0x0 for quirks by default.

And when reading thru:
<https://github.com/torvalds/linux/blob/1f988d0788f50d8464f957e793fab356e2937369/drivers/firewire/ohci.c#L330>

It seems that it should apply 0x4 and 0x10 so 0x14. I've created:
/etc/modprobe.d/firewire-ohci-quirks.conf
options firewire-ohci quirks=0x14

And now it seems to work fine each time. And also hot-plug started to work!

So the issue is that quirks that suppose to be applied are not for some reason.

Could someone verify this on their end?!
