[pvrusb2] Lirc not creating /dev/lirc0!

[roger]

I keep getting this sporadic thing where Lirc refused to find my pvrusb
devices IR.

I am using kexec & tuxonice for hibernating.  And kexec (rebooting with)
seems to condone this issue.

The only method I've been able to use to hack around this issue.  Use
the pvrusb2 device with a windows box and start the pvrusb2 device from
a cold cold cold start to ensure windows loads the firmwares.


Here's a cat /proc/kmesg of pvrusb2, lirc_dev, lirc_i2c load sequence:
