Bug#452841: zaptel-source: occasionally fails to initialize with error -5 and never accepts calls

[Botond Botyanszki]

Hi,

I had the same problem with wcfxo reporting "probe of 0000:09:01.0 failed
with error -5"
Found the patch below at http://www.voip-info.org/wiki/view/X100P+clone , 
this solved the issue for me.

Regards,
Botond
