Firewire ExpressCard permissions issues

I recently bought an ExpressCard Firewire adapter for my laptop:

http://www.amazon.co.uk/gp/product/B003 … ge_o00_s00

This was in order to connect an M-Audio Firewire Solo Audio interface, which I had been given.

According to this I need to run the following command to check if everything is basically set up correctly before attaching my device:

jackd -R -d firewire -v4

Doing so as root returns the required line:

02092612988: Fatal (ffado.cpp)[ 174] ffado_streaming_init: There are no devices on the bus

But doing so as a normal user returns the following error message:

1416923338463645: Fatal (devicemanager.cpp)[ 187] initialize: No firewire adapters (ports) found.
1416923338463651: Fatal (ffado.cpp)[ 160] ffado_streaming_init: Could not initialize device manager

Which suggests to me that this is simply a permissions problem.  Unfortunately, I have no idea how I would go about giving my user permissions to access this card - any suggestions?

Re: Firewire ExpressCard permissions issues

Nevermind, I created /etc/udev/rules.d/60-firewire-expresscard.rules with the following content:

KERNEL=="fw*", GROUP="audio", MODE="0664"

It appears to work after a reboot.
