a 100% guaranteed firewire interface for linux?

Hi folks,

I need to buy a mobile áudio interface to give some linux áudio workshops here in Brazil.
I saw some options listed "suported" in the ffado database, but also lots of forums with people saying they can't use that devices in their machines.

So, I'm very afraid of buying something that won't work, and this interfaces here in Brazil are very very expensive... : (

Could you suggest me some interfaces that are guaranteed to work for me?
I was especially thinking about the edirol fa-66.

my laptop is a hp pavillion dv6700 with ubuntu 8.04

thanks a lot you all!

surian

Most problems with laptops are because of:
a) Firewire-controller sharing the interrupt with something else. Normally
this shouldn't be a problem but with laptops you can (almost) never change
the interrupts of the devices and are stuck with fw, graphics and usb sharing
one interrupt if you have bad luck. If things are good its 'just' fw and wifi
sharing...
b) Bad fw controllers. Some ricoh chips are bad, some aren't. Somewhere on
ffado.org there is or should be a list of good and bad controllers.

BTW: I have a presonus firepod and that works great both with ffado and
freebob. If you just need it to work, use freebob.
And either take your laptop (with a working(?) install of freebob or ffado) to
the dealer or if you are in germany or a country with similar laws, order
online. Then its two weeks return without any fee, reasons or whatsoever. And
at least thomann.de handles that (the 3-years warranty comes as a bonus).

Hi folks,

Just to end this thread..
I bought an Edirol Fa-66 and, after installing a fresh ubuntu studio, it was almost plug and play!
uhuuuuuuuuuuuuuuuuuuuuuuuuuuu!!!

Jack is stable using freebob with 4ms latency --- sample rate is 48kHz /// 64 frames/period /// 3 periods buffer

My laptop is an HP Pavillion 6700 running ubuntu studio 8.04 with kernel 2.6.24-19-rt
the firewire chipset is: Ricoh Co Ltd R5C832 IEEE 1394 Controller

The only thing I had to do was:
# modprobe raw1394
and then change it's permission on /dev/raw1394

thanks for the answers!
