Hi,
Having a ricoh firewire chipset here on a thinkpad t61. Not the best one
afaik.. Should I go for a usb (edirol for example) or firewire interface?

I had an JMicron (?) chipset on the on-board firewire plug on my laptop
which was also on the same IRQ as basically everything (ethernet,
graphics card, 2 usb ports etc.) I found no way to even get it to work
with the 2nd hand FA 101 I bought.
I then got a (cheap) firewire expresscard. The good thing was that the
express card slot has its own IRQ. The bad thing was that I discovered
the chipset was VIA (they don't tell on the packings) which seems to be
one of the worst around for audio and which would give me a "zombified"
sound card after a few minutes even with rt kernel and all the possible
tweaks explained in all the possible linux firewire/pro-audio tutorials
on the net.
Finally I got a firewire expresscard with Texas Instruments chipset
(again it took quite some research because it's not well advised on the
specs and in the stores), here in italy it's branded Digitus (but
careful because they also have a model with the VIA chipset). It now
seems to work well. No zombies... A few xruns though (but this was
playing heavy with Pd).
So it looks like the chipset is important... I have seen various
recommended firewire cards (and thus chipsets) on the sound card
manufacturers' pages so I think this is not a linux-related issue.

VIA should work, Focusrite even recommends using certain VIA chipsets.

Chipset is important, but a properly configured system is even more
important imho.

It means that that specific same configuration doesn't work with all
chipsets. Every system needs to be set up differently.

Ok so what is your suggestion to try and improve the situation? It would
be helpful to have some details.

Hello Lorenzo,
http://subversion.ffado.org/wiki/IrqPriorities
http://wiki.linuxmusicians.com/doku.php?id=system_configuration
The FFADO Wiki page about IRQ priorities is pretty much system specific.
The LinuxMusicians Wiki page contains more general tweaks and settings.

The T61 has cardslots right? Then a good option might be to get a
FireWire pcmcia card or ExpressCard and go for FireWire. And not all
Ricoh chipsets fail to work properly so a FireWire card might just work
with the onboard Ricoh controller.

This depends. There are Ricoh chipsets that work (even better with the quirks
of current kernels) and there are chipsets that don't work.
Should I go for a usb (edirol for example) or firewire
interface?
This also depends:
Do you want more then stereo-in-stereo-out? If yes, firewire is a sane
solution.
Do you want the ability to connect more then one devices, even if its only at
a later point? If yes, firewire is the only feasible solution. USB doesn't
really provide any synchronization or even synchronous data-transfer.
Which devices share the interrupts? If your firewire chip (built in or via
pccard) has its own interrupt while the usb ports share their interrupt with
each other and also with disk/wireless/screen, you will have better luck with
firewire.
(One advantage of usb is that it always has 5V which devices can use to run
and to create phantom power. Firewire in laptops is either 5-pin without +12V
or needs an extra power-adaptor to provide the +12V to power external devices
and provide phantom power.)
Have fun,
Arnold

That particular EHCI controller is implemented in a way that makes it
impossible to work around a bug in the Linux EHCI driver.
