Which firewire controllers work well and which don't work?

Some of Ricoh chipsets are reported _not_ to work well, some seem to work fine.
NEC chipset has been tested by a developer and is reported to work fine,
but since Presonus advises against them, there must be a reason to avoid them.

So far, in order of preference (best to worst) according to developers:
Texas Instruments, VIA, NEC, O2 Micro (all are OHCI controllers)

NB: OHCI firewire cards are natively supported by Windows, no driver install necessary

According to Presonus :

> USB/firewire and s400/s800 combo cards are not compatible. Symptoms are usually no audio
> recording/playback but device will install and sync, erratic audio performance and rarely will not allow
> the device to install or sync. We recommend a firewire card that ONLY has s400 firewire connections and
> preferably with a Texas Instruments or VIA chipset.

> Firewire cards with NEC chipsets are not compatible. Symptoms are similar or the same as combo cards.
