I don't think a stable sync via USB1.1 is possible, it's the nature of USB1.1 to have unpredictable dropouts and varying latency... how should the hardware know whether there's more latency or a change in tempo? IMHO that's the problem...
They have chosen USB1.1 in order to save money, now, it's a bottomless pit

I dont beleive it was specifically to save money. The audio industry is awash with companies who got into trouble at first attempt at writing USB audio drivers and failing miserably. I *beleive* that Access actually bought a known working driver and chip set from another company, and hence the choice of USB1.1. For USB2 they probably would have had to go it alone - which is very high risk and most companies fail miserably on first attempt not realising how hard it is to get a good driver for PC and MAc written first time around.
My personal opinion of the TI->VC audio channel is that its probably one of the most relaible USB audio implementations I have ever come across, allthough I think the latency is unreasonably high (maybe that was the other price of reliability).
From the above you can guess I have absolutely zero problems with the USB driver (as separate from VC). Not helpful tto you I know - I beleive you had a few BSDs? I cant speak for the ASIO implementation as I have never used it as I use a multi-channel firewire audio interface instead.
BTW - Its well worth having a good look around the kind of stuff you have running on your PC - I have had alot of problems in the past with audio caused by the most unlikely applications - especially sys tray apps.
If in doubt - dont let anything none essential apps that didnt ship with the OS (Mac or PC) auto-start. Most stuff that ships with the OS tends to be well behaved. Alot of other stuff isnt. I know especially of a number of people who have had serious audio problems with printer utilities in the sys tray on WinXP (why printer apps ffs??).
On sync - I mean sync either via hardwrae MIDI, or from the DAW application via VC. People with high quality audio cards and sync sources seem to fair better. Where the audio card comes in is that many applications use the audio clock as their reference souce for generating all application audio and midi timing (instead of using system clocks for midi timing). If you are getting the odd audio pop, then something is getting in the way of audio processing - that will also impact midi clock (depending on the App), and so I belive destabilise the TI.
Thats not saying their isnt a problem in the TI clock thats causing it to crash - I think their is - but with this chain of events, I can so easily see how the TI coulod get through internal testing and use by a bunch of beta testers prior to launch in high end studio and never or very rarely hit the issues users are seeing now.
