In the past some manufacturers developed their own drivers.
Of course they had to comply with USB standards anyway, otherwise it wouldn't work but they were using bulk mode instead of isochronous mode (UAC1/2).
M2Tech was one. If I remember correctly they got a lot of complains about their drivers with the HiFace 1 and later switched to UAC1/2.
Centrance and TheSycon developed drivers for Win.
Today it is most of the time TheSycon / XMOS powering USBDAcs on Win.
OSX and Linux are UAC2 compatible from mid 2010.
I don't know if they are certified as well. In case of Linux I expect not simply because Linux is not a big company.
Most of the time the moment a new driver is released, there is a plethora of bug reports. Overtime this dies downs as the product matures.
I expect the same to happen in a couple of month when MS releases their implementation of UAC2.
In your case Google is your friend.
Do Google the brand/model of the products you are using and check for USB issues.

Thanks for the info. The UAC2 acronym has improved the quality of my search to understand the history, compatibility etc!
I had searched re my DAC, but there doesn't seem to be much info available from users. The manufacturer's website states compatibility, but I'm not so sure at this point - I have no idea what their USB implementation entails and they tweak their firmware very frequently for their other DACs.
That said, i am thinking more generally: under what obligation is a DAC manufacturer to prove compatibility as claimed?
Cheers,

No problems with USB 2.0 compliance since Windows 7 (actually before that). Your mileage may vary.
