My Ultralite AVB is OK on a USB3 port (it's just USB2  -but works fine on a USB3 port) - so I would guess that the newer ones are fine.
You could check with MOTU...

The converters are newer than mkIII units... and have slightly lower noise-floor.

the convertors are newer on the avb series? or on mark 4 as well?

Yes, the larger AVB series have slightly better specs than the Fireface UFX.
 
The Ultralite AVB has the same converters as the mkIII series, but re-engineered to provide lower noise-floor.

• The MOTU 896HD and mkIII series had an average noise-floor of ~-107dB
• The Ultralite AVB has an average noise-floor of ~-110dB

Though I haven't measured the Ultralite mk4, it's using technology from the Ultralite AVB.
I'd assume they're using the same converters/design as the Ultralite AVB.
 

thanks Jim

after debating over the Mk4 vs a Presonus 192M with a price reduction, I just ordered the Mk4.  I've had a Focusrite Pro24 FW for many years, and I hope the MOTU will last for many more.  Figured if I upgrade my mobo in the next year (it's 4 yrs old... is that too old?), I can use the USB since firewire seems to be an outdated concept.

After 2 days using the mk4, I'm loving it. Music seems cleaner with more fidelity... hard to explain but kind of like listening to a low quality mp3@128kb vs the wave file. I heard things on songs I've never noticed before. I was thinking about upgrading monitors but I'm good for now.
The matrix will take some getting used to, but I like the dsp where I can run inputs thru the motu mixer. It works fine w the latest Win 10 for me, and no probs w SPLAT. Knock on wood, hope this works for years like my other equip.

Thanks for this feedback.I'm in a dilemma whether to go for motu or RME and I'm looking for good reviews on motu from the sonar community.

Yep:)

I have an 828/3 and ultralite /3 and often use them standalone, so I am concerned that in the process of adding a +1 to the version number to the mk4, the ultralite lost 5 knobs along the way.. i suspect this means that using the knobs for standalone mixer duties is pretty much lost?..

actually I m checking to get the moto ultralite mk4 or the Studio 192 mobile
 
 how it is the 192? do you have problem with latency cause i read that have some problem with latency so you have to  choose high sample buffer  when you use virtual instruments.
 
how is the motu mk4 latency?
 
i compose music with a lot of virtual instruments so i dont wanna have have problem with RTL
