I've a Cakewalk UA-101 interface, originally an Edirol product until Roland bought Edirol and decided to rebadge the interfaces as "Cakewalk".
It worked very well for several years until eventually the USB socket gave up. Stable round trip latency of around 12ms was pretty stable, though the UFX on the same PC hardware is better and handles far more ins and outs at while it's doing it.
The Roland supplied drivers were also pretty good. The only problem I recall was with Sonar X1 where adjusting the channel eqs while playing back a project resulted in a zipping noise and loop recording where each pass through the loop was shortened by the time set in the audio buffer. Switching to Roland's WASAPI drivers fixed that and the performance was very, very nearly as good as ASIO. Cake then fixed both problems as part of the series of X1 bug-fixes.
The Roland badged interfaces that replaced the ones they took over from Edirol never seem to have quite reached the same standard going by what I've read in various forums. A pity as a big Roland interface would have cost me quite a lot less than an RME.
