I have been using the older version of this audio interface with the recessed inputs and outputs for several years, and really have had little to no problems with it.
It supports ASIO, and the drivers are readily available on Numarks website to do so (Available in both Win7 and Win8+ flavors). The device will also output audio through WDM to Output 1 in a pinch (and simultaneously, if need be).
Only real gripe I have with the card is that the mic input only works passively (no input device) to the WDM output, hence the volume slider (If you connect to it through ASIO, the mic audio doesn't connect to any input or output). This would be a perfect 5 stars if the Line Input actually captured the microphone input (It reports the line input without any channels, so it's of no use).
