I have successfully tested the E-MU 0404 USB 2.0 Audio/MIDI Interface:


It's frequency response is flat up to 90 kHz. Unfortunately, it is not BUS-powered, which means that it requires an external power adapter.


The frequency response and anti-aliasing characteristics of such audio interfaces are primarily determined by the A/D converter chips in them. The above unit employs the AK5385A chip, whose pass-band filter characteristics (at fs=192 kHz) can be found at page 10 of the data sheet:
