Seems to work fine with an ES-3, and with an ES-5.The USBStreamer B is a miniature multi-channel USB to ADAT or Toslink interface with native support of audio files with format up to 24bit/192kHz. Packaged in a box, this interface is the perfect USB interface for DAC or ADAT multichannel audio interface without USB input.
The USBStreamer utilizes high speed USB2.0 along with the Audio Class 2.0 implementation to simultaneously provide up to 8channels of playback along with 8channel of recording over the ADAT standard. The unit is USB self powered and installed in a matter of seconds with compatible ASIO drivers for both Mac/Windows platforms.
So this is a nice option for e.g. live performance when you just need to hook your modular up to a laptop. Cheap too - 115 USD.
