This model has been discontinued. It has been replaced with the US-2x2.



After installing Windows 8.1 Update(KB 2919355), PC is re-booted up when system sound on Windows is played.

In case that 24 bit is being selected at the setting of "Select the sample rate and bit depth to be used when running in shared mode" on Windows, PC is re-booted up when system sound on Windows is played.

How do I authorize Cubase LE?

Cubase LE is authorized on the Steinberg website. Go to this page to get started. 

There is no MIDI input or output from my US-series interface when using it with Pro Tools 9 for Windows. 

Pro Tools 9 for Windows must be run from the administrator's account for MIDI to function. Launch Pro Tools in 'run this program as an administrator' mode. 

Pro Tools 9 for Windows will not launch with the US-series interface connected.

The latency setting must be the same in Pro Tools and in the US-series control panel. Change this in Pro Tools' Hardware Setup window, and in the US-series control panel.

How do I register my copy of Cubase LE? 

Please be aware that this activation system is designed and controlled by Steinberg and not TASCAM.

  1. Install Cubase LE 4 or Cubase LE 5

My US-144mkII is making a metalic sound with OSX 10.11 El Capitan. 

These noises are due to a bug in OSX on Macs with USB3. Apple is aware of it and we're hoping for a fix in an update to OSX 10.11 El Capitan.
