Tascam US-144mkII/US-122mkII

Preliminary Information
Release Year	~2009
Leak Risk	Medium
Batteries	None
Mounting Technology	Through Hole, SMD
Capacitor Types	Aluminum Electrolytic, Ceramic
Destructive Entry	No

A portable USB 2.0 audio interface released by TASCAM in around 2009, using bus power. Not compliant with the USB2 audio standard. Named similarly to the historical TASCAM 122 MkII and TASCAM 144 MkII, which are different devices.

Known Issues

No audio

Causes

• This device is not compliant with the USB2 audio standard and requires a unique driver to be fully functional.

Solutions

• If you are on a version of Windows or MacOS where you are able to install the proprietary driver, install the driver from TASCAM's website. If you are on desktop Linux, you are able to use the usbusx2y driver along with JACK. You will need to blacklist the USB audio driver, and drop in configuration for ALSA which allows JACK to understand how to use this interface. It will be listed as a US122L.

Disassembly Notes

The device has multiple tension fits which are easy to accidentally damage. The device has a small number of screws that are identical in basic dimensions, colouration, and head to another type of screw in the device, but have a completely different thread, so inspect the threads of screws when removing them.
