For corporate users, plugging a UCA200 into a USB-A port and running RCA to a conference phone system solves ground loop hums (thanks to the USB isolation). It is a cheap ground loop isolator with ADC/DAC.
Many DJs (Traktor/Serato) carry a UCA200 in their bag. It requires no drivers, is unbreakable (plastic absorbs drops), and if the main interface fails, the DJ can run master out from the mixer into the UCA200 to keep the stream alive. Driver Behringer U Control Uca200

For the price of a pizza, you get a USB sound card that solves niche problems better than $200 interfaces. It is the cockroach of the audio world: ugly, primitive, and nearly impossible to kill. As long as USB-A ports exist, the UCA200 will continue its quiet mission of digitizing the analog past. It requires no drivers, is unbreakable (plastic absorbs
