I've got a Sonore USB adapter that I've been using for my Uptone Regen and no longer require as I've decided to go with the Intona USB Isolator instead.
From Sonore website,
USB type-A plug to USB type-B plug
The Sonore USB Adapter is a USB type-A plug to USB type-B plug adapter replacement for the USB hard adapter supplied with some computer audio gear such as the Sonore microRendu and Uptone Audio Regen. These adapters are custom made by hand in the USA for Sonore by Cardas Audio.
These sell for $83 shipped new so if you've wanted to try one for less here's your chance.
$40 shipped.
