Hi,
Some old posts exist about the UAC2 support for the Sound Devices USBPre2 but some
problem remains.
The current status is that this sound card is supported as a USB 1.1 card in high-speed
mode.
But this card is not seen as a Usb Audio Class 2 on Linux. On Mac OS X this card is
recognized as UAC2.
I have access to a PreSonus Audiobox 1818VSL today, and it gets
instantly recognised with 18+18 channels. I tested the analog inputs and
outputs, and these work fine with up to 24/96.
With lsusb, two configurations are shown, and both have
bInterfaceProtocol = 32.
Output of dmesg and lsusb here:
