The manual says I must start the device holding the

"full speed" USB1.
Without this I can see the device, but I can't hear anything from it.

This is audio class 1.0.
Please show the "lsusb -v" output for 192 kHz mode.
From the website:
Class Compliant Drivers
As a class-compliant audio device, the USBPre 2 is limited to a
maximum data rate of 24-bit, 48 kHz in Windows, Linux, and Mac OS
versions 10.4 to 10.5.7.
Mac OS 10.5.8 and higher support the audio class 2.0 device and can
address the USBPre 2 up to 24-bit, 192 kHz.
Audio class 2.0 should work with Linux 2.6.35 (but an even newer
kernel wouldn't hurt). Which kernel version are you using?
