Did you hold down input 1 source select when you started the device? The
quick start guide indicates that will force the device into full speed
mode (i.e. 12Mb/s USB 1 speed rather than 480Mb/s USB 2 high speed).
The Sound Devices information seems out of date, the documentation
indicates that linux will only support full speed mode, but I think that
is not correct. If you held down input 1 select when powering on to force
full speed mode, do not do that, let the device initialize in high speed
mode. Linux USB driver has supported USB 2 audio class and high speed
mode for quite a long time.
The output I posted is in USB 2 mode.
I realized this too after reading the manual. And looked at the
different output of lsusb -t (the difference is only the indication as
you say 12MB/s vs 480MB/s)
I should inform them to update the manual.
I realized there is also a alsa mailing list. I guess to evaluate if
there are possibilities to improve the driver I should go there.
thanks for all the comments.
