Hello.
With an firmware not updated since «Last update May 9, 2011»
I think it's safe to say that this card will never work at higher
sample rate - running linux.
It's not «legacy» on the Sound Devices web site, i wonder why.
The list keep an old talk on this card and this problem :

Older :

And i can quote a support email from Sound Devices where i asked about
this issues - wich is not an issue for them for sure.

Hello You,
Thank you for contacting Sound Devices. I don't know when or if they
will make this request available but I will gladly pass this request to
engineering for future firmware consideration. Thanks.
Best Regards,
John Doe

Audio Class 1 is defined for up to 48kHz.
Audio Class 2 is can use higher sample rates.
It seems that the Sound Devices Pre2 defaults to class 1 mode, but
based on the documentation it seems to have a class 2 mode
available. At this point you would need to contact Sound Devices to
confirm it is actually class 2 compliant, or if it uses a
proprietary driver. If it is class 2 compliant, you need to know
how to make the device switch to class 2 mode.
It is the other way around: The USBPre2 defaults to usb2 mode, and is
class compliant there. In class compliant mode, it is limited to
24/48.
I recall that to get into usb1 mode, I needed to push one of the
buttons on the device during connection to the PC. I don't know
whether this is still the case in newer firmware releases.
