512 and 3 periods at 48K is not such a setup as the OP wants and we
were not arguing about non-RT kernels, we were arguing about non-rt
priority, you could use a generic Ubuntu kernel with 'threadirqs' to
get rt priority for USB devices. The lowlatency kernel is a non-rt
kernel, too, just with minor configuration changes, for the official
lowlatency kernel e.g. 'threadirqs' needs not to be added to the boot
line options.

I'm not aware that a lot of people got this to work at all.
Don't know about a link to anything, but lsusb on my laptop just know

Where is the link to at least one of those many
people using the
PCM2902C with 64 frames at 48K?
It's currently running with buffer size 512 and 3 periods at 48K,
10.7msec latency. On a non-RT kernel.
