The ALSA USB Audio driver is already highly optimised. If you are seeing
specific issues the alsa-devel mailing list is a better place to discuss.

Or are you looking to optimise the kernel and operating system?

FYI, other LADers have been using usb devices with 64 frames per period
which provides less than 2ms round trip latency.
