Hmm... 192kHz * 24bit * stereo =~ 10Mb/s

So, USB1 (12Mb/s max) might indeed be a bit tight for
super-top-quality digital, but USB2 (released 20 years ago) has a max
bandwidth of 480Mb/s which should provide more than ample bandwidth
(even if in practice you're unlikely to be able to make use of much more
than half of that bandwidth).
