USB doesn't have a built-in sample rate; audio samples are transported
USB does have a bit rate and a frame rate, but neither of these can be
changed. The only exception is the frame rate on UHCI controllers; to
change the frame length, change the initialization of the USBSOF
register in the configure_hc() function in uhci-hcd.c.
Why would you want to do this?
