Removing that sleep probably makes some lower priority thread do not execute because the loop becomes continuous when the USB is not active. Do you have loweer priority threads?

No, I only have the one serial thread and the main (idle) thread does nothing...

Re: 16k USB devices and Chibios.
Could you try declaring USBDriver.state as volatile? I suspect the compiler optimizes it out if there is a function call in the loop (not just that sleep, any function). It is in usb_lld.h.
Alternatively try compiling with -O0.
