How can this happen? That routine is called from only two places.

are enabled. The ep_reset_338x() sets ep->desc = NULL to mark

This patch adds a minimum baud rate of 2400 for CP2105 SCI
According to the datasheet for CP2105, the SCI supports 2400 as the
lowest baud rate. As this is not heeded in the current code, an error
