It should be idential to that of the host side. If this happens after a while if means that the OTG FIFO size is incorrectly set, see this printout: > usbus0: Dynamic FIFO sizing detected, assuming 16Kbytes of FIFO RAM ^^^ try having a look in the driver where this comes from. Try setting 8Kbytes or 1KBytes. --HPS
