I'm using the BF548 on my own board.

I want to use the BF as a USB peripheral device connected to a PC.

I need to transfer data (from a DDR connected to the BF) to the PC, with effective data rate of
6 MBytes/Sec - guarantee of delivery.

Q1: It seems that the data rate of the bulk_loopback_bf548 demo (hostapp.exe is running on the PC) is 300 KBytes/Sec.
What can I do to raise the data rate?

Q2: The hardware reference does not include programming examples regarding the USB controller. Can you link me to a place where it
available.
