Hello,
In Host and Gadget systems, enabled the USB CDC drivers. Then nodes are created as /dev/ttyAcm0 and /dev/ttyGs0. Then opened the nodes and write and read back the data. It is working.
I want to test the performance of this interface and drivers. Do we have any utility for this? How to do the performance test?
What exactly do you want to measure? Determine that first before trying to find a test for that. Without knowing what you want to measure, it's hard to tell you how to measure it :)
good luck!

Thank you. I want to send the data at the rate of 5mbps from Host device to target device using USB CDC - ACM. In termios functions, how to configure this 5mbps as baud rate and USB payload size, i.e. packet size to be in 2K bytes. How to achieve this? -Thanks.
