Hi, 
    I have prepared an SDK from Cube for CDC FS device with one endpoint for data IN  and one endpoint for data OUT. It works well as expected but with slightly less data rate than anticipated. I can increase HCLK to raise the data rate but it causes problems in other modules. So I though about increasing IN endpoint from 1 to 2 or 3 to achieve faster data rate and failed to get it work. I have successfully configured the device and PC can detect a VCP, but can not transmit data. So, before I spend anytime in further investigation I would like to know following things:
1) Is it possible to have more than one IN bulk data endpoints for CDC FS ?
2) If so, will there be an increase in the data rate while using two/more endpoints ?

Regards,
Jagadeep.
