USB CDC Dual VCOM and MSC on Kinetis K40DN512

[tbryant]

Hello,

I'm working to produce a dual VCOM and MSC with FatFS application on the K40DN512 board.

I have gotten Dual VCOM on the Device stack & FatFS to work using SD Disk, but attempting to implement MSC has been challenging. I have seen people using the Device Configuration tool to configure some of the USB components but my processor does not support this.

Is there an easier way to configure the USB Device Descriptors through some form of a wizard to configure the proper endpoints and other descriptor info?

If not, has anyone successfully made a Dual CDC VCOM & MSC w/ FatFS system via the USB Device stack to work before? If so, what configurations did you use?

Any tips or guidance is appreciated.

Hello @tbryant 

I recommend you choosing the SDK demo that is closest to your requirements, for example usb_device_composite_cdc_msc_disk. First, confirm that it works well on your board, then add the second CDC interface, referring to:
