Request: USB bulk transfer

[skintigh]

I'd like to modify a button so the badge can connect to a USB peripheral that appears as a "mass storage device" and then do a number of sequences of reads and writes of 16 or 31 bytes. I know the vendor/device IDs.

Are there any examples you could share or pointers you could give me around MSC or bulk transfers?

I see you've commented out a lot of code dealing with udi_msc. I assume undoing that is the first step, then finding/following examples.
Thanks!

I never played with the host mode, only device mode. In Microchip Studio, the ASF Wizard will allow you to add the necessary modules for USB host mode. The udc_stop() command should turn off the USB device mode so that you can re-configure the USB hardware for host mode. Good luck!

Do you have any hints on how to write raw data to USB?

I've gone through their docs and tried dozens of functions. They have 440 functions for reading/writing bytes to USB, and not a single working example nor description of required setup that I can find.

Unfortunately I don't, sorry. I just used the USB serial example and slightly modified it for my needs.
