USB descriptor to usb hid and USB mass memory

[Prof.Wagner]

Hi Everyone,

I need to develop a device that sometimes runs like USB HID and sometimes USB mass memory. I dont know how to put 2 descriptor in the my device.

I will use PIC32 and language I can use mikrobasic or mikroc.

Somebody can help me how I can change the descriptor in run time inside of program?

When I turn on the device I need that it works like USB mass memory device after few seconds it need to run like usb hid.

I can not imagine like to do this changing of descriptor.

Thanks in advanced

Hello,

Take a look at our USB Device Library, it supports HID and mass storage:

Have you tried to write something already?

Kind regards,

Hi,

I developed several devices in USB HID and others in USB CDC using mikroBasic and MIkroC with PIC32 Host and device. What I don´t know is when I need to have the both USB HID and USB CDC together. I know that I need to have 2 descriptors, but I don´t know how I change one and another when my device needs to be USB HID or when my device need to be USB CDC.

Could you help me?

Regards
