Multiple USBD Devices

[michaeljfolz]

I want to use the nordic USB peripheral drivers to allow for the initialization of multiple devices. The end result of the project will be to have a single nordic creating 6 separate HID Classes (5 Joystick and 1 mass storage class). Each USB hid class should be separate in order to allow for the devices to operate at different frequencies regarding HID data. Does anyone have experience with this? I was hoping someone could point me in the right direction

Nordic SDK 15.2 - nrf52840 - PCA10056

Hi,

As a starting point, you should take a look at the usbd_hid_composite example, it shows you how to combine several HID classes as one composite device. See this link.

Thanks, i am having issues with using multiple types of devices. Right now i have 4 HID Generic Devices, i am attempting to add a cdc device but i am having issues. Using my code CDC on its own works fine but when i attempt to append even one hid device the system goes into an error state.

Please make sure that they use different endpoints and interface numbers.
