Hi eric gregori,

I am working in a certain development in which the MCF51jm128 needs to be connected to a HID (specifically a health care device). This development has been carried out under the DEMO JM of PEmicro, modifying the demos of CMX "USB_Lite_V1"

Due to the fact that I can not obtain a communication between these two devices, I am looking for a  technical support. 

I’m reading your application note. 

Are there many differences between USB_LITE_V1 and USB Stack ?

Can you send me a link, where can I free download it.

Thanks in advances

Hi Eric,

I have a Demo JM board with me which uses the MC9S08JM mcu.  I am currently using the accompanying hid-demo code provided and it uses the CMX USB stack. I am trying to enable more than 1 usb interface ( i.e. create a composite device) by modifying the hid-demo code, which I believe it should be quite a simple and minor tweak to the code but I have been unsuccessful so far. Maybe its not that simple as I have assumed. However to someone of your level of expertise, it would probably be a very simple and minor change. Can you please advise me on I can achieve this?

Thanks.

Regards,

John
