Hi,

[FONT=Arial][SIZE=2]I have an application code for firmware development which is run on LPC1343, the source code contains the  codes of usbhidrom(one function for this) and autoisp which is calling the ISP bootloader(one function).
I simply call the the function of HIDrom and ReInvokeISP in the main function. During debugging only the ISPBootloader is enumerated or found in the device manager, while the HIDRom is not. If I comment out the function of ispbootloader and run the application, the HIDrom is working. So what's the reason why this thing happened? Could someone explain me about this? Why is it if the two function is running, only the ispbootloader is executed?what happen for the usb hid?

:confused::confused::confused::confused:

Thanks.[/SIZE][/FONT]

There is an example for CDC/MSC Composite device here:

Not sure if it is possible to do this with the USB BootROM code.

So it is possible to create a composite device for usbhid on-chip rom together with bootloader?
How, coud I do that?

I think that to enumerate as multiple devices, you need to be a USB Composite device.
