Hey there,

I'm using a Lpc4330 (Cortex-M4 core), see info above.
We want to use the Lpc4330 as a Usb cdc host.
Could you provide some example code for that?
(The Lpcopen package contains usb cdc device and some other usb host examples, but no cdc host.)

Cheers,
    Joe Merten

Take a look at:

Thanks for your reply. After receiving the NXP's statement, that the lpcopen usb code (neither lpcusblib nor usbd) was made as ready to use / productivity purpose, I'd switched to Segger emUSB (they have ported their Usb host to Lpc4330 recently and testet a.o. with lpcxpresso 7.7.2 on the NGX Xplorer board).
