Hello all,

For reference, I am working with LPC4330Xplorer board, trying to access the M4 core. I am also working in Linux.

I have been successful in downloading the Virtual Serial example project, however, when I go to test the echo functionality I am given the following script:
[FONT=Courier New][SIZE=2]
[  183.818893] usb 2-4: >config 1 interface 0 altsetting 0 endpoint 0x81 has an invalid bInterval 255, changing to 11

mtp-probe: checking bus 2, device 2: "/sys/devices/pci0000:00/0000:00:13.2/usb2/2-4"

mtp-probe: bus: 2, device: 2 was not an MTP device[/SIZE][/FONT][SIZE=2]
I was wondering if anyone new a solution to the problem, as I have exhausted all ideas. I have configured all linked projects correctly, but I think there might be a problem with the descriptor file, but I am not sure what to do with it.
