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:

[ 183.818893] usb 2-4: >config 1 interface 0 altsetting 0 endpoint 0x81 has an invalid bInterval 255, changing to 11

[ 183.818906] usb 2-4: >config 1 interface 1 altsetting 0 bulk endpoint 0x3 has invalid maxpacket 16

[ 183.818914] usb 2-4: >config 1 interface 1 altsetting 0 bulk endpoint 0x82 has invalid maxpacket 16

[ 184.144427] usb 2-4: >New USB device found, idVendor=1fc9, idProduct=2047

[ 184.144438] usb 2-4: >New USB device strings: Mfr=1, Product=2, SerialNumber=0

[ 184.144445] usb 2-4: >Product: LPCUSBlib CDC Demo

[ 184.144451] usb 2-4: >Manufacturer: NXP

[ 184.157154] usb 2-4: >can't set config #1, error -32

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

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.

Thanks!

Hi,

Which Linux distri are you running? On our side, we have no problem running this example, from nxpUSBlib v0.98b, on Ubuntu 10.10 default USB driver.

With best regards,
