usbmem example with LPC3131

Hi. I'm using LPC3131 demo board from embedded artists as a USB device (Full Speed or HS)

I have problem running the usbmem example

Kernel messages from linux (2.6.18) are:

"new high speed USB device using ehci_hcd and address 14
device descriptor read/64, error -110"

I have tried with modprobe -r ehci_hcd but with same result

Has anyone succeeded in running this example with same environment ?

Any other help would be appreciated. thks

  • Is that usbmem example working fine when it is connected to a Windows Desktop? If it works fine, then maybe you should update your Linux kernel?

    I don't know much about Linux; though there are many/several Linux experts in this forum, but this is a forum for KEIL/MCU.
