Content originally posted in LPCWare by muamw10 on Wed Feb 29 13:28:17 MST 2012 I'm working on a M2M project and need to interface to a wireless modem (verizon network) using CDC. I have the wireless modem dev board working as a USB CDC Serial device when I connect it into my PC and I can send it AT commands and get responses.
I have also setup the expresso board able to be seen as a CDC Serial device using the CDC example code.
But now, I need to make the LPC1769 the actual Host Controller to talk to the wireless modem. I've been hacking on the USBHostLite example code, but it fails at HOST_GET_DESCRIPTOR() inside Host_EnumDev().
