VNC2 cannot enter "ENUMERATED" status.
« on: June 11, 2018, 02:42:48 AM »
Hi ,

I'm using VNC2 for CDCmodem. ( and using CDCModem.zip sample code )
I have found the VNC2 cannot enter "ENUMERATED" status if usb modem device be inserted before VNC2 power on.
When ioctl_code = VOS_IOCTL_USBHOST_GET_CONNECT_STATE,  return code is "PORT_STATE_CONNECTED" always.

Anyone comment ?  Thanks.

Hi ,

Actually, i dont understand your comment.

Because my testing is base on your EVK board ( V2DIP1-32 ), source code(cdcmodem.zip) is sample code from your website, too.
I only insert USB modem into EVK, and start debugging/running test code by "Vinculum II IDE".   

Why cannot be ENUMERATED (usb modem be inserted before start running) ?   The testing code have no tested on your EVK board ?
Or the issues is limited on your platform ?
