RNDIS connection is forbidden automatically

Hi

    My LCr is working fine most of the time, but sometimes, the connection between LCr and PC is dead. The connection (Local connection2, Remote NDIS Compatible Device) is forbidden automatically, and I can't enable it unless I reboot the computer. Power off and then on the LCr dosen't help either. This situation occurs if I don't  send command to LCr for a while.

   Firmware version: DM365 5.0   

                                FPGA  2.6.43

                                 MSP430  3.0

 OS: WIN7 32

Has anyone seen this before?

    Hi Will,

    Can we find out more information about your setup?

    1. When the connection 'dies' has the LightCrafter been left in the 'Connected' state?
    2. Does the GUI still show 'Connected' when the LightCrafter is not responsive?
    3. Is this a desktop or laptop?
    4. Where are you seeing the message about the connection being 'forbidden automatically'? Can you provide a screen shot of this message?
    5. Can you provide the output of ipconfig /all for the LightCrafter (RNDIS gadget) as well as the IPv4 properties for the LightCrafter. These instructions can be found in the LightCrafter User's Guide section 2.2.4 Fixing the USB Start-Up Delay in Windows
    6. How did you install your RNDIS driver? Did you follow the instructions in section 2.2.2 Installing the RNDIS Driver on Windows 7?

    Can you also try the following steps to reconnect with the LightCrafter

    • Power down the LightCrafter
    • Unplug the USB connection
    • Close the GUI
    • Reconnect the USB cable
    • Power on the LightCrafter
    • After the system boots (RGB bars projected), open the GUI
    • Click the 'Connect' button on the GUI

    Thanks,

    Clinton

    Hi Clinton,
       Thanks for help.
       I find this error when I use my program(based on the sample code) to project patterns. So
       1. When the connection dies, I'm not sure whether LCr is left in "connected" state. When it happens, my program dies as well, and I close it in process manager;
       2. The GUI won't be able to connect to the LCr anymore, it shows "command processing"
       3. A desktop with Win7 32bit OS;
       4. The connection is fine at first, and the connection is shown as "local connection 2" in the network adaptor, when it goes wrong, the state of "local connection 2" is "fobidden", and I can't get it to work again;
       5. The ipconfig /all of RNDIS:192.168.1.99,255.255.255.0; the IPV4: 192.168.1.99, 255.255.255.0
         6. Yes, I installed the driver exactlly based on the instruction.
    I did close the GUI and reboot the LCr, it didn't work, but not the steps as you suggested. Reboot the PC works. I'll try your steps when the problem occurs again.
     
    Thanks
    Will
