Slow LightCrafter USB recognition

I've encountered a very strange problem. When I attach the LightCrafter 3000 to USB port, it always takes like 5 minutes until the software can connect to the device. Once it is recognized and usable, some programs seem to hang unexpectedly: Cannot close task manager, Visual Studio getting stuck unpredictably, sometime I cant even open network connection manager and sound devices. Everything becomes normal when I detach the LightCrafter. Im  currently using Windows 8.1 64bits. I think the problem may be coming from the RNDIS driver, I have it updated but it all still same. Please help me out. Thank you!

  • Hello Van Phu,

    Welcome to TI DLP E2E community!

    Usually since the LightCrafter connects to the PC using the RNDIS protocol, the Lightcrafter gets assigned an IP address and so the connection might take few minutes. However once it is assigned an IP address and you establish a connection with Lightcrafter, everything else should work without freezing up.

    Also refer to section 2.2.4 in the LightCrafter User's guide that talks about fixing the USB- start up delay on Windows.

    Let me know how this and we can take it from there.

  • Hello Manasi,

    Thank you for your response. I have tried to set the static IP address for the RNDIS interface using the GUI (like in section 2.2.4). However, as mentioned above, the GUI was freezing during the process, I could not bring up the Property page. The RNDIS network showed as unidentified network even when the device works fine. I was able to set the static IP address using command line, now the 5 minutes identification is no more but still the freezing problem exists. Im not really sure what cause this, is anybody facing the same situation? Please suggest! Thank you!

  • I have the exactly same issue, I just switched to a new Windows 8.1 machine, when LightCraft is connected to my laptop, the network center in Control Panal does not open or open very slow, and the property page for the RNDIS connector does not open, so I can't change it to static IP. The LightCraft works fine with Windows7 system. Can you share how to set the static IP by using command line?

    Thanks,

  • Hello,

     We haven't tested the GUI or the RNDIS packet transfers on Windows 8 machine. I will work on testing it out on Windows 8 machine here pretty soon and see if I can replicate the issue.

    Thanks for your patience.

    Hello HongSheng,

    To set the static IP for your LightCrafter RNDIS network, you can do the following command (as administrator):

    netsh interface ip set address "local area connection" static static_ip(192.168.1.99) subnet_mask(255.255.255.0)

  • Hello Van,

    I tested the Lightcrafter GUI on Windows 8 machine here. I had to go through following steps to get the connection up and running:

    • Make sure you are using the latest LightCrafter GUI for Windows from Software Bundle 3.0
    • After you connect the LightCrafter to PC, go to Device Manager
    • Right Click on RNDIS Driver and click on "Update Driver"
    • Browse my Computer for driver software
    •  Network adaptors -> Next
    • Pick Microsoft from list of manufacturers and chose Remote RNDIS Compatible device and hit next

    This should update the RNDIS driver and this would have to be done only for the first time connection.

    You should be able to connect to the GUI now.

    Hope this helps.

  • Hi Manasi,

    Thank you for your solution,

    I was able to connect the device to my Window 8.1 machine, and the problem with slow USB recognition was solved by setting static IP for the RNDIS using command line as mentioned above ( I was not able to bring up the windows' GUI adapter setting page, this RNDIS just freezes the task).

    The problem is even the device is successfully connected and I can use any kind of communication, it still freezes the task manager out, u just cant terminate the thing. More importantly, once the device has been connected to the PC, some applications such as: Visual studio, Microsoft Office, ... sometimes hang unexpectedly or could not startup. This is frustrating. I hope there are some workarounds for this.

    Here is what my task manager looks like when I try to terminate it:
