Hi Naoki,

Please describe your problem what doesnot work? on USB.

Did you mean that you configured the OMAPL137 to act as a USB device and connected to the Windows host machine; Which detects the OMAPL137 as a USB device?? and when you connect it to a Windows server, it gives problem???

Hello Shankari,

Thanks for your reply. I think your understanding is correct, but I'm trying to get more detailed information from the customer. I'll update you later.

Hello Shankari,

Some updates to you.

OMAPL137 system works as a USB device (Linux USB Ethernet/RNDIS Gadget) and it is connected to Host PC. In case of Windows server 2003 and Windows7, OS finds/installs linux.inf driver file and the system works correctly. But in case of Windows server 2012, OS finds linux.inf but fails to install the driver. I got a picture for the error window, but it was in Japanese... I seem the error indicates that driver installation failed because of no digital signature in linux.inf file.

Do you have any suggestions ?

Best Regards,
Naoki

Hi,
I hope, we can try to enable the "Digital signature disabled" option in windows server machine to install such a old drivers.

Try to use the following command to do that through command terminal.

bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit /set testsigning on

Can you try this please.

Hi Naoki,
Any update from customer ?
Able to solve the issue ?

Hi Titus S.

Thanks for following up on this issue.
I've answered the same to the customer and I'm still waiting for their response.
I'll update you later.
If the above suggestions solve their problem, I'll mark this thread as verified answer.

Hi Titus S.,

Unfortunately, the answer you suggested did not help... I'm asking their current status, but they are saying it would take much time to summarize their status. I'll update you once I got any information.

Naoki

Hi Naoki,
Thanks.
If they are getting "digital signature" problem then the above step fix their problem.

Hello Titus S.

Sorry for the long delay.
Finally, they could confirm the default RNDIS driver provided by WindowsServer2012 worked correctly.
But the customer are not sure if this is recommended or not.
Can you comment on this ?

So here is Host machine configurations:
Open device manager --> network adapter --> property --> update driver software --> select network adopter --> select Microsoft RNDIS compatible device

Hi Naoki,
Thanks for your update.
I can't comment which I didn't work, also we never tried this with Windows server.
Please let me know if any issues with this configuration.
