Hi!
We have developed a USB 3.0 camera with the FX3 kit as the basis. Occasionally, in some cameras, we get the FX3 automatically switching to Serial MFG mode instead being enumerated as a Composite Device in Device Manager in Windows 10 x64. This happens unpredictably, and may happen once in 2-14 days. Can anyone help with what could be the potential cause of this problem, and what we need to do to resolve this?
Thanks and Regards,
R A

Hello,
Can you please let us know whether you are using 2 interfaces. That is UVC + another interface or UVC + the internal debugger in your application.

Hi Jayakrishna,
We are are using a single UVC interface (we have only modified AN75779) in Release mode.

Hello,
Does this issue occur when you use some specific sensors only or does it occur with all the sensors. Also can you let us know whether you are using a custom board or not.

We have developed and are working with only one sensor. And it is a custom board, not the FX3 kit board. The problem occurs unpredictably, and in some cameras only.
Thanks

Hi Jayakrishna,
Kindly give me some time. As this is an unpredictable problem, I am waiting for it to recur in one of the cameras we have deployed. The moment that happens, I shall gather the above information you have requested and get back to you.
Thanks and Regards,

Hi Jayakrishna,
Thanks for the quick response. I am in the process of implementing it. However, I cannot be sure until we test for extended periods if this has worked! Therefore, I would like to ask the following -
1. Will it eliminate the default setting as MFG mode?
2. Will it prevent the FX3 from going to MFG mode at any time during Windows booting/running/shutdown?
Thanks and Regards,
Narayanan
