Hello,
I’m developing a USB composite device on STM32 that combines RNDIS and CDC interfaces.
The device works perfectly the first time it’s connected to a Windows 10 PC — both RNDIS and CDC functions operate normally.
However, after I reset the MCU or power-cycle the board, Windows shows the following error in Device Manager:
“This device cannot start. (Code 10)”
{Operation failed} The requested operation was unsuccessful.
At this point, the RNDIS interface no longer works.
If I uninstall the device from Device Manager or reinstall the driver, it starts working again.
On Linux, the same device works without any issue, even after multiple resets.
I have confirmed the following:
The USB VID/PID remain the same after reset.
The device descriptors are correctly reported.
The problem occurs only on Windows after a full power cycle or hardware reset.
Has anyone experienced similar behavior with RNDIS composite devices on STM32?
Is there something specific I should check in the USB descriptors or RNDIS initialization sequence to prevent this Code 10 issue after reset?
Any suggestions or known workarounds would be greatly appreciated.
Thanks in advance,
