Duplicated OUT report in HID

Question asked by palitsky.gennady on Jun 24, 2017

I am developing HID application on STM32F427 with STM32_USB-Host-Device_Lib_V2.2.0

Works mostly fine, but once in a while (quite often, actually), when Windows app sends command to the controller (OUT report), it's duplicated - the second report is sent right after the first one.

I remember discussion on fixing a problem related to usb interrupts in lib_V2.1.0 in old forum.

Cant't find it now. And not sure it's related to my problem or lib_V2.2.0

 

Any suggestions on what can cause such behavior?

 

Thank you
