Duplicated OUT report in HID
Posted on June 24, 2017 at 19:12
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
