Hi,

we are experiencing some problems with the STM32 VCP USB driver in combination with windows stand-by. When the computer wakes up from stand-by, we get a blue screen with

BUGCODE_USB_DRIVER The caller has submitted an IRP that is already pending in the USB bus driver.  This is happening with the VCP driver version 1.3.1 on Windows 8 32 and 64 bit. We also generated a driver with the Microsoft WDK, with this driver this is also happening on Windows 7 32 and 64 bit and Windows XP 32 bit.  Did anyone have these problems before? Any hints?  Thanks in advance MaFu

Hi,

Could you provide the USB Trace, this will help understanding the problem.

Which USB library are using ?
