I got a project using your STM32F103RET6.
I connected it to my PC via USB connector and installed your VCP driver
whose name is VCPDriver_V1.1_Setup.exe downloaded from your web site.
Everything is fine to communicate each other.
However one thing I got disappointment is the one of event,I guess, doesn't poped up from your device driver, which is ERROR_ACCESS_DENIED
from WaitCommEvent() when the cable is hooked out from my PC.
I need to that error number when the device driver is in reset
situation to process graceful exceptional routine.
My program routine has been aleady verified by other VCP manufacturers
such as FTDI and Silicon. Both company's VCP is works well but not yours
so far.
Do I miss something to get that error number from WaitCommEvent() ?
I have to decide whether your VCP is quite working well so that I could
using it on my product.
By that reason I'd like to response from you ASAP.
Thanks
