PCAN/USB in use by another process

I'm using PCAN Basic in a windows application. In the event of a crash, or maybe an improper shutdown, The USB adapter stays "in use", LED flashing, and I can not seem to unlock the device and resume short of restarting windows. Is there a hard reset I can do from 1) my app; 2) windows; 3) PCANview; or 4) somewhere else?

If you use the latest Driver Setup, in the Control panel APP you find a TAB to "delete" the open connection from your crashed Application to the driver. See also this thread:

Is it even possible to determine which process us using the PCAN?

the one who load the dll...which is connected to the driver...on a development environmet this could also be a part of the development environment / tools...like Visual Studio. Best is to read the complete text of the post i have linked to.
