I am attempting to put the PC into Standby (Suspend or 'hibernation' mode), but I receive an error from the CP210x driver. What is wrong?
Answer
Earlier versions of the CP210x VCP driver purposefully did not allow the PC to enter standby mode when a handle to the CP210x was open. If the PC attempted to enter standby while the handle to a CP210x was open, the following message was displayed:
The VCP driver did this to prevent any errors from occuring during the Standby process (blue screens).
In order to place the PC into Standby when a CP210x was connected, the application had to close the handle to the CP210x. The application did this after any long idle period (please see this article for information on using the built-in Windows Timers).
