ST-Link/v2 intermittently stops working and must be disconnected and reconnected to USB port. Is there a way to fix this behavior?

on page 95 of manual UM2237 (STM32CubeProgrammer command line interface (CLI) for MCUs) there is a reference to a "programming manual" and a "reference manual." Can you tell me how to acquire these? I can't find them on the web site.

Is there a list of messages that includes a description. For example: "No ST-LINK detected", "No ST-LINK ready to use" or "Old ST-LINK firmware/ST-LINK Already Used"

In ST-Link32 Utility, Read Out Protection is Disabled, but I get the errors: The elf loader Program function fails. Memory-Loader error Error occured during program operation Programming error @ 0x08000B60!
