It appears that on some host USB configurations(2012 MacBook Air) multiple restarts of openocd tool cause the FW on STLINKv2 dongle to go into a weird state in which it will no longer respond to STLINK_GET_VERSION command. This patch adds code that, if said request fails for the first time, attempts to reset the device and retry to initialize it and obtain FW information one more time.
