Have a new problem now, my gridseeds were working in cpuminer, now they arent working with any software and are not showing up as COM ports in device manager anymore, they are showing up as "STM32 Virtual COM Port"......
Did you try to install cgminer and the zadig drivers. Are the st devices showing up under com ports in the devices tree or somewhere else. If there somewhere else re-install the St drivers. should make them com port compatible again. The idea is to remove zadiag drivers and replace them with the st drivers again.
