I just started having this problem just a few days ago. As you can see on the pic, naay mga exclamation mark. Di ma detect ang mga usb devices nako. what i usually do to fix this is i disable then enable them pero mu balik gihapon siya ug ingon ani pag reboot nako sa PC.
anyone knows how to fix this?
I also tried uninstalling them and allow Windows 7 to reinstall the drivers but then again, pag reboot, balik nasad ingon ani.
