I have some troubles with my Windows 7. It detects USB devices (flash, mobile, etc.) perfectly if I didn't use hibernation mode before. However in case Windows wakes up after hibernation it can't detect USB devices. I just plug a device into USB and nothing happens. Only reboot helps.
MB: MSI H55M E33. OS: Win7 Pro x64.
Could you give some advice to resolve the issue? Thanks.
UPD: I've found that USB connectors on the back side of my computer work properly. The issue relates to USB on the front panel.
