Hi aka313, You can try the following steps: Check the "USB selective suspends settings" option in the Power Options. Important: This is a default power setting, disabling this setting will cause additional battery power consumption when your mobile PC is in Sleep or Hibernation mode and unplugged. If this does not work, you can uninstall USB root hubs from your computer. Uninstall USB root hubs from computer: Note:  If you are prompted for an administrator password or confirmation, type the password or provide confirmation. If the issue is still not resolved, you can update the Chipset drivers for your computer. You can download the chipset drivers for your computer from the link below: Steps to download drivers:- Please reply in case you have further questions.
I have searched the forum and various other sites and have not been able to determine the solution to this problem. The issue is the following:  When I put my system to Sleep mode and then wake the system to resume, all of my front panel USB ports and Media card readers slots are not available for use (and not visible in the Device Manger).  There is power going to the ports, as when I plug in a portable drive it will power up, but will not be registered, as the USB is not visible.  They are only visible after a reboot of the system.  I've already unchecked "allow to turn off the power" in the Power Management tab in the Device Manager and turned off the logging in the BIOS settings.  Are there registry settings or the power configuration settings that need to be enabled/disabled? I have run out of ideas on what else can I do to get the front panel ports working other than rebooting the system everytime I need to get access to the front USB ports (which is very annoying).  My specs for my XPS 8300 are the following: Intel i7-2600, with 12 GB of RAM, 1 TB HD in RAID 0,  DVDRW/BD, ATI HD 5670 - 1 GB, Windows 7 64 bit Home, DELL P2411H Monitor, BIOS updated to A06
