Hello,I'm using a Fujitsu-Siemens Esprimo P5909 computer and preinstalled english Windows XP Professional SP3, with hungarian language pack. My problem is that if I hybernate the computer, when I restart it, the USB ports are not working: the printer or the memory stick don't appear to be conected. This issue can be resolved in two ways: restarting the computer or disconnecting the connected devices, entering the computer in stand by, open it again and reconecting the devices. In this case, everything become ok, devices are recognised and works well. Do know somebody how this error can be fixed?Thank you

Hello,Thank you for your answer.· There are 6 USB controllers (are 6 USB Root Hub elements in the Computer Management)· Yes, I installed updated drivers (I hope the driver is the good one, I found it using Driver Genius).I made the settings you described me, before your answer (I found this somwhere in a Microsoft article), but doesn't helped.Thank you,Balazs Laszlo

OK, I found a solution: I changed a BIOS settings: Advanced - Peripherial Configuration - USB BIOS Supported Devices changed to None. Now everythink works fine: the USB ports works well after resuming from hibernation. I don't know what this setting is, but it fixed the problem.Thank you
