my usb ports stop working after resumeing from hibernate or sleep
i upgraded my OS from windows vista business to windows 7 ultimate ,and after the upgrade every thing was working fine
after a while when my computer resumes from sleep or hibernate all of my USB ports stops working!!!
and also when this happens I try to restart or shutdown my computer it just goes for ever and i am forced to a manual shutdown with the power button
i am using a lenovo T61 Laptop ,and my OS is fully updated
so i guess that i need some help here ... please.

As well as disabling power management on the USB Root Hubs, try upgrading the chipset driver - eg from Intel's site directly if it uses an Intel chipset.
IBM/Lenovo has many issues with Windows 7. Mainly because of BIOS problems. Go to the Lenovo support site http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67853 and download and install the latest BIOS. It corrects many issues related to problems with Windows 7.
This said, be careful. Follow the instructions to the letter. Really! A failed BIOS installation can ruin your computer.

well i already tried this update
http://support.microsoft.com/kb/941600
it works only for vista.
but the solution (usb root hub/properties/power management and uncheck
to allow computer to disable to save power) works fine until the first restart of the computer.
and i can concider it as a temp solution if i decide to keep my computer in hibernation with out any shutdown or restarts.
because when you restart you have to go back and uncheck them all .... !!!!!
so i figured this solution:
because of the windows power plans ,USB ports are by default enabled for suspend .
so when you restart the (allow computer to disable to save power) check box is checked again
so this is what i have done:
1.control panel
2.power options
3.click on (change plan settings) of the active power plan
4.then click on (change advanced power settings)
5.for each power plan in the drop down list expand USB settings and then expand USB selective suspend settings and then chagne both modes (on battery ,pluged in) to disabled
every thing is now working great
thank you all for the help
