How to fix mouse not working after hibernate (USB device not recognized) on Windows 7

I've been having this problem since Vista. And, it's still happening on Windows 7. So, I decided to search around to find a solution. Here is the combined solution that worked for me:

1) Start Device Manager. This can be done (1) by right-clicking on My Computer and selecting Manage. Or (2) clicking the Start menu and typing device manager. Or (3) other ways.

2) Expand the Universal Serial Bus Controllers node.

3) For each instances of Generic USB Hub and USB Root Hub, right-click and go to Power Management tab.

4) Uncheck the option: Allow the computer to turn off this device to save power.

5) Repeat for ALL instances of Generic USB Hub and USB Root Hub.

6) Then, refresh everything by right-clicking and selecting Scan for Hardware Changes. Now, double-check all nodes you've changed and see if any has reverted back to the previous settings. On mine, one of the nodes kept resetting the power management. If this happens, just uncheck the box again and repeat the refresh until it sticks.

7) Retry sleeping or hibernating. It should now resume properly.

If that still doesn't work, you need to change some registry keys.

1) Open regedit. This can be done by clicking Start and typing regedit.

2) Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services.

3) Add new key with name: USB

4) Add new DWORD Value. Name it: DisableSelectiveSuspend with value of 1.

5) Exit the registry editor.

6) Now try it again.

I hope this helps! Enjoy!

This still didn't work for me, it's sometimes unbelievable. As I have a PS2/US2 switch provided with the mouse, I switched back to PS2 and all problems are gone.

Regarding waking up the PC after hibernate, sometimes the USB mouse was working fine, sometimes not... go figure this out when you check the right boxes and fix it in the register :)

My check boxes were already unchecked and the registry entry didn't help either

Change of power management of USB controllers unfortunately did not work. So I went back and changed again the power management option by ticking all the boxes.

Then I tried the registry entry... And surprisingly IT WORKED!!!! Thank you so much!!!
