Wireless USB mouse disabled after returning from standby

Whenever I return from standby mode, the mouse doesn't work, only touchpad. Everything else works. Have to reboot to get mouse back. log off/log on doesn't do it.

Possibly tweaked in this "feature" or defaulted to this setting after mouse software/driver update. Don't know/recall any "cause -> effect" relationship. Didn't do this historically, but don't remember when it started. Hibernate is disabled by choice.

Must be a setting somewhere to fix this, looked in mouse control panel and googled for info, no luck.

BTW , I already have HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usb
“USBBIOSx”=DWORD:00000000(0)

This is the correct setting according to:

Anyone here have the answer? How about a reg key(s) and appropriate setting?

Inspiron 9400/E1705, XP Pro, sp2, Intel Core 2 Duo 2.13GHz, 4GB Ram, 120 GB EIDE SATA Hard Drive (7200 RPM), 256MB ATI MOBILITY RADEON X1400 HyperMemory, moderately tweaked

 

this might work:

In the Device Manager window, expand Mice and other pointing devices, right-click the mouse that is listed, and then click Properties.
On the Mouse Properties page, click the Power Management tab, click to select the Allow this device to bring the computer out of standby check box, and then click OK
