found the answer. 

 

I noted that windows update had the Synaptics Touchpad in the optional updates.  I know I installed the latest, so went to look and noted that the mouse was listed as HID compliant mouse vs touch pad.  I reinstalled the touchpad driver and the unknown driver went away.  I'm not sure exactly what the device is as the device ID does not match the touchpad driver.

USB\VID_1242&PID_4058

 

Nothing plugged in other than a netwok cable and power.  No internal additions or upgrades.  Fresh install of Win 7 32 Bit.  All other drivers accounted for.
