Eventlog when USB Device connected

Hello,

I've got a virus alert message from a client in our network.

The drive letter of the infected partition points me to an external usb
device.

To be sure I would like to know if it is possible to see in the eventlog or
somewhere else when an usb device was connected.

I couldn't find anything in system or application log yet.

I had switched on auditing for the security log. May be I can find
something there what could give me an idear when such an event was occuring,
but don't know for what I could search for.
