Hi, folks.
My USB ports have stopped powering my mouse. I'm thinking maybe the regulating cap is toast.
Here's a picture of the cap which sits just behind the USB module on the backplane:


I'm pretty sure it's a Nichicon FPCAP, although I could use help with the markings.
6.3V is obvious, and I think that "561" means 56x10ยน (i.e. 560μF) but I don't know what 781 means.
I've downloaded the FPCAP catalog from Nichicon's website but I can't find a numbering scheme that matches the markings.

Help a brother out?
