I'm on Mavericks and after I eject most SD cards, it takes a minute or two and process UASysAgent is taking 80% of the CPU… quite annoying, does anyone else experience this? Something that can be done about it?

You can also try disabling Spotlight indexing for the SD card. While the card is inserted go to System Preferences->Spotlight->Privacy->'+' and add the drive.
