i think I found the reason. It's caused by KSM. I am using koreader which need to install KSM first. Before I installed KSM, everything was fine even I use Calibre to send books with many times.Collection was updated once I unplugged the kobo. After I installed KSM, things went wrong. Collection wasn't updated at once till a reboot. And sometime calibre has problem to talk with kobo.
