This is wierd. I've got a multicard reader installed on my Fedora 14 system. If I insert an SD card, it gets recognized and mounted right away. If I unmount the card, remove it, and reinsert it, the system does nothing. No entries in the messages file about the device or anything. If I want to use the SD card again, I have to reboot.
Has anyone seen something like this before? Ideas on how to debug the problem?
