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?
Dumb question - are you unmounting it, or using safely remove hardware. In the later case, it is not uncommon for the entire reader to be turned off.
For an external reader, you can unplug it, and plug it back in. For an internal reader, you may be able to get it working again by running, as root:
modprobe -r usb_storage ; modprobe usb_storage
If you have other devices using the usb_storage module, it is not going to let you remove the module.
