For my system, I have to specifically rmmod all the modules associated with the device before removing it. I have written scripts to help me. E.g "eject-nic" that is for ejecting the Network interface PCMCIA card. Also, "eject-camera" etc. I think people will have to wait until kernel 2.5.x or above for better plug-n-unplug support. Maybe I am wrong, and it is just a co-incidence that all the devices I have had bugs in the drivers.
