Ok. after making the modifications as I stated within this thread, I have also now successfully been able to hot-plug and hot-unplug this card.
To unplug this card successfully, you need to first unload the usb
modules used by it:
# rmmod usb-ohci
# rmmod ehci-hcd
# cardctl suspend 0
(or # crdctl suspend 1 depending on which socket# you have this card
inserted. use cardctl config to figure out which one.)
Once done, you should be able to unplug the aua-1420 card (Adaptec
USB2connect card).
It would appear that the /etc/rc.d/init.d/pcmcia script should be
unloading the usb-ohci/ehci-hcd modules but isn't. This is what also is
causing the hangs/freezes at shutdown.
I'm pretty sure now if i added a line within the /etc/rc.d/init.d/pcmcia
script on the "stop)" function (and restart), to unload these specific
modules prior to rmmod pcmcia_core/ds/etc, I will successfully prevent
the hangs/freezes on service pcmcia stop/restart.
