The website for the Addonics expresscard adapter seems to say that hotswap pci is possible, but probably only in Vista and with the right AHCI drivers.

thanks, , I'll try it again, but I spent like 3-4 hours trying to make it work, restarting and reinstalling:(
and it\'s fairly new PC, quad core, asus MB, XP Pro, anyways, I\'ll try again

as i mentioned, the addonics page says that hot swapping is possible, but "Windows 2000, Windows 2003, and Windows XP are all non PCI-E aware OS and will not support hot swap." this leaves me to believe that it may only be vista that supports the function.

For those that interested i use this,

Newegg.com - SIIG JJ-000082-S1 PCIe to ExpressCard Bay - Case Accessories

it is the SIIG PCI to Expresscard Bay for the pc and fits in the floppy drive bay or other larger bay it reads PCI-E and USB expresscards 34/54, their is a separate cable that plugs internally to the USB on the motherboard and also a cable running to the PCI-E card.
Im running Vista 64 works with no problems its fast.
it is not PCI-E hot swappable. it reads my sony 8gig SxS card from my EX3,
but in order to do so i must first plug the card in and boot up my computer
for it to recognize it because its not hot swappable. Works with USB Expresscard readers
and is hot swappable.
