D600: bluetooth dongle causes blue screen

i just recently purchased a docking station for my system after making due without one for the last couple years. the reason for this purchase as centered around having usb 2.0 ports. my D600 only has 2 slots being 1.1 and after the purchase of an external dvd burner last year i started to understand the limits this would cause in the future. my answer was to buy a usb 2.0 PCMCIA card which solved the poor dvd quality playback due to slow data transfer. this causes a problem when i use that PCMCIA slot for my wireless router card huh? now i have a sprint wireless broadband aircard so yes that slot is pretty much used all the time. i make my phone calls using my pc and wires annoy me (probably as much as callers on the other end hearing their own echo) so instead of using headphones i just decided to buy my first bluetooth device; a motorola H500 headset. i was under the impression that my d600 was originally shipped with an internal bluetooth card but not having any devices to test i didnt know any better (having the radio Fn+F2 on all models is misleading to the noobs). so yes i couldnt do anything until i went back to the store to purchase a usb dongle. everything seemed to be fine and for the mostpart i was happy with the purchases until ppl on the other end of my calls started to complain about stuff like, slight static sound, it sounds like theyre on speakerphone or the biggest issue on my end being some sort of lag that maaaaddeee eevverryyonne sooouund liiikee.. heeeyy aarreee yooouu stillll heeeereee?. lol.. its a usb 2.0 dongle in a 1.1 port. maybe thats part of it. my 2GB of memory are in the mail too but none of that is why i'm posting this thread. i have a couple questions about this bluetooth dongle. first, why the hell does this dongle need to reinstall drivers for every individual port (i tried both onboard ports and both pcmcia card ports)? to avoid this i have to remember which port i installed it at originally and keep plugging it into that one in the future, which seems retarded. secondly and the most important, my docking station will not see the dongle when hot swapping, only when i leave it in one of the 4 ports and reboot the system will it recognize and start installation of drivers, but here's the catch.. the last driver that is installed (i cant remember the device off hand, but its not 'generic usb to usb2 hub' its the last 1 of 3.. upon installation BAM i get a minidump error.. system blue screens and reboots. its the same for any one of the 4 ports on docking station. i'm upset about this and if i cant get any support or help i'll probably just return the dongle (which is a bluetooth bluespoon btw) and possibly try another brand / model OR see what i need to do to install an internal bluetooth card. i'm not sure if my older model d600 will even allow it. please help and thanks for reading this lengthy post.
