The AppleVSP.kext kernel extension has been giving me headaches lately. It doesn't load on any of my machines in Tiger, and neither on most OS X machines I've looked at. On a few of my BootCD testers' machines, however, this extension does load, and on all of those machines, boot CDs made by BootCD either kernel panic on boot or fail to load the login window.
The machines that use this kext seem to be mostly iBooks and PowerBooks, but I can't figure out what is special about them, because I've looked at an iBook and a PowerBook, neither of which used AppleVSP.kext. The extension does not seem to be part of the basic Darwin distribution, and I can't find any source or documentation for it.
Anyone have any idea what AppleVSP.kext does?
Thanks,
Charles

Something to do with the motion sensor? Just a guess.

That was my thought, too, since two of the machines did include the SMS. However, my sister's iBook didn't seem to use AppleVSP, and it's brand new, so it ought to have the motion sensor. Also, one of the testers who had a problem with AppleVSP had an iBook 800, which I don't believe has the SMS.

I beleive only the Powerbooks have the motion sensor. iBooks don't have it.
ktext files can be opened with a text editior. open it up and you should be
able to tell what it does

Uh, no.
What the heck is a "ktext" file?
CharlesS is talking about a ".KEXT" file (no extra T), kernel extension file. Kexts are compiled code, so opening one in a text editor won't tell you jack s*** about what it does.

And one more for you:
The current generation of iBooks DO have the sudden motion sensor.

Actually he was partially right, you can open a kext files plists in a text editor

Person Man was also right — it doesn't tell you jack **** about what it does.
We're all right!

I think it's an IOKit driver.

Some Googling reveals: VSP = Virtual Serial Port (or Virginia State Police, so take this with a grain of salt).
Might it have something to do with Bluetooth connections (esp. to phones)?

My iMac has Bluetooth, and doesn't load that driver. Strange. I don't have a Bluetooth-compatible phone, though.
Could anyone with a Bluetooth phone check their System Profiler and see if AppleVSP is loaded under Extensions?

I'm the iBook 800 guy you mentioned. I do have a Bluetooth phone, but I never managed to get it to sync. Regardless, I suppose that could be it. I'll check to see if that kext is loaded when I get back home.
Edit: Yeah, it's loaded.

If it truly is a Virtual Serial Port, my guess is it has somehting to do with a software modem. Modems are serial, after all, and if you're faking a modem in software, "Virtual Serial Port" is a decent name for a piece of software involved in that. I guess it's only loaded if there is a software modem present, or a particular version of one.
EDIT: I have a bluetooth phone, and I've synced it and had that network interface active (though not in use). AppleVSP is not active on my iMac G5.

AppleVSP is loaded here, and I do have a BT phone. I don't really use BT, however, and it mostly stays deactivated.

Ditto except I use Bluetooth synching etc very frequently with my phone.
