How to pass USB cell phone modem to Windows

[dm3]

I'm trying to let the WIndows guest OS have access to a LG Fusic cell phone connected via USB. It shows up in the list of devices I can attach to Windows, but when I attempt it, it says that the device is in use and try again later.
As far as I know, its Mac OS X's networking which may have accessed the modem and lists it as an option for new connections.

Is there a way to tell Mac OS X to stop using the USB device so that Parallels can use it for Windows?

Alternatively, if I do dial into the network using the phone and the Mac, is there a way that Windows can use that network connection? When I try that Parallels only shows ethernet and Airport as options.

This is on a new Intel Macbook.

Thanks

Use host only networking.

I posted this in another thread -- it sounds like a lot of people are having this kind of issue, although if it works for you to use the Mac's dialup stuff, that's much better than this. Let me know if this helps...

So I know I'm in the minority (with Jerry here), but I actually do need my phones to punch through to Parallels without being interfered with by the Mac, so I can do BREW development.

The only way I've found to allow this is to remove the kernel extensions that handle CDC (Communications Device Class) connections. They're easy to find; just go to /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns. Everything in there that's called AppleUSBCDC*.kext needs to go. I suggest you back up the entire IOUSBFamily.kext before you try this. Reboot and everything should work. Please be careful, it would be very easy to screw things up.

This will disable USB modems (and cable modems) and will prevent you from using your phone as a tethered USB modem. I'm not sure if it affects Bluetooth dialup, but I don't see why it would, I'll try it out at some point. You can put all the extensions back if you need them and everything will start working again.

But now I am able to get my v3c to show up under Parallels. Awesome!
