So I went to update the software on my Nokia 770 (only works with Windows, which blows) and ran into what is apparently an existing USB problem with Parallels -- the virtual machine will not detect a USB device and then tells you that there is some other service that's using the device, suggesting that you manually locate the service and un-hang the device.
In Googling about this it seems that Parallels is aware of the issue, but there are no really good solutions at this point.
For what it's worth. Good thing I still have a crappy Windows machine around to take care of these kinds of issues.
