Cannot successfully upgrade Blackberry 9700 OS from within any VM

Question

Here is a rather convoluted description of a problem that I have submitted to Apple as a bug report, as well, but I figured I might as well post it here. I posted this on a Snow Leopard forum and someone there suggested I cross post it here, as well. Maybe someone else has had the same issue, and/or perhaps Apple will pick up on it.
I, along with several other Fusion VM users, and even the VMware people themselves, have discovered a likely bug in the Mac OS when trying to upgrade the RIM Blackberry OS on a Blackberry 9700 from within Windows XP, using a Fusion VM. This does not happen with the Blackberry 9000, only with a 9700. (Another Fusion user has noted the same problem with other BBs which also use a micro-USB cable, as does the 9700, but not those which use a mini-USB cable, like the 9000. I have no idea if this problem is related to the micro-USB or just the different OS on the BBs with the micro-USB.)
The same problem exists for me with a separate Fusion VM on my 2007 Macbook, which has OS 10.6.3 as well.
I have also tested this using a Parallels VM on the iMac, and the same problem occurs in trying to upgrade the BB OS--it acts exactly the same way in Parallels as it does from within Fusion.
There is /no/ problem with the same 9700 and same micro-USB cable upgrading the BB OS on my old Dell Windows XP laptop.
I have /not/ yet created a Boot Camp partition on the iMac and tested it that way.
The problem is that the USB connection with the BB doesn't seem to be stable when connecting from either the Fusion or the Parallels VM to the Mac USB. VMware says it uses standard Blackberry USB drivers in its VM. In any case, when trying to upgrade a BB OS, during the process the initial USB connection is normally lost when the BB is partially "wiped," then regained when the BB tries to boot up in the "wiped" state to prepare itself to load in the new OS. This is when the USB connection fails with the BB 9700 but not with the BB 9000. (The VMs are set to automatically connect the BB to the VM.)
The USB connection is also lost (in the 9700 only, but not with the 9000) when using another BB Windows utility, the Blackberry Swiss Army Knife (BBSAK). After doing a file backup of the BB using the BBSAK, the USB connection is lost, and the USB plug has to be pulled and then reinserted in order to do any subsequent operation with BBSAK.
I'm trying to make the case that this is a compatibility problem of some sort between some Blackberrys, all Windows VMs, and the Mac OS, that is, involving the USB communication between the VM and the Mac OS. I doubt the problem is with the BB or in the BB OS itself, or in the Mac hardware, but I suppose it could be any of these things.
One answer, of course, is to simply use the RIM Blackberry Desktop software for the Mac, which does work fine with the 9700. The problem with that is that the RIM Desktop software for the Mac is limited in what it can do compared to the Windows software for the BB.

It's probably not something Apple would be concerned about as it's dealing with Fusion, Parallels, Windows and Blackberries...none of which are Apple products.
