VMWare USB breakage

[Trevor Blackwell]

I'm working on a new driver for empia 28XX USB cameras, and since it  
needs isochronous support I'm upgrading to HPS's new stack. However,  
it doesn't seem to work at all under VMWare.

I'm running yesterday's checkout of RELENG_8, under VMWare Fusion  
1.1.2 on a Mac 10.5.8 host. That setup has worked well for me in the  
past developing USB drivers with the -7 kernel. But when I plug in  
various things, it can't even seem to set an address.

Here's what I get from dmesg with hw.usb.debug=8 when I plug in a new  
device:
