216	Crash when accessing USB Hard drive from FreeDOS through the USB Proxy	John Meuser		"I'm trying to do something a bit atypical with VirtualBox, and I think I've exposed a bug in the USB system:

I'm trying to use VBox to boot freedos with USB drivers and run spinrite to scan a USB drive (in this situation my iPod) that is USB Proxied to the virtual machine.  As soon as the usb drivers scan for usb devices, virtualbox crashes.  I'm running VirtualBox 1.3.8 on Linux (Ubuntu 6.10 Edgy) through sudo to get write access to usbfs.

The error I get in the console is:
VirtualBox SDL GUI 1.3.8 built Mar 13 2007 19:25:21

!!Assertion Failed!!
Expression: (null)
Location  : /home/vbox/vbox-1.3/src/VBox/VMM/VMMAll/PGMAllPhys.cpp(886) void PGMPhysRead(VM*, RTGCPHYS, void*, size_t)
Unknown read at 000d2799 size 8 implement the complex physical reading case 201
Trace/breakpoint trap (core dumped)


I'm attaching the floppy image that I'm using (sans SpinRite) and my error log."	defect	closed	USB	VirtualBox 1.3.8	obsolete	usb freedos	meuserj@…	other	other
