My Snow leopard virtual machine keeps on crashing when accessing USB flash disks or external hard disks in latest Oracle VirtualBox 4.0.2. I had the doubt in new chipset PIIX3 support, but that was not the case. Finally, I found the solution to fix this permanently. Its working fine. Here is the simple method to fix snow leopard VM crashing problem in VirtualBox 4.0.2 while accessing USB storage disks.
The crash shows several IOUSBMassStorageClass and AppleUSBOHCI error messages as shown in below error screen. Its related to VirtualBox extension package that enables VB console to support USB 2.0.
Here is the solution
Just install the Oracle VM VirtualBox Extension Pack in your host computer as explained here.
After the installation, enable USB 2.0 under virtual machine settings.
Before start the Snow leopard Virtual machine, make sure extension pack is installed properly and listed here.
Start the VM now and check the USB storage access. I’m sure you will not face the same crashing issue now.
If you are upgrading the Snow leopard to latest 10.6.5 or 10.6.6, DO NOT miss to replace theIOUSBFamily.kext and IOUSBMassStorageClass.kext with older versions. Read this post and comments for more information.
