The dummy-hcd driver was intended for testing and development. It's not useful for much else in the real world, because it only simulates a USB connection. It doesn't allow you actually to connect your computer to anything else. > Here is a snippet from /var/log/messages. I have changed the backing > store to be a seperate disk, i.e. hdd1. Yes, that's how dummy-hcd works. In effect, it makes a single computer behave like both a host and a peripheral. > > > Now I want to turn one Linux PC into a Mass Storage device.

No more than any other serial connection would. If you want to interconnect two PCs, you're probably better off using Ethernet. Then you could share mass storage devices via NFS or iSCSI, and you could do lots more in addition (like remote login). > Basically, I followed the g_file_storage how to that was on the > linux-usb web site. > > Now I am attempting to extend that howto into mounting the > g_file_storage mass storage device from another PC via a USB cable. > > So...Is this even possible with the ICH5 USB controller? No. USB hardware comes in two distinctly different flavors: host and peripheral. The USB host controller hardware on your PC is not capable of acting as a USB peripheral. If that's really what you want to do, you can buy USB device controller hardware. There are PCI cards you can install in a PC that will act as a USB peripheral.
