What guest OS were you successful with for storage devices - windows or
linux, 32-bit or 64? I've been mainly using FC-12, x86_64 as the guest
OS, and an external (ie., physical) key of recent vintage. Qemu's msd
device does not work with FC-12 (and UHCI).
I played around with Qemu's usb-net device a bit, but not sure I am
configuring it correctly (using monitor commands to attach).
