In my experience, umass over EHCI has never worked on any machine ever, going back to 5.x and over multiple kinds of umass devices. (I never saw panics, only triple-fault CPU resets.) My old workaround was to disable EHCI in the kernel configuration, but in 7.0 umass just doesn't work (reads corrupt data, even without going through a filesystem). The same device works fine in Windows. (In fact that was the workaround I had to resort to during a recent trip.) FireWire has always worked for me, but consumer A/V devices don't come with FireWire ports, and my 7.0 machine is a USB-only laptop. (I can plug a CF card into my FireWire CF reader and get valid data off it on my 6.2 desktop, whereas the same CF device fails on the laptop under 7.0. It worked when the laptop was running 6.2.) -GAWollman
