>From a software point of view you are just writing to the /dev/rcd* device, so any standards-compliant USB BD-R drive should work. Like any USB peripherals, there are probably some stupid ones that don't or would require tweaks to the kernel to be recognised, etc. Having said that, for maximum reliable operation you need a sustained data rate up to ~50 Mb/sec, and I wouldn't entirely trust USB for that. Any reason why you particularly want a USB one? If I wanted a reliable external BD-R drive that I could move between machines, I'd probably put one of the Pioneer ones in an external eSATA enclosure. The one Asus drive I tested had a few quirks, BTW, so I wouldn't be inclined to invest in one of those.
