I found some info, though it doesn't look like the full details are publicly known. The device shows itself as two devices and indicates different types for each so that one looks like mass storage and the other a cd drive. It is suspected that nonstandard scsi commands are required to write to the cd device. Some people have tricked one of the available tools into loading custom isos into the cd portion of the device. So it looks like you do need a special tool if you want to have the space initially reserved for the cd image released for use in the normal part. Probably theer is some secret scsi command to do this that wouldn't be too hard to find if someone were serious about figuring it out. Why anyone would want one of these devices is beyond me. It's a security nightmare for both the computer being used (due to autorun being enabled) and the usb device owner (due to not just running code from the device). If you own both, there is no reason to have that feature. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
