I moved that file to another location and rebootet. Now there are no more /dev/cdrw or /dev/dvdrw links anymore but all the usual files and procfs contents are there. See logs below. As next I rmmoded usb-storage, ehci-hcd, ide-cd and reloaded them again, now some extra links have been created but they are called /dev/cdrw1 and /dev/dvdrw1. Still no /dev/cdrw there. My impression is that it always takes the X string part from cdromX and appends it to cdrw, resulting in no "cdrw" symlink if "cdrom" has no writting capabilities. If I am right then... uhm, it sucks and should be changed ASAP. A setup like mine (first drive a pure reader and the second is the writter) is not that uncommon. And it still does not explain the failure after rebooting. > > I think we have a problem here.

This is a laptop with a DVD-ROM drive and a DVD-RW recorder attached via USB.
