Hello, I am slightly unsatisfied with user rights management, especially with usb-devices, but also with access to cd/dvd-burners for the following reason: I'd like to be able to allow access to burners that are accessed as scsi-devices (via atapicam) for some users, but for that to work it is not sufficient to allow access via cd0/cd1, but I also have to allow the corresponding pass<x>-devices. For usb-scanner it is even worse. If I allow access to uscanner0, this does not work unless I also allow the corresponding /dev/usb<x>-device. umass<x> is also accessed as da<x>-device and also therefore needs some da-devices to be allowed rw-access for 'ordinary' users. I don't relly like to allow direct access to the related devices (da<x>, pass<y> - especially if the system is using scsi-disks). Is there an easy way to name the devices a user might be allowed to access rw, without compromising the system? I don't want to give operator group to these users, and I don't want to blindly allow access to some da- or pass-devices where I cannot determine the order of numbering easily. I hope this does not sound ignorant. Pointers to helpful information are also welcome :-) Regards, Holger Kipp
