We had an issue similar to this but with serial connected printers. We basically had this old, TN3270 type system that required printing to a serial, dot-matrix printer.
In the end we modified the CUPS startup script to first check for permissions on the devices, and if they were incorrect, set them to what they should be. ...this was on RedHat 7.3 though... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brian Henning Sent: Thursday, August 24, 2006 9:58 AM To: Triangle Linux Users Group discussion list Subject: Re: [TriLUG] Serial usb devices permissions hot plug question on Rel 4 I think the "right" way to handle this issue is to ensure that every process that needs to access the device be run under a user who is a member of the group owner of the usb device. Nevertheless, I'd be interested in hearing another answer to this too, since I can't seem to get CUPS to run as the right user that has rw access to my USB printers (and end up manually setting o+rw on /dev/usb/lp* after every reboot and/or hot plug). ~Brian Ralph Blach wrote: > I have USB serial adapter which I plug into my redhat Rhel 4 system. > When USBserail port is plugged in, its permissions are always gu+rw > but not other. > > Where do I modify hotplug or the USB conf files so the USB serial port > which are plugged in will have there permissions set to guo+rw? > > Thanks > > Chip -- ---------------- Brian A.
