chmod usb device?

[mgswed]

Hello. I was wondering how to chmod a usb device automatically when it is plugged in? I have a device that I am using in a jail and when I go to run my program I have to su in order to access it. I would like it to run for the account that is setup and not root. Thank you very much.

In FreeBSD, this is instead configured with sysctl and devfs: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/usb-disks.html.

However, that may or may not work within a jail.

Thanks a lot for the documentation. What I have is not a storage device. I am attempting to run a home automation server from a jail and the USB IO device is on ugen2.2. When I run my program as root everything works fine. When I try to run it as the operator it fails. How do I change the permissions of the device? Does that just involve changing the devfs.rules file?

I'm not sure on that one. If you don't get an answer here, try asking at forums.freebsd.org. Please post the answer if you do get/find one.
