permissions on libusb

Hi guys,
Just reloaded my linux box with ubuntu 12.04 LTs and reloaded oscam with smargo support back on it. All seems to go well but when it tries to open smagro I get this error...

2012/06/13 15:14:48 95C62B8 r libusb_open error LIBUSB_ERROR_ACCESS : the user has insufficient permissions
2012/06/13 15:14:48 95C62B8 r Smartreader device 001:005 not found
2012/06/13 15:14:48 95C62B8 r Cannot open device: 001:005
2012/06/13 15:15:48 95C62B8 r Using 0x82 as endpoint for smartreader hardware detection

2012/06/13 15:15:48 95C62B8 r libusb_open error LIBUSB_ERROR_ACCESS : the user has insufficient permissions
2012/06/13 15:15:48 95C62B8 r Smartreader device 001:005 not found

Not too brilliant on linux but it seems there is a permissions issue anyone give me a clue as to what to change to fix this. cheers guys

Cheers lfc that sorted it but how do I make sure it stays and oscam runs as root?

would this be because when I ran the install of oscam I wasn't signed into root ie. sudo -i as you can see below I ran everything when in steve@steve with sudo prefix not root@steve. If I run it all again whilst in root will this fix it?

steve@steve-Aspire-R3600:/usr/local/bin$ killall -9 oscam
steve@steve-Aspire-R3600:/usr/local/bin$ sudo -i
[sudo] password for steve:
root@steve-Aspire-R3600:~# oscam -b
root@steve-Aspire-R3600:~# ^C
root@steve-Aspire-R3600:~#

sorted did this......
sudo pico /etc/rc.local
then added this.......

/usr/local/bin/oscam -b -c /usr/local/etc/ &
