Thank you Eric! you were right :-)
I mounted usbfs as root: mount -t usbfs none /proc/bus/usb
usbview works now and most importantly the gnu radio scripts too (but only if 
i am root). the permissions of /proc/bus/usb/* are the following:

/proc/bus/usb:
total 0
dr-xr-xr-x  2 root root 0 Jan 19 17:04 001/
dr-xr-xr-x  2 root root 0 Jan 19 17:04 002/
dr-xr-xr-x  2 root root 0 Jan 19 17:04 003/
-r--r--r--  1 root root 0 Jan 25 04:47 devices

/proc/bus/usb/001:
total 0
-rw-r--r--  1 root root 43 Jan 19 17:04 001

/proc/bus/usb/002:
total 0
-rw-r--r--  1 root root 43 Jan 19 17:04 001

/proc/bus/usb/003:
total 0
-rw-r--r--  1 root root 43 Jan 19 17:04 001
-rw-r--r--  1 root root 43 Jan 25 04:30 044
-rw-r--r--  1 root root 77 Jan 25 04:30 045
-rw-r--r--  1 root root 52 Jan 25 04:30 046
-rw-r--r--  1 root root 68 Jan 25 05:00 048

my id is the following:
uid=500(renato) gid=500(renato) groups=4(adm),10(wheel),43(usb),500(renato)

is there any possibility to run the gnu radio scripts without being root?
thank you again!
