Access Gembird USB device as non-priviledged user

[Rainer Dorsch]

Hi,

is there a good way to access a Gembird USB device as non-root user?

I have

rd@blackbox:~$ lsusb -v -d 04b4:fd13

Bus 004 Device 002: ID 04b4:fd13 Cypress Semiconductor Corp. Programmable

Couldn't open device, some information will be missing

rd@blackbox:~$ 

and tried

rd@blackbox:~$ cat /etc/udev/rules.d/z61_sispmctl.rules
SUBSYSTEM=="usb", SYSFS{idVendor}=="0x04b4", SYSFS{idProduct}=="0xfd13", 
ACTION=="add", GROUP="sispmctl", MODE="0664"
rd@blackbox:~$ 

but this does not seem to have any effect

rd@blackbox:~$ ls -l /dev/bus/usb/004/002 
crw-rw-r-- 1 root root 189, 385 Okt 31 12:02 /dev/bus/usb/004/002
rd@blackbox:~$ 


Is there something I am doing wrong or is there a better way to do this?

Thanks
Rainer
