Folks,

I have written EPICS device support for a USB device (Saturn spectroscopy system from XIA).  It is working fine under both Windows and Linux.

However, on Linux I have been running the IOC application with root privilege, which I would like to avoid.  The problem arises because USB devices are created dynamically, so one cannot statically give them the desired mode (e.g. 666, 660, etc.).

My understanding is that one can use the Linux "udev" facility to handle this.  I've found some examples of how to do it on the Web, but I can't seem to get it to work.  I was hoping someone might be able to tell me what I'm doing wrong.

I've created a file, /etc/udev/rules.d/80-saturn.rules

[epics@baja rules.d]$ more /etc/udev/rules.d/80-saturn.rules 
SUBSYSTEM=="usb_device",ACTION=="add",ATTRS{idVendor}=="10E9",ATTRS{idProduct}=="0700",MODE="0666"
SUBSYSTEM=="usb_device",ACTION=="add",ATTRS{idVendor}=="10E9",ATTRS{idProduct}=="0701",MODE="0666"
This should set the permissions on the device to 666 when the USB device is added.  I have verified that these are the correct idVendor and idProduct with udevinfo:

[epics@baja udev]# /usr/bin/udevinfo --attribute-walk --name=/dev/bus/usb/005/008
Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
  looking at device '/class/usb_device/usbdev5.8':
    KERNEL=="usbdev5.8"
    SUBSYSTEM=="usb_device"
    DRIVER==""
    ATTR{dev}=="189:519"
  looking at parent device '/devices/pci0000:00/0000:00:1d.7/usb5/5-1':
    KERNELS=="5-1"
    SUBSYSTEMS=="usb"
    DRIVERS=="usb"
    ATTRS{product}=="EZ-USB"
    ATTRS{manufacturer}=="Cypress"
    ATTRS{quirks}=="0x0"

    ATTRS{version}==" 2.00"

    ATTRS{busnum}=="5"
    ATTRS{speed}=="480"
    ATTRS{bMaxPacketSize0}=="64"
    ATTRS{bNumConfigurations}=="1"
    ATTRS{bDeviceProtocol}=="00"
    ATTRS{bDeviceSubClass}=="00"
    ATTRS{bDeviceClass}=="00"
    ATTRS{bcdDevice}=="0000"
    ATTRS{idProduct}=="0701"
    ATTRS{idVendor}=="10e9"

    ATTRS{bConfigurationValue}=="1"
    ATTRS{bNumInterfaces}==" 1"
    ATTRS{configuration}==""
    ATTRS{dev}=="189:519"

I've increased the debugging level of udev, and restarted udevd.  I can see in the log file that it has read my rules file.

However, when powering the Saturn off and on (and thereby creating a new Linux USB device), the permissions are not what I want, they are still 644, not 666.  If I manually change the permissions on /proc/bus/usb/005/008 to 666 then non-privileged users can run the IOC application.  But the next time I power off and on the device, it will be device /proc/bus/usb/005/009, and again I would need to log in as root to change the permisions. 

Here is the output of the log file when the device is powered on and found by Linux.
