I have my program working OK but need to run as sudo.
So now I am trying to get the program to run in user space but can't
seem to get it to work.
I am using Ubuntu 8.10 Intrepid
This is what I have done / tried so far.
1. Created a group called delcomusb
$ sudo groupadd -g 1001 delcomusb
2 Created a file in /etc/udev/rules.d called 99-delcomusb.rules and
placed the following. I tried both.
# Delcom USB Device
SUBSYSTEM=="usb_device",
ACTION=="add",
ATTRS{idVendor}=="0x0FC5",
ATTRS{idProduct}=="0xB080",
GROUP="delcomusb",
MODE="0660"
#BUS=="usb", SYSFS{idVendor}=="0x0fC5",
SYSFS{idProduct}=="0xB080", MODE="0666"
3. Restarted udev
$ sudo /etc/init.d/udev restart
4. Added user to have access to group: delcomusb
System -> Administartor -> Users and Groups
unlock user (and then entered password)
select user ed
click on "Manage Groups"
click on delcomusb
check ed and root for Group Member
But still get the error when I try and run
./DelcomUSBDevice.py
self.handle.claimInterface(self.intf) # Interface 0
usb.USBError: could not claim interface 0: Operation not permitted
But everything works fine with sudo.
Is there some step I missed?
Thanks
ed
