Description Christian Tacke 2013-10-03 16:01:43 EDT
Description of problem:
I have a FTDI cable with FT232 chip inside. I could not access this device with libftdi as a user (I'm in plugdev group). Also ls -l /dev/bus/usb/xxx/xxx shows that only root can access the device

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.plugin device
2.get bus and device number from lsusb
3.check ls -l /dev/bus/usb/xxx/xxx for plugdev group

Actual results:
ls -l /dev/bus/usb/xxx/xxx shows root root

Expected results:
ls -l /dev/bus/usb/xxx/xxx shows root plugdev

Additional info:
/etc/udev/rules.d/99-libftdi.rules doesn't include idProduct for ft232 device which is 6001. Solution: adding to the rules the line: SUBSYSTEM=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", MODE="0664", GROUP="plugdev"

libftdi sources contain this and other lines.
