Public bug reported:
Binary package hint: udev
When I try to get the sysinfo of my ftdi-chip (FT232R) with "udevinfo -a
-p /sys/class/tty/ttyUSB0" I get the following output:
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.

Furthermore the udev-rules regarding the usb-device are not working and
I think this could be due to this bug.
