Comment 4 for bug 1334991

in removable_storage_test

269 if (pci_slot_name ==
270 udev_device.get_property('DEVPATH').split('/')[3]):

for unknown reasons, the DEVPATH pci slot looks like, for example from the comment #1

E: DEVPATH=/devices/pci0000:00/0000:00:1c.6/0000:08:00.0
......
E: DEVPATH=/devices/pci0000:00/0000:00:1c.6/0000:08:00.0/usb4/4-4/4-4:1.0/host19/target19:0:0/19:0:0:0/block/sdb

namely, the parser should be sth. like
   udev_device.get_property('DEVPATH').split('/')[4]

to get the right pci slot to compare.

----

NEXT:
figure out how the hierarchy was decided and
how to integrate the parsers, split('/')[3] and split('/')[4].

namely a smarter parser should be provided.
