Code review comment for lp:~adeuring/launchpad/hwdb-class-udev-device-4

This branch adds the properties pci_ids, raw_bus, vendor, vendor_id, product, product_id to class UdevDevice.

The HWDB client in Karmic will no longer send data gathered from HAL, but gathered from udev, supplemented by sysfs and DMI data.

The HWDB submission processing script represents devices found in the submission data in a class derived from BaseDevice; this branch is another step to complete the implementation of class UdevDevice.

I forgot in earlier branches to specify the DMI data as a parameter of the UdevDevice constructor, so this branch contains also a number of purely formal changes in the tests, where class UdevDevice is instantiated.

I also noticed that I forgot a "raise NotImplemented" for a property of class BaseDevice.
