libpci was only used to find a marketing string for a device. This patch looks for a pci.ids on disk and parses it to extract the same string, using 'Device xxxx' as the fallback on file i/o error or missing data from the text file. Tested by checking every vendor/ device pair against the values returned from libpci.
