Hardware certification device information

Mon Aug 31 02:28:12 UTC 2009

Hi again folks,

I'm already done with most of the implementation which should be in
production this week barring any unforeseen complications. The result
of my exploration has determined that the following information will
prove to be sufficient for uniquely identifying and representing the
devices in a system:

    path: sysfs path used to determine the hierarchy of devices
    bus: subsystem name corresponding to the subsystem symlink
    category: initial attempt to categorize devices
    driver: the drivers used by the device
    type: the content of the type file under some devices
    vendor_id: for vendors of pci, usb or pnp devices
    product_id: for products pci, usb or pnp devices
    subvendor_id: subsystem vendor id for pci devices
    subproduct_id: subsystem product id for pci devices
    vendor: for devices with vendors identified by string
    product: for devices with products identified by string

For completeness purposes, I have attached the result from gathering
the above information using Checkbox. Note that if the vendor and
product information are None, this means they will be determined on
the server side by looking at the latest id tables parsed from
reference sites.

There is still one problem I haven't been able to solve: the type
file which is sometimes available for some devices under the sysfs,
is this specific to a device instance or a device model? In other
words, can the content of this file change between systems of the
same model or even between different versions of the kernel?

If you have any other comments, please let me know.
