pci_test.py error on valid VL805 USB Controller #36

Closed joshschmelzle closed 2 years ago

joshschmelzle commented 2 years ago

Investigate pci_test.py and make it more robust to handle different lspci responses for the VL805 USB Controller.

Error:

E    AssertionError: assert ‘USB controller: VIA Technologies, Inc. VL805 USB 3.0 Host Controller’ in ‘03:00.0 USB controller: VIA Technologies, Inc. VL805/806 xHCI USB 3.0 Controller (rev 01)’

As another data point, when we update (sudo update-pciids) the PCI ID list the description for the VL805 USB controller is changed:

wlanpi@wlanpi:~ $ cat /usr/share/misc/pci.ids | grep VL805
        3483  VL805 USB 3.0 Host Controller
wlanpi@wlanpi:~ $ sudo update-pciids
