Consider the following scenario: There are multiple instances of same type device attached to your computer. For example, there are two devices with Device Instance Path like:
Device 1: PCI\VEN_XXXX&DEV_YYYY&SUBSYS_00000000&REV_ZZ\1&01;
Device 2: PCI\VEN_XXXX&DEV_YYYY&SUBSYS_00000000&REV_ZZ\1&02;
They have the same hardware IDs (PCI\VEN_XXXX&DEV_YYYY&SUBSYS_00000000&REV_ZZ). You may encounter the following driver installation issue:
1. When there is no inbox driver available for this type device, you may use Device Manager to launch "Update Driver Software…" wizard from the menu "Action ->Update Driver Software" when you select Device 1, and provide the location of vendor's driver if Windows can't find the driver automatically. Finally, you installed driver successfully to the Device 1. However, the Device 2 may still has no driver installed after Device 1 had been installed, you have to select Device 2 from Device Manager to launch "Update Driver Software…" again to install driver for Device 2 even these two device share a same device driver;
2. When you are updating the driver for both device 1 and device 2, if you still use Device Manager to launch "Update Driver Software…" wizard when you select Device 1, and provide the location of vendor's new version driver by selecting "Browse my computer for driver software", finally you updated driver successfully for Device 1. However, the driver for Device 2 may still use old version driver or Device 2 also has a new version driver but doesn't work as expected;
Device Manger performs driver installation or update as a device-centric fashion. Device Manager only updates the driver to the selected device. In scenario 2 described above, driver binary file of Device 2 may be replaced by a new version file, but the device settings of Device 2 is not updated, the driver may see unintended setting.Note: Software-First driver installation and Windows Driver Update don't have this issue.
1. Launch "Update Driver Software…" wizard for each device thatyou want to install or update the driver for.
2. Use the driver installation application from device vendor or Windows Driver Update if possible.
