Try running the driver installer from within PE, see if that works..
sometimes drivers pre request other drivers operational...... on your case maybe gpu driver ! maybe something else..... let us know if you figure out.
While in PE after cam driver installed - close reboot request - try HwPNP - Install Drivers (HwPnp) shortcuthave to add HwPnP plugin and create shortcuts
Often cam is connected with internal usb. Look into native Windows with devicemanager. Switch to view by connection. Follow the complete chain from chipset(apic)-system, over pci-bus, usb-controller to cam. You need for all devices of this chain the drivers. In HwPnp the option +a (or +all). Eventually a "+hardwareID" from one of the chained devices, for example, a shortened ID of cam. Example:Code: [Select]My cam hardwareID: USB\VID_05C8&PID_030E&MI_00 (<--if you gogle with this hardwareID: "FH13FF-238" and "FUJITSU")In HWpnp Plugin => +USB\VID_05C8&PID_030E Besides Windows system needs additional dll('s) - to build dataconnection to cam. And for resizing of image frames. Maybe DirectShow filter(s).If for successful cam operation DirectShow filters are needed on your PC - the free-for-private-use program 'filmerit' would help you. The several drivers can be extracted with DD - structured folders.If you figured out, whitch filter is missing in your PESE and you haven't any idea how to add this - I will help you with Registry export and dll name(s).
New topic: Add USB Video Class Driver to PE x64 (usbvideo is not a driver for a physical device)Checked: USB Video Class Driver is included in Win 10 Pro source-DVD. (should be in Win 8.1 too)Web-Link: USB Video Class Driver Overview@JustinEPls go with explorer to extracted install-WIM-folder of your 8.1 source-DVD;Usually: .\sources\install_wim\Do a search with expression 'usbvideo.sys' on \install_wim\;You may get 2 usbvideo.sys.mui- and 2 usbvideo.sys search results.Now I ask you for the name of your folder in .\Windows\System32\DriverStore\FileRepository\, whitch contains the usbvideo.sys( For me this means folder: usbvideo.inf_amd64_fe8d886bc5539514 )
