I use Windows 8, and ADB seems to not be able to find my LG Nexus 5 (D821) despite having installed LG Universal Mobile Drivers (LGUnitedMobileDriver_S498MA22_WHQL_ML_Ver_2.2).
adb reboot bootloader failed to find the device.
I have set the device in USB debugging mode. It does not seem that LG provides anymore anything else than the manuals on their new website.
Which USB driver should be installed to detect LG Nexus 5, and where can I download it?
