How To Install Qualcomm USB Driver

On All Windows systems (XP/Vista/7/8)

  • 64-bit systems must have test certificate installed first. See section below “On 64-bit Windows systems” before attempting to install.
  • Manual Installation: follow the procedure documented in 80-V4609-1, point the driver to the fre/chk path (e.g. QMI\win\build\target\fre\Win7) when system asks for driver files.
