Prior to windows 10, for a usb device, you supply an.inf file to install the driver. We have an.inf file for our device that installs and uses usbser.sys and is necessary for specific information in the inf file to identify our device. However, when using our inf file to install in windows 10, after it's installed, it shows in the device manager under ports with the warning indicator on the icon and a code 10. Then, when we plug our device in, it uses the built-in windows 10 usbser. Hp Laserjet 1012 Windows 10 Driver. inf file and it shows our device as connected under ports as 'USB Serial Device'. We need our string to appear there. A) how can I find out why it gets code 10 for our inf install (is there other information that needs to be in the inf for windows 10 that wasn't needed in all other windows versions?) and b) how can we override the windows 10 built-in usbser.inf file for our inf file, or is that the way it will work when the code 10 is taken care of? Hi, thanks for the reply.
Windows 10 Driver Support Has Stopped Working on this page. I had actually seen those pages in my searches and wasn't able to make headway. On win8/7, after installing our inf file, the item appears in the Device Manager ports section (show hidden devices) and when a device isn't connected, its status is 'Currently, this hardware device is not connected to the computer. Once you plug in the device via usb, it of course changes to 'This device is working properly.' More info.still not solved, does anyone have any insight into this? Our device has a class code of 2 and subclass code of 0. According to: msdn.microsoft.com/en-us/library/windows/hardware/dn707976(v=vs.85).aspx then the following applies: •If you want to load Usbser.sys automatically, set the class code to 02 and subclass code to 02 in the Device Descriptor.
