Q: I bought one Acer 1810TZ laptop, recently after I reinstalled system, I found there’s one USB device could not be recognized. There’s one interrogation mark in device manager. I use GHOST operation system, how can solve this problem?
A: if the judgment is not wrong, then this USB device should be the camera of the laptop. What you need to pay attention to is that although the camera uses internal design, in device manager, it would still display as USB device. Laptop users usually would pay attention to USB interface, and then this probably would cause confusion. In fact, it’s not difficult to install camera driver. First of all, enter device manager; check the property of USB device, later then you can check the camera hardware ID. At last, just compare according to the table provided on Acer official website, then you can ensure the detail model of the camera, download and install the driver, then it’s done!
