NOTE: You, the customer, are solely responsible for data security. WinBook strongly recommends that you perform a backup of all personal data contained on your system prior to performing this procedure. Warning: WinBook will NOT be held responsible for any data loss incurred during this process.

Note: Green question marks can occur with the following USB device classes: Keyboards, mice, and Universal Serial Bus (USB) hubs. USB printers usually do not directly exhibit this issue, and thus are not affected by green question marks. This indicates that an exact (device-specific) driver is not available, and that a compatible driver has been installed. This new feature was implemented so that you can use the device, even if an exact driver is not available. Even if a device contains a green question mark, most if not all of the features will function properly.

Use the following procedure to try removing the green question marks:

1. Disconnect any extra USB peripherals connected to the computer, such as a scanner or printer.
2. From the Start menu, point to Settings, and then click Control Panel.
3. In Control Panel, double-click the System icon.
4. In the System Properties dialog box, click the Device Manager tab at the top of the window.
5. In the Device Manager window, double-click Universal Serial Bus controllers.
6. Listed under Universal Serial Bus controllers, locate and write down the name of the device with the green question mark beside it; this is commonly the Generic USB Hub.
7. Click to select the device that has the green question mark beside it, and then click Properties.
8. In the Properties dialog box, click the Driver tab at the top of the window, and then click Update Driver.
9. In the Update Device Driver Wizard dialog box, click Specify the location of the driver (Advanced), and then click Next.
10. In the Update Device Driver Wizard dialog box, click Display a list of all drivers in a specific location so you can select the driver you want, and then click Next.
11. In the Update Device Driver Wizard dialog box, verify that Show compatible hardware is selected. In the Models section, click to select the device name that was written down above, and then click Next.
12. If an Update Driver Warning dialog box appears, click Yes.
13. In the Update Device Driver Wizard dialog box, click Next, and then click Finish.
14. When complete, in the Properties dialog box, click Close.
15. Verify that the device no longer contains a green question mark. Follow this process for each device containing a green question mark.

Note: If a device other than one provided by WinBook contains a green question mark, please contact the vendor of the device. A new or different driver may need to be installed.

Note: If the above procedure does not successfully remove the green question marks, Windows may need to be reinstalled.
