问题
I built a new Windows CE image and placed two USB drivers. One for the USB printer and the second for some special device with digital and analog I/O ports.
I have one problem that came out with the drivers while the operating system boots up.
Every time the image boots up it asks to enter the driver's name. (The message is "Unidentified USB Device" Enter the name of the USB device driver) Is there a workaround for this problem ? What does I have to put into a registry?
I did not check if the driver is working after that because of my second problem with the SQL CE 3.5 in my application.
The similar problem is happening if I not add a driver for example the Audio subsystem. The OS at boot up scans the devices and finds some new hardware asking to fill the name for the driver.
It is simple to correct the second situation. I only have to check the item in the catalog view and rebuild the image. On behind the ragistry is filled with correct parameters but what am I supposed to do with custom drivers ?
回答1:
The "Unidentified Device" dialog happens when the USB node is queried and no macthing driver in the OS is found. Which device, specifically, is causing that? You mention both a printer and an I/O device - knowing which device is causing the error will help narrow it down.
When you "added the drivers" to the OS, did you just add the driver binaries, or did you also add the relevant registry entries in the drivers section? Those entries depend on the specific driver, so I can't tell you exactly which keys and values you need.
