Is there any "universal" vendor ID that I can use so that ADB can detect my China-made Tablet? I can't find the vendor ID of the manufacturer. When I look into Device Manager in Windows the Vendor is a string and not a number. The device is a Cherry Mobile Fusion Bolt tablet.
Try this tool if you are on a windows machine- lsusb Link
If you are on a linux machine, you can run the lsusb command.
The tool is for windows platform. Run it while your tablet is connected through a USB. It may show your Vendor ID. If it does, you can try manually adding it to [USER_DIRECTORY] / .android / adb_usb.ini.
