I tried all the ways listed on the web for a whole day, but I didn’t get any solutions. Then, I followed a link and in just two minutes my problem was solved!
By the way, it’s for Windows users!
Find out the vendor id of the device from device manager.
To do this, connect the OTG port to the USB port of your computer.
Go to Start Menu and right-click on “My Computer” and chose “Properties”.
Select the “Devices” option which will open “Device Manager”.
Select your device (mostly in USB devices or Other devices) and right-click and choose “Properties”.
Choose the “Details” tab and select “Hardware Ids” from the property dropdown, you can see the hardware id, in my case it was x2207 .
Open android_winusb.inf and add these lines:
;<Device name> in our case I gave MK808 %SingleAdbInterface% = USB_INSTALL, USB\VID_2207&PID_0010&MI_01 %CompositeAdbInterface% = USB_INSTALL, USB\VID_2207&PID_0010&REV_0222&MI_01
Open C:\Users\.android\adb_usb.ini and add the following entry
0x<device id> .. in our case it is 0x2207
Restart ADB by
adb kill-server adb start-server
Now ADB should recognize the device.
