Undefined reference to usb16Crcdappend

[cipherswami]

I manually added, library to ArduinoDriod and compiled the .ino file which includes DigiKeyboard.h library, then I'm getting this error.

Note: complied from Android device.

Check bootloader while uploading code to Digispark and also port.
If bootloader is missing then, the code cannot run and not uploaded into Digispark.

Thank You
