I can't get Calibre to read my device on two different machines...

Windows 10 build
64bit and 32 bit versions of Calibre

it reads the device metadata so very slowwwwwww, and then gives this error

Failed to create stream interface to write to object: hr=2147942406 facility=7 error_code=6 description: The handle is invalid.


Traceback (most recent call last):

Windows 8.1 Build is also a 64 bit machine, but I have only tried the 64bit version of Calibre


Any and all help will be much apprecieated...
