Sometimes your machine will not recognise the USB stick you want to use for transferring an embroidery design or an update.

Often the USB stick will be too big in capacity for the machine to read (we recommend no more than 2GB, 256MB for older machines)) or has not been formatted correctly.

The easiest way to ensure a working USB is to purchase a Bernina USB Stick that is prepared and checked for compatibility.

Other reasons may be:

Your design has not been unzipped or is in a format that the machine does not recognise. Check your manual for preferred formats.

If you are updating the machine the USB must be formatted correctly (FAT32), empty of any other files other than the update which needs to be unzipped before putting on the USB.
