The following is a list of machines known to have been tested and work without issues on EmbroideryConnect. Even though your machine is not listed it does not mean it is not supported.
Generally if the embroidery machine has an native USB port it will support the EC device, however some older embroidery machines may use different USB standards that require a hub or special configuration.
If you want to inform Wilcom of a machine model that is not listed please submit a support ticket
