In device manager I cannot show any port other than the USB COM4 that the USB is plugged in to. Have also connect via printer cable to a desktop but still nothing. I have tried connecting to 2 laptops, 1 with Vista and one with Windows 10. I have downloaded the drivers from US Cutter site but still will not recognize the cutter. The cutter came with Inkscape and I believe SignCut 2. I FINALLY got the cutter to work in the free SignBlazer I downloaded but it is a trial version so I figure it will run out shortly because I cannot get a code for it. Even after I sent them a pic of the shipping address from the box. Now I am trying to use it but cannot get any help from customer support because they CLAIM they cannot find my info in their computer. So, my mistake was not using the cutter when I first received it. He is the one listed on the return address on my cutter that is in a US Cutter box. A BBB search shows that US Cutter also uses the Selltopia name and lists the US Cutter owner as Marcus Oesterwinter. US Cutter claims they have never uses this name and therefore REFUSES to help me unless I buy new software from them. I bought a MH 721 a few years ago on an ebay auction by Selltopia.
I have searched the forum and customer support for answers but nothing works.
