ibi9718 years ago000The description says that you can connect the mouse with USB and Bluetooth. Is the USB version wireless or do you have to connect via cable?Show in original language (German)Erytheis8 years ago+110 Helpful answerHello Ibi971, You have a Unifying dongle and a USB cable in the scope of delivery. This means you can connect the mouse wirelessly with the dongle or you connect it to the cable - this also charges the battery. GreetsShow in original language (German)Comment
