Many new Macs and Windows PCs feature USB 3.0 ports.
The VRM Box is a USB 1.1 device, and many USB 1.1 devices can have problems with USB 3.0. This is because the USB 3.0 specifications do not require USB 1.1 devices to be compatible.
As such, it is highly recommended that VRM Box users, as well as users with any other USB 1.1 device, do not use USB 3.0 ports.
As always, any questions or concerns can be directed to our support team here.
