Hi welcome to the forum.
There are two types of usb device.
A host controller (normally a PC) and a device controller (normally a USB mass storage device like a flash memory stick or a USB hard disc drive).
A host device has to connect to a device controller – host to host and device to device won’t work.
The Foxsat-hdr is a host controller so needs to connect to a mass storage device.
There is third party software that lets your laptop access the hdr’s HDD directly over a home network.
