Do these devices appear if you use the node-usb library directly?

[yene]

Yes, it is reported by node-usb usb.getDeviceList()

When I connect the GPS Receiver to the other USB bus (a different USB port) he appears in webusb.
It seems the second USB bus is filtered out somewhere in the code. I did a quick look but found no location where this could have happened.

That is strange. As a test, you can "fool" webusb into listing all devices returned by the libusb adapter by passing an invalid filter:

usb.requestDevice({
    filters: [{something: null}]
})
.then(device => {
    ...
});

This will at least tell us if its the filters removing your device if it correctly appears in that list.
