Do you have libimobiledevice tools installed? If so, could you run idevice_id and ideviceinfo and paste the results? If you don't have them, you can download the tools from here

The "Unknown Device" is a quirk with iloader error handling, I will look into better ways to handle this case. The real problem however seems to be that usbmuxd is detecting your device but hangs when actually trying to connect. Try what jkcoxson said to see if that works

I was having this same issue on NixOS and can confirm that installing the libimobiledevice tools fixed it for me. Thanks!

used original libimobiledevice:

$ ideviceinfo
ERROR: Could not connect to lockdownd: Mux error (-8)
$ idevice_id
00008120-000A2D8C14E0201E (USB)

used idevice by jkcoxson: (i ****** my Download folder for it ;-;)

$ ./Downloads/idevice_id
[
    UsbmuxdDevice {
        connection_type: Usb,
        udid: "00008120-000A2D8C14E0201E",
        device_id: 1,
    },
]

$ ./Downloads/ideviceinfo
**nothing**

$ ideviceinfo
ERROR: Could not connect to lockdownd: Mux error (-8)

This is the real problem. Did you click trust and enter your passcode on your phone when you connected it to your computer?
