Hi,

Is it possible that the iPhone doesn't natively transmit the screen via USB, and that's what you're trying to do?

Thanks

Hi,

I hope everything is going well?

I just wanted to know if you're still having the problem?

I'd like to share it so we can check the situation.

Thanks

Windows identifies USB devices based on their USB descriptors (vendor ID, product ID, and related fields). If the USB casting/“live screen over USB” tool cannot see the iOS device, Windows is either:

Not enumerating the device correctly over USB, or
Enumerating it, but the software that expects a specific USB interface/driver cannot bind to it.

Key points from how Windows handles USB devices:

Every USB device exposes a device descriptor that contains idVendor, idProduct, and bcdDevice. Windows uses these to build the Hardware ID and Compatible ID (for example, USB\VID_045E&PID_F001).
These IDs are visible in Device Manager → [your device] → Properties → Details → Hardware Ids.
If enumeration fails, Windows may show an Unknown device with USB\VID_0000&PID_0000 and USB\UNKNOWN, often with Code 43 in Device Manager.
If enumeration succeeds but Windows cannot find a matching driver INF, the device can appear as unknown with Code 28.

To troubleshoot on Windows:

Open Device Manager while the iOS device is connected via USB.
Check under Universal Serial Bus controllers, Portable Devices, and any Unknown device entries.
For any suspicious/unknown entry:
- Open Properties → Details → Property = Hardware Ids.
- Confirm that a valid USB\VID_xxxx&PID_yyyy is present.
If the device shows as USB\VID_0000&PID_0000 or USB\UNKNOWN, Windows is failing to enumerate it correctly. In that case, the USB casting software will not be able to detect it.
If a valid VID/PID is present but the casting software still does not detect the device, the issue is likely with the software’s driver or its expectations about the USB interface, not with basic Windows USB detection.

If the device is completely missing from Device Manager when plugged in, the problem is at the physical/USB layer (cable, port, hub) or with the device’s USB stack; Windows cannot provide a USB descriptor or Hardware ID in that case, and no USB-based casting will work.
