LimeSDR only works with external power

I had a look, tried it on two laptops - but the thing is, there’s no Westbridge device in Device Manager either… Also when I try looking at the " No device found problem, Westbridge device" post and follow the steps to upload the firmware - that doesn’t help, as LimeSuite doesn’t see this board at all in the list after clicking “Options,” then “Connection Settings,” (not even as a Westbridge…).

It’s like the system doesn’t recognize any device at all when I connect my Lime via USB… There’s absolutely no reaction from Windows / Device Manager when I plug in my LimeSDR (but whenever I try a different USB device like an AirSpy in the same USB port, there is the familiar Windows sound and it appears in Device Manager).
