[Hackrf-dev] HackRF not working at all

[Philipp Hug]

Hi,

I recently received my HackRF but it seems there's something broken with it.
When I connect it to a USB3 port on my linux machine, I can see the
following in the kernel logs:
[18047.459099] usb 1-2: new full-speed USB device number 5 using xhci_hcd
[18047.571290] usb 1-2: device descriptor read/64, error -71

---
on another machine with an USB2 port nothing happens at all.

On the hackrf no lights go on and exactly the same happens when I
press DFU while connecting to the computer.

Do you have any ideas? Looks like a hardware defect, right?
