| 1487076 | 2022-07-14 03:59:00 | I'll relate as I remember it, bearing in mind it was three weeks ago. The radio was powered up & the USB cable connected to it. When I connected the other end to the PC, it instantly started a reboot. I disconnected the cable before it completed. I then noticed there was no network/internet. At this point I didn't realize the system was damaged & attempted to get the network going again. I wasn't winning there, so decided to carry on without the it. I then connected the radio using the cable that came with the radio. These cables are just standard USB to USB mini B. The USB3 & DVI-D were still working until the second reboot. The radio was powered by it's own NZ AC adaptor There was no antenna connected to the radio. |

Even with a horribly miswired USB cable/port, it should only either damage the USB controller or blow/trip a fuse (they used to have polyfuses on USB ports, not sure if they still do), or more likely, just cause a detection error. The only thing I can think of is a faulty power supply for the radio. Or perhaps a severely faulty USB transceiver circuit in the radio that was outputting the power supply voltage (12v, 24v whatever it is). Again though, I'd expect that to only blow the USB controller. It's very strange. Reminds me of "Bad USB" concept. hackaday.com The effects are similar to what you described. That's why I'd suspect a faulty power supply with bad isolation from the mains because I can't see a high voltage coming from anywhere else. |

| 1487078 | 2022-07-14 22:10:00 | It could be the USB cable the radio came with being incorrectly wired . Ive had that on a USB charging cable , reverse polarity so it blew the device when you first charged it via USB Also, might be a weird earth issue. Where the radio earth & the PC earth had a voltage difference . Ive seen that once on a printer & it blew the PC printer port . Or the actual USB port can sometime be physically broken , so the USB port pins short out |

| 1487082 | 2022-07-21 08:22:00 | Refund received, case closed. No mention of it blowing their computers up as well? |

| 1487083 | 2022-07-21 09:47:00 | No reference at all, just full refund approved. I hadn't actually asked for a refund. For the reason for return, I had ticked faulty item. |

| 1487084 | 2022-07-21 23:50:00 | Ha, it probably blew theirs up as well so they just immediately gave a full refund and hoping to avoid you trying to claim damages from them or something. | Agent_24 (57) | ||
