If so, its not going to be broken by a software update any time soon, tinfoil hats not withstanding.Earlier models of the Dot used a garden variety micro USB port for power, which hackers eventually figured out also provided a helpful way to snoop around inside the devices firmware.The fact that the USB port was deleted on the latest Echo Dot in favor of a simple barrel connector for power was seen by some as a sign that Amazon was trying to keep curious owners out of their hardware.While they removed the external USB connector, the traces for it are still on the board waiting to be accessed.

All you need is a simple breakout that will connect through the existing opening in the devices case, and youve got your USB port back. Brian found that the Dot shows up as a Mediatek device under Linux using lsusb, and fastboot can see it and even confirms the presence of a locked bootloader. Its going to take some work from the community to see how deep this particular rabbit hole goes. Hes mapped out many of the test points located throughout the devices PCBs, and found a few interesting points that might be worth further investigation. For example, he found that driving one of the pins high would trigger the Dot to mute its microphones; which could be useful for anyone looking to cover Alexas ears. It looks like hes making fairly rapid progress on unraveling the mysteries of this popular gadget, and were very interested in seeing where this research takes us. Man, i hate that connector even more than the old scart video connector. This is the same reason USB type A and Mini-B ports can wear out in ways that require a device replacementrepair the springs are on the device side of the interface. Just look at the boondoggle of a USB-C implementation on the PI4. Is it just normal 5v usb power 20v USB PD power does the device support 20v or is it going to fry when its circuitry that expects 5v encounters 20v. ![]() Grabbed the first to hand (was in a hurry) and got a perfectly rectangular smoke ring from between the case halves of the handheld. Even my amateur circuit boards have considerations for that. ![]() I bought a four-pack of 6.5 Volutz micro-USB cables well over a year ago and I have had zero problems with them, where cheap cables would do well to last a couple of months. Come to think about it, this is the first Ive heard anyone mention of a USB cable wearing out. Sorry, i dont know Amazons business model: Do you BUY these ears or do you RENT them If you BUY them it is YOUR hardware and you should be allowed to do anything you want with it Yes i know, laws not always work this way, but they really should. But that doesnt mean they have to make it easy for you (as much as I wish they would). Is that just a link to a GPIO on the Dots CPU Then its software that causes it to mute the mics when it sees its high. Maybe other physical phenomenas too like miniscule oscillations in CPUs voltage regulator this can be sensed and decoded although voice quality is abysmal.
