Mini Brain 2 - No Connected and powered unit found
I recently purchased a mini brain 2 (MSH51635) and have been unable to perform the very first step setup using USB with my PC.
I have installed the software and drivers and when I connect the unit, it makes an audible connection and shows a USB Serial Converter in my USB controllers in device manager. However when I then start the software I am faced with the window "No Connected and powered unit found". I have tried uninstalling and re-installing the software and drivers.
The unit's LEDs flash red and green initially for about 10 seconds when the USB is connected. Then it switches off for a second and turns into a slow flashing red led.
Since I've been unable to connect I tried the recovery process which did seem to get the unit into boot loader mode (steady red LED), but once again when I connect and start the software it shows the same error message.
Please can you advise what I should try to fix this?
Each of us already has at home several of these USB cables provided with all the phones purchased over the years, all the cameras, webcams and with most of the electronic devices of the last decades.
You should therefore already have at least one or more such cables in your home.
Just beware that with some cheap phones, some manufacturers to save on the cost of copper provide cables for charging only but without data connections.
From what you've written it sounds like you're using one of these cables that powers the flight control unit but doesn't have internally the communication cables.
We therefore suggest you try another cable.
@customercare thanks for your response. I'm using the cable that came with my Raspberry Pi, which must contain the data cable. I've already tried a number of USB cables all with the same results. I also have a cable I know doesn't contain the data wire and can see that this particular cable does power the unit but nothing then appears in device manager, so I think I know what to expect when using the wrong cable.
I would say from this diagnosis that I'm using the right cable. I've also tried on two different computers, so we can rule that out.
Any other suggestions?
You have already tried uninstalling and reinstalling the Windows app,
You have already tried on two different PCs,
You have already tried various other USB cables,
If you have already checked that both connectors of the cable that connects the remote USB to the SYS port of the FCU are both well inserted to the bottom and that no pin of the two connectors has been bent during the insertion and that the cable has not shorted against an edge of the model carbon frames,
If you've been waiting for Windows to recognize the connected product and install the drivers (downloaded but not installed by Windows until the product is connected to the PC), there's not much else you can do.
Therefore, if the product is new and still under warranty ask for a free replacement under warranty at the store (physical or online) from which you purchased the product (it would probably be enough to replace only the remote USB or even just the cable connecting the remote USB to the FCU SYS port).
