Re: Does Raspberry Pi 3 B+ support UASP?

OK, no, the Pi does not support UASP what ever that is. And is unlikely to do so in the future. As for your other stuff, this is what I would recommend. Install Rasbian on the PI, its the most robust of the OS's because its the one we develop the Pi on. Set it up as standard, don't worry about TRIM ...

Re: Defective? Blinks 4 long 7 short

It's not a BGA, it's a QFN. Soldering QFN (or even BGA) is not a problem for me, it's part of my job :) Since I saw the same error when I used a lab supply (I'm fairly positive to have figured out where to apply which voltage), I figure that whatever killed the PMIC in the first place probably took...

Re: Defective? Blinks 4 long 7 short

I've replaced the PMIC since it was broken. Before I did that, I powered all five rails from a lab supply, it behaved exactly the same. I was under the impression that there are no further regulators on the board, right? I'll let you know after the weekend if all voltages are as expected, I didn't ...

Re: Defective? Blinks 4 long 7 short

4 long 7 short is a power failure message.

Not sure what exact circumstance can bring up that error, but I suspect the PMIC is dead.

Try taking out the print statement at the end, prints can take a load of time.

Failing that, rewrite in C for more speed.

Re: Turning off and on individual USB ports on the Raspberry Pi 3?

It's a cheap USB fan I bought at a CVS years ago, would it just be possible to cut the cord and splice it to the GPIO pins? I believe they output a straight 5V making the connection easy. Depends on the current requirements of the fan, too much will overload the GPIO's. Oh, and the GPIO's are 3v3..

Re: Turning off and on individual USB ports on the Raspberry Pi 3?

Not from the USB, but you could do it from the GPIOs which is what most fan people do AIUI.

Or get a POE HAT with the built in fan, but cheapr to roll you own fan solution.

Or perhaps a simple heatsink will do the job?
