Again, I have a strong feeling that RPI4 with a connected USB SSD is the issue - maybe drawing too much power and frying in the process.
Nope. My Pi 4B2 running a Minecraft SMP server 24/7 has its OS on a USB 3.0 SSD (SATA-III SSD with a USB 3.0 adapter cable).

Re: The mystery of 3 dead pi4s

If you've had THREE computers die in less than 24 hours (each) then something you are doing is killing them. We need to know everything about your setup (hardware and software) to help find the cause. FYI: I've had a couple of Pi 4B computers for awhile now with no trouble at all, and one runs a gam...

Re: Pi4 boot from USB via SD boot folder

@RonR: yes. my UIDs are the same, as I etched the USB SSD, and copied /boot to the SSD. That's a confusing statement. You should have used Etcher to write the image to the SSD, and then copied the files on the SSD "boot" partition to a FAT32 formatted card. If you somehow cloned the /boot partition...

Re: Should you buy an A2 performance rated SD card?

Got tremendous performance gain using A2 sd card, (so I disagree with OP). You need to test against an A1 app performance rated card, not a standard Class-10 card. A2 cards are faster than standard cards (and I said so above), but A1 cards are faster and cheaper on Pi computers (and most other devi...

I came across this post randomly and figured I'd correct it. Your "correction" is flawed. The problem with the OP had nothing to do with OTG. The OP was trying to connect a keyboard to the micro USB power port, which has no data lines. So the previous reply was correct and no correction was needed.
