Re: Why USB-C ?

The TVS diode remains in circuit, but there is no polyfuse on the Pi4B. So if you must (IMO, foolishly) use a barrel jack, you should wire an external polyfuse between the socket and the Pi. Then you will have some protection for when you plug in a PSU with the wrong voltage or polarity. Ah, I susp...

Re: Why USB-C ?

If you really really really want to power your Pi using a barrel jack, wire one in to the +5v and GND on your GPIO. You will lose overvoltage protection though I think.

Re: Pi wifi re/connection

If its any help, I have had similar wifi issues in the past where reconnection fails. I tried running a script to ping my router at regular intervals but the pi's got a ping back ok but SSH failed, so gaining control back was not possible. My solution now is to have a wired Pi running a simple webse...

Raspbian Buster editing file over network corrupts file contents?

I've noticed an apparent bug(?) with Buster, when I select a file through File Manager on another computer (Pi) on my network it allows me to edit the file and save it, but when I try to re-open the file later I find that the contents are corrupted, either garbage characters or the contents are only...

Hi I've been searching for a way to redirect serial input (for example /dev/ttyUSB0) to the terminal console, so anything coming FROM an external device gets echoed to the screen, as if it is being typed. Is this possible? All I can seem to find is how to redirect stuff TO the serial port... thanks ...

Yes I have several wireless Rapoo mouse and keyboards, I have had same problem with mouse freezing. As Andyroo said, put the USB adapter on an extension cable and place it closer to your mouse.

Re: Mouse Issues

Try plugging the mouse usb adapter into a usb extension lead, and placing the adapter closer to your mouse (and away from the pi)

I've had similar issues with wireless mice on a Pi 4 - this has fixed it. it seems to be interference off the usb 3.0 ports

I think I have fixed the problem.

It seems that the problem is interference from the PI4. Looking at other forum posts, it ma...

Not related to your usage, but I'm seeing mouse freezes using 2 different wireless mice on raspbian buster / pi 4.

VerY annoying and only unplugging the usb dongle unfreezes the mouse. These units work fine on jessie/stretch/pi2s/pi3s

Re: PI 4 - can't change desktop resolution VGA

Just to clarify, setting via EDID doesnt work with this VGA adaptor as it doesnt return any information to the pi.

Tvservice -n is blank

Xrandr works perfectly if you know the output modes of the monitor
