Re: WIFI adapter in USB hub won't work with latest Pi OS

Thanks for that. Weird thing is, I have been using it for over a year now, plug + play without having to do anything extra? It works right out of the box in Stretch or Jessie. If that driver will get it working I'll happily install it though.

Re: Raspberry Pi 4 White/Red Case Sufficient

I also really like that case, from a looks perspective. It's a nice quality case. But, unless something has changed, IMHO, it's lacking in ventilation. There are no vent holes to let hot air out. The Pi 4 will not overheat, but if it does get overly hot it will throttle back to keep from overheating...

Re: No red LED Pi 4B

I would think that if the voltage was so low that the LED didn't turn on, that the Pi wouldn't even boot up? Maybe the LED got flipped around backwards some how, and its reverse biased? The red LED turns off when the voltage falls below 4.63V, IIRC. This is well outside the specified minimum of 4.7...

Maybe one of the ground pins needed by the sense hat isn't making a good connection? They are all one commo...

Re: Raspberry Pi shows a colorful screen when booting raspberry pi os desktop

As mentioned, that's normal to see that screen flash up on boot up.
You can disable that if you don't want to see it.
You just edit the config.txt file

sudo nano /boot/config.txt

and add
