I have never had any problem with that model running the LinuxCNC image...

Anyway, I have built a new SD card image, and kicked off the build of a second with the memory limit.
I did plan to put them both on the server for testing, but something has come up here and I am going to be away from my computers for a few days.

I never get problem before, but from some time i get no more usb as you can see after installing kernel on official debian, or after apt-get upgrad with your image.

Maybe this is because i have updated the boot eeprom, i really do not know why but for sure i get usb problem recently with this old model.

Many thanks for the work done, I hope to you nothing bad is happened !

There is a new SD card image here:

www.linuxcnc.org/temp/image_2021-01-20-linuxcnc-pi4-3G.zip

It works for me on an old Pi4 4GB and a new Pi4 2GB. Both as a fresh install and after apt-get update / apt-get upgrade.

I would appreciate it if owners of new 4GB Pi, 8GB Pi and Pi3 could test it and report back.

Running the new image

It works on my Pi4B 4GB. Fresh install and after apt-get update / apt-get upgrade

It works on my Pi4 4GB too. Thank you.

I tried on my Pi4 8Gb, USB works, unfortunately wlan does not work. With the released LinuxCNC 2.8.0 and 2.8.1 images for Pi I had no problems with wlan, but USB did not work. Is there any specific info from logfiles or output from network commands you want me to post here ?

I see the same issue with my Pi400.
At least there is a workaround for Wlan, you can use ethernet or a plug-in WiFi dongle.

With the released LinuxCNC 2.8.0 and 2.8.1 images for Pi I had no problems with wlan, but USB did not work.

How could you tell that WiFi worked without USB to cycle through the setup and type in passwords?

I have the same problem with wlan.

I think I had problems with wlan in December, but I thought it was a bad wifi-router. USB probably worked for me at the time, but not wlan.

I wanted an RPI4 + mesa 7i96 to drive the lathe, but the RPI was so slow, so I didn't use it and used a desktop computer. That's why I wasn't interested in wifi. Then I wanted to find out in January why RPI4 + mesa 7i96 was unusable, but there was a problem with USB that blocked my entire RPI4.

My chromium browser didn't work. I reinstalled it, but it didn't help. That's why I installed firefox-esr
