Yes, Pi400 remains a problem. (I have one)
But the Pi400 _probably_ isn't a good CNC controller candidate?

Today test with brand new pi 400 using :
www.linuxcnc.org/temp/image_2021-01-20-linuxcnc-pi4-3G.zip.

The LinuxCNC docs now point at a (renamed) version of the 3G limited image, with warnings that it is known to not work on all variants.

andypugh, according to my latest test (see my previous post), the www.linuxcnc.org/temp/image_2021-01-20-linuxcnc-pi4-3G.zip does work on Pi 8GB. Wlan and USB are ok.

There might be a fix in the kernel discussed here:
github.com/kdoren/linux/discussions/3#discussioncomment-389373
There is a downloadable kernel image deb here:
github.com/kdoren/linux/releases/tag/5.10.16-rt30
(I have not tried it)

EDIT: Apologies for the redundant post, the 2.8.1 image works for me. linuxcnc.org/downloads/ still only shows 2.8.0 which is where the confusion occured. I found the 2.8.1 image in the end at linuxcnc.org/docs/2.8/html/getting-start...tml#_normal_download
Hi I'm having the same issue (no mouse, no keyboard) with the raspberry pi 4b 4Gb model.
I'm able to ssh in to the pi, here is the output for uname -a:Here is also the output of lsmod just incase it helps:I'm happy to help you get any more information

the image at
www.linuxcnc.org/temp/image_2021-01-20-linuxcnc-pi4-3G.zip
is a 404 not found
and the image
www.linuxcnc.org/iso/linuxcnc-2.8.1-pi4.zip
does 'work'
it gets you an image that has usb and wifi
but has memory limited to 3078 in config-rt.txt.
so
there is no fix for the usb wifi memory problem
there is a work-around for the usb and wifi problem,
and that 'fix' requires limiting memory on 4 and 8 gig Pi's,
I followed both threads end to end hoping for better..
But, better does not exist yet ( 15apr2021 )

Thanks, I will try your newest 64 bit image
