xhc-hb04 homing problem

I recently posted this question but probably did not explain myself well.. I used to run axis through a parallel port on Linux wheezy, I had hard drive issues and rebuilt the software but this time I used Linux Buster and a Mesa card (all working well) now my originally working xhc-hb04 pendant home-all button fails with an error message 'not in joint mode' (or something similar - I'm in my study at night at the moment), all other buttons that were originally working are still working, just not the home-all button, so I don't see where the problem is as the wheel will move each joint, the origin button moves the joints to origin etc.
Can someone assist? or point me to some documentation.
I'm using Linux debian 4.19.0-10-amd64 #1 SMP Debian 4.19.132-1 (2020-07-24) x86_64 GNU/Linux and my hal, ini and pendant hal files are attached.
any help appreciated
Eric

uname -a gives me... Linux linuxcnc 4.19.0-10-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.132-1 (2020-07-24) x86_64 GNU/Linux
but that is none of what you mentioned, perhaps I am using an unsuitable version? homing with the button works when I first turn on, but I normally use the home all button in axis, when a program completes I can use the home all button again (with the usual message saying it is already homed) but the pendant home all no longer works,
How do I unhome all in axis?
I tried the $ shortcut but that also does not seem to work
Tomorrow I was going to try going back to Debian 9 (stretch) with an earlier version of LCNC to see what happens
thanks

Thanks for the feedback, I'm a bit slow at times, I see the version every time I start LCNC up but it never registered, Anyway, I'm using 2.9.0 -pre0, also I used unhome-all from gui menu (never used that before) and the pendant button worked, the $ key seems to have no effect.
Does this suggest I should use a preconfigured LCNC with 2.8.x ?

That shortcut appears to not exist any more in 2.8+
since the Joints-Axes changes.

In 2.8 and up, the axis gui '$' key binding is available
for non-identity kinematics.

If using trivkins, one can use the module parameter
'kinstype' to force non-identity kinematics

many thanks andypugh, that did fix it, I must try and learn more of LCNC, i do find it a bit overwhelming though not being much of a programmer.
And thanks dgarrett I'll read what you posted.

ps. there seems to be a need for an idiots guide to LCNC, I don't understand half the terminology such as kinematics which I had to look up and still don't quite understand and trivkins etc
