I did come across that, group seems ok, am i right:

 sven@svencnc:~$ groups sven
sven : sven dialout cdrom sudo audio video users

I'll look in to permissions for the usb port.

I followed:
www.xmodulo.com/change-usb-device-permission-linux.html

and now have:
crw-rw---- 1 root dialout 188, 0 29 nov 15:20 /dev/ttyUSB0

For good measure I switched wires again for testing.

sudo usermod -a -G dialout $USER

log out, log in

and it's usually a good idea to have rs485 devices grounds connected. it *may* work with just 2 wires, but it's easy to get out of the transceivers common mode voltage range

Thanks, will try tomorrow.

Just to be sure, $USER=$USER or $USER="me" in this case? Or even $USER=$"me"?

$USER is a shell environment variable which will be replaced by the current user name. e.g:

dmitry@nostromo:~$ echo $USER
dmitry
dmitry@nostromo:~$

or you can type your login name instead of $USER

If the tty cannot be opened due to permissions LinuxCNC will not start since the hy_vfd component will fail to start. This is not the case, so permissions on /dev/ttyUSB0 are likely not the culprit.

Please start a terminal, do a 'cd ./linuxcnc/configs/<your configuration>' and start linuxcnc using the command 'linuxcnc <your configuration>.ini'. The terminal will show errors as they occur. Look for something related to hy_vfd
Most likely they are also in linuxcnc_debug.txt or a similar named file (I am not behind a LinuxCNC PC at the moment)

Question to the forum: are there any breaking changes in hy_vfd between LinuxCNC 2.7/Wheezy and LinuxCNC 2.9/Bookworm?

@ Bart:
It looks like the stuff about xhc-hb04.tcl may also relate to the high acceleration during homing and jogging, you added slower acceleration for these but I needed to remove something from the pendant from config, will search for this and include.

Let's focus on the HuanYang VFD first, shall we? That one is blocking, HB04 accelerations are not. 

Since the wiring and VFD configuration worked fine with 2.7 we have two possibilities for the hardware setup:
- Configuration is correct, issues are purely software related.
- Configuration was not correct, and some setting was not important with 2.7 while it is with 2.9

Does anyone know about such a setting? I am not too familiar with the HY-VFD component. 

@SvenH: can you:
- Check the setting of VFD parameters PD001, PD002, PD163, PD164, PD165? They should match this document: linuxcnc.org/docs/html/man/man1/hy_vfd.1.html
- Check that D+ and D- lines from the USB->RS485 converter match the corresponding terminals on the VFD. The CRC errors could be related to + and - being swapped.  (here is someone else with similar issues: forum.linuxcnc.org/49-basic-configuratio...h-hy-inverter#148533)
- Paste the hy-vfd component instantiation from your postgui HAL here too so others can have a look. 


Then about the software. The hy_vfd component seems to have changed 2 months ago: github.com/LinuxCNC/linuxcnc/tree/master...r_comps/huanyang-vfd
Seems unrelated, but could that be causing issues?
