I have recompiled the xhc-hb04.cc with the deviceID EB6E as well as adding etc/udev/rules.d/90-xhc.rules with the altered deviceID. I have had to comment out quite a few lines in the HAL config file referring to extra axes. Linuxcnc now runs without error but the handset still does nothing. :dry:
I have run
from the command line and, after creating the pins, it fails with
Code:
libusb error (libusb couldn't open USB device ...)
Living life dangerously I then tried running as root...
A partial success!!! xhc-hb04 now working and streaming rows of data on each button press. Not sure if I need to do anything to stop
Code:

However, I have also found this on Planet CNC - which says that the #_wc_frac is 8bit for the HB03 and 16bit for the HB04 as the former only displays to three significant figures. This sounds worrying to me as I am not a programmer and have not the faintest idea where to look to check this. Even more confusing is that my model displays not 2 or 4 but 3 significant digits!
#_wc_frac - it is 8bit for WHB03 and 16bit for WHB04 ... it is simple whan you look two display max frac part for WHB03 it is .99 and for WHB04 it is .9999 ... this value also have a SIGN bit if value is negarive you must set most significant bit to 1... little example:
WHB03
our X position is: -117.33
we put 117 to x_wc_int
we also put 33 to x_wc_frac
we have negative value... we also need to set most significant bit of x_wc_frac to 1...
Code: Select all
Code:
x_wc_frac = x_wc_frac | 0x80;
WGB04
our X position is: -220.3345
we put 220 to x_wc_int
we also put 3345 to x_wc_frac
we have negative value... we also need to set most significant bit of x_wc_frac to 1...
Code: Select all
Code:
x_wc_frac = x_wc_frac | 0x8000;
How can I sort out the presumed permissions problem(s), what do I need to do to manage the 8bit vs 16 it words and how far away from a working solution am I? If this needs much more work it is definitely on its way back to the seller!
