USB device suddenly not recognized by hal_input was created by Wirewrap
Something has happened.
This LinuxCNC machine has been in use for a couple of weeks and my USB pendant has been working with hal_input as it was supposed to do.
The pendant is recognized by UDEV and assigned to group plugdev.
LinuxCNC 2.7.8
Now, suddenly hal_input is not finding the pendant. but hidraw2 still belongs to plugdev.
I tried with hidconfig to diagnose, it puts an asterisk on this device.
sudo hidconfig finds the device without an asterisk.
hexdump /dev/hidraw2 works without sudo!
Triedthis does not solve the problem.
What else can I try?

Did you get this fixed?
I had a machine that used to "lose" USB devices. I never really tried to get to the bottom of it, as it was a joypad only really useful for milling, and I stopped milling with that machine.
I would be tempted to try blindly tweaking USB settings in the BIOS.

Yes,
it is fixed now.
I tried some different idéas, and suddenly the pendant was online again. Not sure which thing was the actual fix.
