Daisy USB do not create /dev/ttyACMx - it-slav - 2020-08-12
Hi
I have been using my daisy USB connected to ubuntu many years and versions and it has been working flawless.
When connecting to openplotter it does not create any new device.
/var/log/messages:

I guess I have to fiddle with udev rules to get it working.
I have connected a USB GPS and that works perfectly well.
I use openplotter "2020-03-24-OpenPlotter-v2-Starting.img" image
Tried to search the forum but could not see anyone else with similiar issue
Thanks

Not sure but It could be that the Daisy devices are another victim of this: https://forum.openmarine.net/showthread.php?tid=1807&pid=15187#pid15187
what is your kernel version?
RE: Daisy USB do not create /dev/ttyACMx - it-slav - 2020-08-12
Code:
pi@openplotter:~ $ uname -a
Linux openplotter 5.4.51-v7+ #1327 SMP Thu Jul 23 10:58:46 BST 2020 armv7l GNU/LinuxRE: Daisy USB do not create /dev/ttyACMx - it-slav - 2020-08-13
Reverting to an older kernel/firmware with:
Code:
sudo rpi-update bafd743eeb3e8a2a863936594cd7201a0af136faNow /dev/ttyAMA0 is created and I can connect to it with
Code:
minicom -b 38400 -D /dev/ttyACM0 -8Thanks

that confirms the source of your problem. Wait for the next kernel and try again, it should be fixed.
