I have two notebooks with the above mentioned problem, one is a Sony Vaio VPCS11B7E, the other a Lenovo T520.
On both systems I have the possibility to run Kubuntu 18.04 or 20.04 by switching with grub bootmanager.
The hardware I need to use with NAVIT car navigation system is a USB GPS mouse with U-BLOX chip.
The GPS mouse is detected in all cases: with lsusb I get
martin@VAIOMB:~$ lsusb
Bus 002 Device 006: ID 1546:01a8 U-Blox AG [u-blox 8]
There is no problem to use the gps mouse with Kubuntu 18.04, it is running with cgps, xgps and can be used in NAVIT.
The problems start with Kubuntu 20.04 where I still get the above mentioned answer from lsusb. But what is working in Kubuntu 18.04
- when I connect the gps mouse to the notebook it is recognized and gpsd is started in the background - is not working in Kubuntu 20.04.
What I found is that with both versions of Kubuntu the gps mouse is working: when I start
martin@VAIOMB:~$ gpsmon /dev/ttyACM0 the mouse is responding like this:

Remember: the gps mouse here is not usable.
The important difference is one line under Kubuntu 18.04 reporting => creating modem with plugin 'u-blox' and '1' ports <=
and the corresponding line under Kubuntu 20.04 is reporting => Couldn't check support for device '/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1': not supported by any plugin <=
This under Kubuntu 18.04 leads to the normal situation that gpsd is started in the background and can gather input from the gps mouse and deliver it to NAVIT.
Under 20.04 gpsd is NOT started when the gps mouse is connected but started with NAVIT but without connection to the gps mouse and can NOT work.
So the question is: what is the difference for the modemmanager between 18.04 and 20.04?
Where and how can I get and install the modem plugin for u-blox devices, that in 18.04 is existing although I didn't install it?
One thing in addition: to me it looks like this is NOT a Kubuntu but a Ubuntu problem because automated udev recognition and things like modem plugins do not come from Kubuntu. Maybe I will add the same thread in a Ubuntu forum.
Anyway: can someone please help with this?
Thanks in advance!
On both systems I have the possibility to run Kubuntu 18.04 or 20.04 by switching with grub bootmanager.
The hardware I need to use with NAVIT car navigation system is a USB GPS mouse with U-BLOX chip.
The GPS mouse is detected in all cases: with lsusb I get

There is no problem to use the gps mouse with Kubuntu 18.04, it is running with cgps, xgps and can be used in NAVIT.
The problems start with Kubuntu 20.04 where I still get the above mentioned answer from lsusb. But what is working in Kubuntu 18.04

May 22 11:22:58 VAIOMB systemd[1]: Finished Manage ttyACM0 for GPS daemon.
May 22 11:22:58 VAIOMB mtp-probe: checking bus 2, device 4: "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1"
May 22 11:22:58 VAIOMB mtp-probe: bus: 2, device: 4 was not an MTP device
May 22 11:23:01 VAIOMB ModemManager[711]: <info> Couldn't check support for device '/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1': not supported by any plugin
Remember: the gps mouse here is not usable.
The important difference is one line under Kubuntu 18.04 reporting => creating modem with plugin 'u-blox' and '1' ports <=
and the corresponding line under Kubuntu 20.04 is reporting => Couldn't check support for device '/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1': not supported by any plugin <=
This under Kubuntu 18.04 leads to the normal situation that gpsd is started in the background and can gather input from the gps mouse and deliver it to NAVIT.
Under 20.04 gpsd is NOT started when the gps mouse is connected but started with NAVIT but without connection to the gps mouse and can NOT work.
So the question is: what is the difference for the modemmanager between 18.04 and 20.04?
Where and how can I get and install the modem plugin for u-blox devices, that in 18.04 is existing although I didn't install it?
One thing in addition: to me it looks like this is NOT a Kubuntu but a Ubuntu problem because automated udev recognition and things like modem plugins do not come from Kubuntu. Maybe I will add the same thread in a Ubuntu forum.
Anyway: can someone please help with this?
Thanks in advance!
