A cheap way to get a USB CAN Bus interface is the Adafruit Feather M4 CAN Express board. The SuperCAN project support it sice firmware release v1.0.14. After build and install the linux driver set it up like a common CAN USB interface. SuperCAN also supports CAN FD may be interesting for the new BOSCH Smart System.

For USB2CAN Adapter like CPC-USB
ip link set can0 type can bitrate 500000
ip link set up can0
# can0 = CAN-Bus Interface
cansend can0 061#00
python3 -m pip install python-can
Use can_viewer.py to get an overview of CAN-Bus activity
can_viewer.py -i socketcan -b 500000 -c can0
With cannelloni you can stream CAN Bus over UDP
# sudo apt install cmake git libsctp-dev lksctp-tools
# sudo ldconfig
git clone https://github.com/mguentner/cannelloni
cd cannelloni
cmake -DCMAKE_BUILD_TYPE=Release -DSCTP_SUPPORT=ON
make
sudo make install
sudo ldconfig
# sudo apt install linux-modules-extra-$(uname -r)
sudo modprobe vcan
sudo ip link add name vcan0 type vcan
sudo ip link set dev vcan0 up
