See

The problem file/lib is on my Xubuntu systems:

uvcdynctrl
uvcdynctrl-data

And, I have zoom, cheese and Guvcview.

And, I have the troublesome log file. An entry seems to be made each 
time I video chat. Going back a year, the log file is at present 140K.

So, manageable for now.

PS- Always good to periodically take a look at /var/log/ to see if the 
log files are ballooning. Also (because of systemd):

# To view systemd log in reverse order (newest entries first) 

 

sudo journalctl -r 

 

# To view disk usage for log files 

 

sudo journalctl --disk-usage 

 

# To clear up disk space, use the --vacuum-files option, which deletes 
all but
the specified number of journal files. For example, to retain only three 
files:
 

sudo journalctl --vacuum-files=3
