How can I find the last time a particular USB device was connected?

I'm trying to piece together when I last used a USB flash drive which I've lost. If I can find when I last had it, it may help point to where I should be searching. Thanks!

depending on your OS, you can grep something from either /var/log/syslog or /var/log/messages or through journalctl.
to see older messages, check for /var/log/syslog.1 or /var/log/messages.1 or /var/log/syslog.1.gz or...
type

Code:

ls /var/log/

to see all these logs

to read a log you can use

Code:

less

(if the log ends with .gz you can use

Code:

zless

) . in there, type '/' to enter a search string. in there, type '-i' to change case (in)sensitive search.

at all times, you can use

Code:

man less
