Can I view the history of connected usb?

12.04 usb devices

7,164

You can get something by using the dmesg command and filter it to only keep USB events.

dmesg | grep usb

7,164

Familiar only with C currently. Not abundant experiences in JAVA and C++. New beginner to Html V(Javascript+CSS+HTML)/Python and Bash. However, I have great interest in computer science knowledge like programming language, image processing, networking, software engineering... Since I don't study in computer science department, hoping experienced programmer can give me advice that how to become stronger in this domain.

I don't know Ubuntu or other linux distribution would record the connected USB

information or not. I mean does Ubuntu record the USB information as I plug it into the PC,

when I plug it out, does the record remains in system? If yes, where is the log?

If not, can I do this?

'dmesg' displays the buffer of messages from the kernel (not only about usb). You can clear the buffer with 'dmesg -c'. But if you plan to do this from a program, you can also memorize the timestamp of the last message and only keep what is after.

How to clean msg after certain timestamp? I want to know the command, and could you also provide me the doc(relevant sites) about the usage of this command? Thanks!!

For future reference: you can see "older" dmesg files at /var/log/
