$ sudo screen /dev/ttyUSB0 115200
[screen is terminating]

When I input command above, the output is really strange as below.

I just want to connect an USRP device. Could somebody tell me the reason for this output?

There appears to be a disconnect between what you think screen does and what it actually does. screen creates virtual terminals. It looks to me like you are attempting to connect screen to an actual terminal via a USB serial port. The reason you are getting the error you receive is that screen is attempting to execute the program /dev/ttyUSB0 and then get out of your way. This may be occurring because /dev/ttyUSB0 does not exist as a device on your system. You can determine whether the device you are attempting to connect to exists by issuing the command ls /dev/ | grep ttyUSB0. No output means not there. For more on screen see either the the help page, the project page, or man screen. You might also benefit from this page which includes links to some handy tutorials.
