How's the weather down there?
I haven't tried, but it may be possible using the following technique.
Let me know if you need more help doing any of the steps:
1) Using ruby dl, connect to setupapi.dll and kernel32.dll
2) Call the function CM_Locate_DevNode to get the device handle for
the usb drive.
3) Call the function CM_Request_Device_Eject to stop the usb device.
You'll need to do a google search of microsoft.com for each of those
functions to know how to call them.

That isn't really a Ruby question so much as an "is there a
library/API to do this and can I use it from Ruby?" question. (If
the first answer is yes, the second answer is a qualified yes,
though you might need to write a C extension.)
What specific USB device are we talking about, and what do you mean
by "switch off"? Is this something you already know how to do from
another language?

Did you get my first reply that specified the functions you (likely)
have to call?
