I want to copy files from a computer with USB 2.0 support to an external drive with USB 3.0 support, but do not trust that the external drive is free of malware. Can a USB 3.0 device initiate communications with a USB 2.0 computer upon connection?
I have a late 2009 iMac running Mac OS 10.8. The tech specs state USB 2.0 hardware support. Someone sent me an external drive with USB 3.0 support, but I don't necessarily trust the device is free of malware. The Wikipedia page for USB states that USB 3.0 introduced support for device-initiated communication (i.e. an external device connected to a computer via USB 3.0 can start sending commands over the wire without waiting for any request from the computer).
I realize I'm being a little paranoid, but the question is also motivated by curiosity. Thanks for any feedback!
