    I was reading more about USB ports on the Tesla as I'm thinking of "expanding" the ports on the Model S to passengers (read "kids") in the rear seat (e.g., let them plug in USB devices to play their music) in addition to charging devices. Along the way, I found a few threads that had to do with the USB ports in the Tesla and thought it may be useful to others to have a compilation as well as my own investigations.


    Each Tesla USB ports provide 1 amps at 5V, and both are remain "on" even when the power is off (unlike the 12V plug).

    See my upcoming post with full details coming...
    Tested with travel, un-powered generic USB hub, and powered USB 3.0 hub.
    Result=working with
    mice (wired USB)

    USB Keyboard and Mouse

    Result=working with mice (wired USB), not working for keyboards

    USB DRIVES FOR MUSIC (AKA "thumbdrives" and also SSD's)
    Small question about using a USB stick to play music...
    Hardwiring a 12V or USB-powered SSD - possible?


    MODEL S EXPERIMENT: Plug in a USB wifi adapter in the usb socket,?

    Result=not working

    Proper way to format USB thumb drive?

    Formats supported
    YES: Fat, Fat32, ext3, ext4.
    NO: exFAT

    Recommended Formatting Software
    Windows: Free Partition Manager for Window PC | MiniTool Partition Wizard Free Edition

    Special characters in file and folder names can cause the Model S to choke

    Has Anyone Implemented USB for Rear Seat Passengers?

    Let me know if I'm missing anything, but I know about the floppy drive and older USB devices working and I just need to find the post. I didn't post anything outside of the TMC website, but I can if I don't find the information repeated in a thread here.

    Mouse and drive worked on both hubs (cursor was movable, music was detected), and funny enough is that if you turn off the Tesla using the screen, you can "wake it" by moving the mouse, like you can if you touch the screen--not surprising because the computer was probably in "sleep" mode.

    I haven't plugged in multiple USB drives to see what happens, but I will tomorrow and see what happens.

    Miscellaneous results note:

    Before anyone asks, yes, I did try plugging the USB cable of each of the hubs to USB jack of the other to see if the Tesla could handle multiple layers:

    1. Mouse->USB2->USB3->Tesla: Works!
    2. USB Drive->USB2->USB3->Tesla: NO
    3. Any device->USB3->USB2->Tesla: NO

    I didn't have time to mess around more with it because I don't think anyone really needs to stack multiple hubs, especially because you can probably just buy a 7-port hub if you need that many or even just get two hubs (one for each Tesla USB port).

    I have tried a Netgear/Sierra 763S Wifi hotspot that also can offer a tethered network connection over USB but the Tesla did not appear to be able to connect to the network over USB. Of course it can connect to the hotspot via Wifi and give you an LTE connection.

    I am wondering if the Model X will have more backseat connectivity?
