I understood this as a feature when, after using the Apple mouse with this charging port, I got a Logitech Bluetooth mouse as I needed a middle mouse button for one program. It happens to have a front facing charging port. The mouse worked well and I recommended it to colleagues. On occasions when the battery died, I left a USB cable plugged in and assumed I was using the mouse by USB. At some point I realized it was for charging only after wasting time on “i don’t understand, even after I turn off Bluetooth, the USB interface doesn’t work.” A few times since then I’ve helped colleagues troubleshoot by informing them that there is no USB data interface and they should be checking Bluetooth and not swapping out cables. In both cases (Apple and Logitech), a “charge only” label would have been nice.
