You can save yourself a lot of aggravation by getting a USB2 media card reader/writer,
for your PC. Then hide the USB cable.
I have one of these in my PC:

I also have a number of this type around as well:

There is nothing you can do to the SD card using the USB1.1 interface in the JBL,
that you can't do much better using the USB2 interface and your PC, including
formatting of the SD cards.
