If you are having trouble connecting your DexCom continuous glucose monitor to a computer so that you can use the DexCom Clarity Uploader, you must use the USB cable that comes with it.
If you use another, standard, normal USB cable you’ll be able to charge the battery, but not transfer data because your computer will not detect the CGM when it is connected.
What is special about their cable? I have no idea at all. This drove me nuts for a while… as a computer nerd, the “U” in “USB” should stand for “Universal” but apparently not in this case.
