Found something strange. I wanted to test the USB port so I plugged in a cable then set the link option to on and the sx mini reset itself. Once it came back up the link option was still set to off. I decided to remove the USB set the link option to on then plug in the usb cable and it reset again but this time did not come back. I had a moment of freak out so pulled the battery and replaced it and the sx mini is back to normal.
It seems to charge just fine so not thinking anything is wrong with the USB port itself.
Can anyone else give the link option a test to see if they see the same behavior?
When you go into link option to do an update you do basically reset the device. While at the same time having the Yihi software up on your pc and device connected to the USB you hit connect icon. Presumably you'd have already installed the drivers.
My Link option works fine but saying that I most likely will never use it. I would suggest you remove your battery then connect it to your USB and then run Yihi software. This seems to be less troublesome to me.
