Hello, I put my memory stick into a USB hub. The hub did not recognize the stick, but when I put the stick into the USB Port on my PC, the PC didn't recognize it either, can I reconnect to my memory stick?
I don't understand, you directly plugged the memory stick into your USB port? How is that possible?
In any case, I can only suggest you try another card reader. Or you can look for someone with a Sony device that supports memory sticks, and try reading your stick there to check if it still works.
