Hello,
Usually that error pops up because the USB connection is dropping on either the hardware or software side, so I want to narrow a few things down before we start trying fixes.
- What model is the phone you are trying to transfer from?
- Do you notice if the phone screen is locking or going to sleep right around the time the transfer fails?
- Also (I know it worked last week) but do other USB devices still work completely fine in that exact same port on your PC?
Let me know so I can pin down exactly what is causing it.
