USB Connection, Device not recognized (but it charges)

I've got a BRAND NEW out of the box Forerunner 745 that wouldn't connect to 4 different Windows boxes. After I read this thread, I tried pushing and holding the USB plug into the back of the watch HARD. It worked. I had to hold it in place the whole time, or it disconnects. There is obviously a flaw in the cable/plug design.

I think it is a software problem (windows or watch FW). When problem occurs, simply let the watch plugged and reboot computer.

I had the same problem, and after reading all these posts, I pulled out the "second" cable provided with my 945 LTE. The computer recognized the watch. So..... that shows it's not the watch (thank God). I took the first cable, and sprayed the connections that go into the watch with alcohol directly, Then, plugged it back into the watch - it worked.  Always check for bad cables first. I've been an even videographer over 30 years, and more than half the time, it's time to replace cables. I knew some colleagues that every year, whether the cables were good or not, would replace his most used cables for this very reason.

Me to...been using the 945 for about 2 years...i smear small amount of the gel type hand sanitizer on the cable head and wipe off the access liquid with soft cloth, then connect to the watch..violla, it get recognised by the PC instantly.

I´ve just cleaned the contacts and it worked so fine.
