I have a Samsung Galaxy Tab and a PC. When I connect the Tab to my PC via USB, it won't detect it (no sound to indicate insert of USB). I checked the ports and they're working with other devices. I looked at My Computer but the storage device is not there. I also looked at device manager but there ain't any relevant device or unidentified ones. I also tried using Kies but it kept telling me to connect a device although I had already did so. This is my device info: Model: GT-P7500 Android: 4.0.4 My PC: Acer Aspire M3920 Windows 7 Home Premium Intel Core i5-2300 6 GB RAM 64-bit OS Thanks for your help.
