I was recently given a Nokia N810 from my sister and all that came with it was the charger. I ordered a micro USB cable so that I could put music on my tablet. Do i have to have a mini SD card or can I use the internal memory? I have plugged the device to my pc numerous times and I am still unable to get my pc to even recognize that the 810 is even plugged in. Every other time I plug something into the USB port, an icon pops up on the taskbar with this tablet nothing ever happens. Even if I go to Start<My Computer< then all it shows are the drives like nothing is even hooked up. I'm thinking the cable might be bad, idk.... I just bought it..It says Nokia Micro USB data cable Model: CA-101D, compatible with N810?? wth???
