I recently got a Vivid brand eBook reader as a gift from my sister on my birthday. I started it and read one of the in-built content. Now I wanted to get my favorite eBook in it and so I tried copying it from my PC to its microSD card. But when I connected the Vivid brand eBook reader to PC using the microUSB, it failed to get detected in the PC. There was no external drive being shown in My Computer which would suggest me that connection between PC and the eBook reader has been established. Can someone tell me what the problem can be here?
