[QUOTE="nilanjan118, post: 86559, member: 13902"] Yes, it's a bad design. We all have trouble identifying which way the cable will go in. I have now marked "UP" and "DOWN" on both my charging cable and OTG cable so that I do not have to microscopically examine the ports each time as illustrated in post #25 above. The trapezoidal shape on most devices actually ensures that you cannot force the port in the wrong way and damage the pins. In fact there is a term for such mistake proofing. It is Japanese in origin and is called [B][I]Poka-yoke[/I][/B]. Quite surprising that the Chinese designers didn't borrow this concept from their Japanese neighbors. [/QUOTE]
