yeah, there are quite a number of different configurations but a, b, mini a and micro b are generally the most common and regarded as standard. finding cables for other configurations is a bit harder.
when i buy a camera i always check the connection. i'm not buying anything special as that results in future headaches. my biggest peeve is how even on large tablets they put the smallest connector which always breaks. i'd rather have a bigger thicker phone with a full sized usb plug than need to replace cables every 6 months due to plug wear. its likely planned failure to sell more products.
