i dont think that is true.. the cable supplied with the dx160 is bi directional, which mean it transmit charge and data, usb dac is another thing, i still cant figure what is the reason
using the original cable, u can still transfer file into the internal storage but the usb dac mode will turn out as unrecognizeable icon, and the icon will only occur if u use usb 2.0 port, not 3.0 or 3.1. for storage mode usb 3.0 will detect the storage same as usb 2.0 port but when u turn in dac mode, nothing will happen, no icon or anything
people said that is a cable issue, and it does work by using samsung original cable, which have the same length as the original one,
people said its driver issue, whereas i connect to my laptop usb 3.0 without installing any driver and it detect the dac mode instantly
whereas on my pc it wont detect until u install the driver given from the website, only works on usb2.0 back on the motherboard
what i see here is hit and miss, u just try any possible way to connect in dac mode, no standardize way to tell u the steps required
