I found that my computer only sometimes recognized my Sony Ericsson W300i phone as being connected with this cable, it also seemed to transfer slow as if not at USB 2 speed.It was so inexpensive as not to be worth returning.I ordered another for less than $2 (plus shipping) from a different vendor and that one works fine and is fast. (I looked for one that specifically said DCU-60 and said it supported USB 1 and 2.)So I still came out ahead over paying $16 or more to Sony Ericsson for one..
