Does any one has a good *.dat file for USA?

Try CHIRP (chirp.danplanet.com). CHIRP goes out and downloads the "recommended" frequencies, offsets and all, for your area.

It's the best software I've seen for programming my wife's Baofeng UV-5R, MUCH better than the software that Baofeng supplies on that CD.

EDIT: A Google search reveals that this is a common problem with the 888s. Here is a link to a thread about this (way too long to post here). Basically, common fixes are changing the device driver and/or the cable. http://chirp.danplanet.com/issues/4249
