USB port MSC mode malfunction

Hi:

I’ve got another issue going with a unit I just bought regarding “blips” or “skips” that occur while I’m playing music, but that’s another topic dealt (?) with elsewhere.

In an attempt to see if something was happening while I was transferring files, I changed the USB port mode to first the MTP mode and transferred a selection.  Seemed to be an improvement.  Went from 3 or 4 skips to 2 or 3, so I think there was an improvement.

Next I tried the MSC mode and then bad, bad things happened.  I got a error message on my PC, then the little unit’s screen went dark and I’m pretty sure I smelled something burning.  I quickly unplugged and checked the unit.  It was dead.  I packaged it for a return to the store when I thought to try a ‘reset’ by holding the on/off button down.  I held it down way past the 10 seconds and just when I was going to give up, the unit came back on.  Everything was still there so I set it back to the MTP mode and it worked as before.  I then tried the MSC setting again, and again the thing went dead and had to be manually reset.

Yes, I have the latest firmware downloaded into the unit.

Question: is this normal or is my unit defective?  Could this be why I’d getting ‘blips’ in my playback because there is something wrong with the USB interface circuits on the chip?

I think you got a bum unit. I’d return it and get another. No one else here has ever reported the ‘blips & skips’ problem you described in your other posts, and this player has been out for almost 2 years.

OK, here is the latest:

I didn’t want to take the player back without it having a “hard failure” that I could show the store people so I selected the MSC mode and kept plugging it in to my USB port.  Of course I’d get a error message each time, but when I’d unplug, the player would still be operating – which was something new.  I did this several times hoping something would burn out and sure enough, the player stopped working.  I did a reset and then started over and would you believe it, everything started working perfectly and I was able to access the file structure.

I downloaded a selection that had “blipped” on me before while in the MSC mode, unplugged and then played it.  Absolutely perfect, no blips or chirps and it sounded beautiful.  I am so happy.

I have now transferred all my music using the MSC mode and so far all selections are without annoying chirps on them.  I don’t know what I did or what happened inside the player’s chip, but as far as I’m concerned, both this mode problem and the blipping problem are solved. 

I just hope it keeps working.:neutral_face:

There is one thing I did (actually 10 things I did) and that is to “cancel” the error message each time it popped up until I got a connection and was able to access the file structure of the device.

As mentioned in the other thread, something ain’t right, but it works and I’m happy.
