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?
