FINALLY, THE SOLUTION
I have a brand new Megastick 511 USB 2.0 without FM, and I could get version 3.x firmware update done.
My PC config is...
ABit KV8 Pro Motherboard,
512MB kingston RAM,
Athlon64 2800+,
OS Win XP SP2 with every single update released,
but frankly, I don't believe this problem has anything to do with machine configuration, USB or OS issues. It's merely a question of doing the right thing. Of course, I'm assuming your USB is really 2.0 and you downloaded the right firmware and unzipped it to the MS-5511 folder, as stated in the manual.
Ok, folks. After having this very same problem for a few days, I finally figured it out. Yeah, I wanted this playlist feature this bad, and it's worth the price.
Problems were...
1- Device was not recognized as a USB 2.0 device, no matter the USB motherboard drivers were installed;
2- As soon version 3.x firmware updates were done, I got the old 'deadbrick' effect - oh, yeah, no lights or sounds out of the brand new player - which could be reversed with the old firmware, the one supplied with the CD.
What I did to have the playlist feature was...
1- Took the battery OUT;
2- Using the cable supplied, I pressed and held the play/pause button and kept it pressed until procedure was completed;
3- Inserted the cable in a USB;
4- Windows showed the old 'hey, this device could be faster, blah, blah' message - just ignore it, as I did!
5- Go to the MSI MS511 MEGA STICK Update program;
6- This is very important... at this point, it would be nice if the software could recognize the device, but IT DOESN'T! You will get a message saying 'Media state not started' or something like this after quite a while waiting. This mean it won't show your current firmware version! Once again, ignore it!
7- Well, since the 'start' button was there, I clicked on it, AND I WAS AMAZED TO SEE THE UPDATE BEING DONE! Ok, I didn't wanted to format the device, as it was full of good music, but even unchecking the format option, the software keep saying this had to be done in order to upgrade the firmware - a fair price;
8- As all the copying and writing and verifying processes were done, I knew procedure was over, as the new 3.x firmware version was showing, and I could finally copy more tunes into my 511-now-with-playlist device! Only at this point I released the play/pause button.
Now, when I connect the 511 to the PC, Windows continues saying the device could be faster, but the Update software recognizes it immediatly! And for 512MB of stuff, it takes around 12min to transfer - as it did before - just in case you wanted to know.
Enjoy, my friends!
