I’ve had a Sansa C200 for a long time and have always used in in MSC mode (though I didn’t realize that until recently), where the player shows up as a separate drive letter in Windows XP. Recently I got the Sansa Clip for my wife and couldn’t get XP to recognize it; at least not until I used the trick of the hold button and pushing the center button while plugging it in. But I couldn’t leave well enough alone and tried to get it to operate in MTP mode. Well, I succeeded but now the computer won’t recognize my other player, whether it is set to ‘auto-detect’ or "msc’ mode (its two options).
To get the clip to work in MTP mode, I did several things, including installing Microsoft’s MTP Porting Kit and their MTP Enhanced Specification. I also installed WMP 10 and then the next I installed WMP 11 (I had been using version 9, though I use Real player most of the time). Anyway, I’ve then tried retracing my steps by uninstalling each of those things (using Add/Remove programs) but nothing seems to help. I even tried using System Restore but every restore point I tried eventually came up and said that the restore cannot be done (glad I wasn’t depending on that for something really serious).
I also did a bunch of XP security fixes (I don’t let Automatic Update work on its own) and I haven’t un-installed all of those yet but maybe I will. The fact that XP still recognizes my clip in MTP mode tells me that I haven’t quite gotten back to my original condition but I don’t know what else to try.
I’d appreciate any ideas. I’m getting tired of messing with this! Thanks in advance.
