This is crearly not a problem with the device since you said that it is properly working on other computer. first, we need to know if there’s anything wrong with the usb port. does other device works when used with that port? secondly, you might want to try to fully reset the device. this is common with the connect. just press and hold the power button for about 15 seconds and after that, try it again.
If you can get ahold of another device that communicates via MTP, you could try it on your PC just to make sure that the problem is the MTP installation, and not something hardware-related.
The MTP porting kit contains MTP test tools … you might want to try those.
But, I’ve seen other posts that imply that if you configure the MTP porting kit incorrectly, you can actually disable MTP on your PC. So I would recommend uninstalling the MTP porting kit, and then reinstalling WMP 11.
