I am running xp ,have been using a MP3player Xclef800 ,no software needed to connect this unit .Two days ago when I connected my player ,I got the message , Windows does not reckonize the device . The MP3 player works ok I can play record though line in etc. But it will not connect to the computer. cannot remove and reload firmware file as cannot get a connection between the MP3 player and the computer ,Any suggestions as to what the problem is or any thing that I can try would be greatly appreciated anchor4@optusnet.com.au
