I have 2 philips gogear mp3 players do I need to have to different software(s) installed? it's not charging. it's the 2gb one.

If they are the same model you anly need to install the driver once for both ...and the charging problem might be from the usb slot and not from the mp3 player ...cause there is no way that both to have the same issue ..
so change the slot and try again ...pay attention if on connecting you do not need to confirm from the mp3 itself the tip of connectivity ...charging or ..pc communication ..
another thing that might be is that it is not charging when it is on storage connectivity ..and in this case click on the remove safe icon ...in the tray system (lower right on task bar ) ..and choose remove and select the device ..but leave it plugged..it will stop the memory communication and it is a chance that wills tart being in charging mode..But usually this kinda devices that charge via USB slot..start charging from the moment you connect them into a good slot ..no matter if the driver is present or not..
