Where do you switch the usb to MSC? That I don't get....

Usb mode is in settings push center button choose between msc or mtp....

MSC will allow you to see the expansion card mtp won't.....MTP shows you your music folder in the media folder thats where you put your music plus expansion.....If no usb mode the player is manufactored to be in msc mode.... make sure your usb 2.0 driver is installed....... Connect to the mother board.. MSC is best create a music1 folder and put music in there then there is no switching back and forth to mtp ms....MSC can sync the player and the expansion card

Hello,

When you're able to change USB mode in the display:
- From the Main Menu, select Settings > USB
- Select in "Auto Detect", "MTP" or "MSC": choose MSC for viewing the player as a removable disk.
When you cannot select MSC mode in the player's menu, force MSC mode with the player switches/buttons:
1. Turn device OFF.
2. Facing the hold switch: slide it to the right so an orange color would show, putting the device on Hold.
3. Connect the device to the PC with the provided USB cable.

note
In MSC mode: Before disconnecting the USB cable always go through the safely remove hardware icon in the lower screen of your computer on the right. Left click the icon to see all removable disks and left click on the removable disk drive letter of the player to disconnect: after the message you can take out the USB cable.
