commit d73a9b3001f29271c2e9f2a806b05a431c5d9591 upstream.

Add an unusual_devs entry for the Samsung YP-CP3 MP4 player.

User was getting the following errors in dmesg:
usb 2-6: reset high speed USB device using ehci_hcd and address 2
usb 2-6: reset high speed USB device using ehci_hcd and address 2
usb 2-6: reset high speed USB device using ehci_hcd and address 2
usb 2-6: USB disconnect, address 2
sd 3:0:0:0: [sdb] Assuming drive cache: write through
sdb:<2>ldm_validate_partition_table(): Disk read failed.
Dev sdb: unable to read RDB block 0
unable to read partition table

[PG: change USB_ --> US_ to match 2.6.34.x naming conventions]
