I would expect that access would only be available using the IP address, not by browsing. I have a WD HD TV Live that shares USB drives on the network. No password needed, only FAT32 (or maybe NTFS) formatted disks work.
That means if you select samba, then you'd access it with \\192.168.1.1\ and browse from there from MS-Windows. In a Linux world, smb://192.168.1.1/ is what I'd expect. Of course, if your DNS or /etc/hosts file has an IP/hostname cross-ref, then you CAN use the hostname instead of the IP.
I am able to mount the WDTV on Linux with this:
Clear as mud?
sudo mount -t cifs //wdtv/usb-drive /home/thefu/wdtv -o rw,uid=thefu
Of course, I don't have the same device that you do, so this stuff might not apply at all. Hopefully the examples will be useful to someone, if not you.
