I'm not sure what's going on with g_multi for you there. But I will say this. There are other, probably better suited options for moving files over to the device.
I've used g_multi in the past and have always found it problematic for this platform. So personally, I dedicated a cheap netbook to operate as a server for the beaglebone(black), and just used NFS shares, and Samba for my dev workstation. Another option would be to use ssh file transfers, after running a ssh server on the beaglebone. It really depends on what you're trying to do, and your dev system.
