Yes, in theory. You'd first need to set the moko into USB-endpoint
(instead of USB-host) mode, and you'd need to write some mad kernel
hax that make it show up as a keyboard, and you'd need to expose the
mad kernel hax to userland on the moko so your barcode scanner can
send data.'s really a whole lot simpler just to use TCP.

Why can't you run software on the laptop? Some sort of locked down
corporate situation?
