The problem is that USB is not built that way.
You would have to develop your own USB device which is not easy.
To the PC it needs to be a USB keyboard and to the notebook it needs to
be another HID device.
This constitutes a bridge device for USB because it is impossible to
connect two USB buse
I'll bet you could actually build a USB serial to USB HID device. There
are some companies that make a tty level serial to USBHID keyboard chip
so you could take a USB-serial chip cross connect the tty-serial sides
of the chip and one computer would see it as a USB serial port and the
other wou
Not sure what protocol that uses but it could be specific to that cable

I don't think you'll find an off the shelf cable for doing that. Most of
them look like network devices to each of the computers. Can't the teacher
just take a floppy or a cd, or a USB Storage device?
