Yes, it is normal.  USB uses a hub and spoke architecture.  You can have many devices connected to the same buss, but they all tie back to just one computer at a time.  That's important since USB not only moves data but also supplies power.  If two computers were connected, both supplying power, you could have issues with voltage differences.  Thumb drives and card readers will often have a built in cable or plug with a USB "standard A" connector that plugs directly into the computer, but that's because they don't use a separate cable.  Virtually all other USB devices use a cable with a "standard A" end for the computer and a "B" end for the device.  Most cameras, phones, etc., use either a USB "mini B" or "micro B" connector these days.  MTH had a little more room to work with on the TIU than on a cell phone, so they used a USB "standard B" socket.

USB Printer cable?  What's that?  The TIU requires a standard USB A to B cable, the same kind that is used for many devices, including printers.  I have external disk drives, a slide scanner, as well as a printer that uses that cable.

 

The A to B cable has the same power as one of the A to A cables, obviously the TIU interface has been designed to accommodate the presence of the 5V power coming from the USB B connector.
