How to make a wired connection to a device with only a USB port...

   A wired connection will almost always be faster than a wireless one. Calling ahead to inquire if an ethernet jack is available may or may not assure you get one. Also, a wired connection is definitely more secure than a wireless one. If your device has no ethernet jack, you can purchase a USB to ethernet converter from Amazon for $13.99. As and alternative, you can consider traveling with an inexpensive wireless router that you can plug into the hotel's ethernet jack and broadcast to your device. Although this might seem counterintuitive, your "private" wireless network, properly configured, will be invisible from others, immune from hacking and you will be the sole user which will maximize the bandwidth.
