I was incorrect.  It seems that querying the master pointer does not
give the button state of the slave pointer even for normal mice.

I did some more digging on this today, and I found that an HP branded
wireless USB mouse has the same issue.  With this mouse (as well as the
logitech wireless mouse), the return from:

    xdev = XListInputDevices(GDK_WINDOW_XDISPLAY(rootwin),
&ndevices_return);

lists the USB device twice, but both have xdev[num].use == 3
(IsXExtensionKeyboard as defined in X11/XI.h).

I think the problem is that one of those devices should have the use
member set to 4.  The attached xinput list provided by Locke above shows
this correctly with one device as a pointer and one as a keyboard, but
I'm assuming the xinput program is using the XI2 API.

With a simple little program to list the devices and print the use
member:

13 devices found
Virtual core pointer: use is 0
Virtual core keyboard: use is 1
Virtual core XTEST pointer:  is a pointer
Virtual core XTEST keyboard: use is 3
Power Button: use is 3
Power Button: use is 3
G15 Gaming Keyboard: use is 3
G15 Gaming Keyboard: use is 3
Logitech USB-PS/2 Optical Mouse:  is a pointer
Macintosh mouse button emulation:  is a pointer
G15 Extra Keys: use is 3
BTC USB Multimedia Cordless Kit: use is 3
BTC USB Multimedia Cordless Kit: use is 3

While xinput prints:

      BTC USB Multimedia Cordless Kit         	id=14	[slave  pointer  (2)]
      BTC USB Multimedia Cordless Kit         	id=13	[slave  keyboard (3)]
