The tx urb described is also for IR data TX.
IR TX is one primary function/purpose of the device.
It happens that the urb/endpoint for IR TX is the same urb/endpoint for
mceusb device commands.

The same is found for IR data RX.
The urb/endpoint for IR RX is the same urb/endpoint for mceusb device
responses (to commands).

My intent is to try and better word several of the USB layer messages,
and avoid confusing Microsoft MCE terms in those messages.

The original "(request) urb" phrases expand to "request USB Request Block"
and "<blank> USB Request Block" which are particularly confusing, and
non-specific, respectively.
