Turns out fedora23 worked on the same computer that I had it working
on with el7.  I tried it on several of computers:

el7: didn't work
el7: worked
fc23: didn't work
fc23: worked

The thing the non-working computers had in common was (from dmesg):

[12506.991024] usb 1-5: new full-speed USB device number 9 using xhci_hcd
[12507.561015] mceusb 1-5:1.0: Registered  with mce emulator interface version 1
[12507.561021] mceusb 1-5:1.0: 2 tx ports (0x0 cabled) and 2 rx sensors (0x0 active)

Whereas the working was:

[  407.226018] usb 2-2: new full-speed USB device number 3 using uhci_hcd
[  412.782038] mceusb 2-2:1.0: Registered TopSeed Technology Corp. eHome Infrared Transceiver with mce emulator interface version 1
[  412.782594] mceusb 2-2:1.0: 2 tx ports (0x0 cabled) and 2 rx sensors (0x1 active)

(Notice the xhci vs uhci and the lack of the specific model, as well
as "active")

There are a few reports about what seems like a very similar issue,
for example:

https://patchwork.linuxtv.org/patch/21648/

I'll post a message to the linux-media mailing list.
