Debian – No /dev/hidraw device when I plug in a Yubikey

I have a Yubikey NEO, and I'm trying to get it to work on Debian.

When I plug it in, I get udev events, but no /dev/hidraw? device.

Here's what I know so far:

cat /boot/config-$(uname -r) | grep CONFIG_HIDRAW) gives:

CONFIG_HIDRAW=y

lsusb -v -d 1050:0211 gives:

If I run udevadm monitor as I plug and then unplug the Yubikey, I get:

monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[7941.975349] add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)

UDEV  [7945.488620] remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)

I have added udev rules, as recommended here and cat /etc/udev/rules.d/70-u2f.rules gives:

ACTION!="add|change", GOTO="u2f_end"

#KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1050", TAG+="uaccess"
ATTRS{idVendor}=="1050", GROUP="plugdev", MODE="0660"


LABEL="u2f_end"

(This didn't work when the commented line was uncommented either.)

I've tried installing libhidapi-hidraw0, but that hasn't seemed to work either.

I've also tried installing and running the Yubikey NEO manager, but both it and the yubikey personalization tool don't think any Yubikey device is plugged in, which why I think the blocker is the lack of a /dev/hidraw0 device (or something at a similar level).

I've reached the limits of both my knowledge of Linux and my ability to Google for solutions, so both further debugging suggestions and (if you know it) solutions would be helpful.
