Can not access the device when in Mode 5 - U2F/CCID composite device

[adiroiban]

If the device is set in U2F/CCID composite device from neoman ... or from ykneomgr itself I get

$ ykneomgr -m
error: ykneomgr_discover_match (-4): Backend error

I have Ubuntu 14.04

$ ykneomgr -V
ykneomgr 0.1.8

I can change the mode from neoman ... but even if CCID is enabled, neoman will not show the available applets

---

To reproduce set the device in other mode...ex 82

$ ykneomgr -m
82
$ ykneomgr -M 5
$ ykneomgr -m
05

# I then eject the device so that it will have the new USB id

$ ykneomgr -m
error: ykneomgr_discover_match (-4): Backend error

after device is plugged again the USB id is

Bus 002 Device 015: ID 1050:0115 Yubico.com 

Thanks!

Here are the screenshots from neoman for top+ccid and u2f+ccid

$ opensc-tool -l
No smart card readers found.

I can see the card reader when in otp+ccid mode

You almost certainly have an older version of libccid which does not have the latest PIDs for our devices. You can upgrade libccid, or just patch the device list https://github.com/Yubico/yubikey-neo-manager/blob/master/resources/linux-fix-ccid-udev
