Post subject:  [QUESTION] - YubiKey not working in Netbook, works in Desktp

Hi there,

today I got a YubiKey Edge and tried if it worked with all my computers (with the preconfigured OTP in Slot 1):

- Desktop with Windows 7: working well (LED stays on + OTP is typed)

- another Desktop with Ubuntu 15.x: working well (LED stays on + OTP is typed)

- Google Nexus 5 with Android 5.1.1 + OTG Adapter: working well (LED stays on + OTP is typed - most of the time)

- Netbook (Samsung NC10) with Debian Wheezy: not working...

From the tests the YubiKey seems OK, but maybe you have heard from the problem before.

Here is what's not working:
When I insert the key into my Netbook, the green LED blinks twice and then stays off. "lsusb" hangs when it is started after the LED is off. If I start "lsusb" in the second when the LED blinks, the LED stays on and lsusb shows the yubikey as USB device. Only then will I get a /dev/hidraw* device. The problem is that even then no output is generated when I press the button. "xev" shows no key strokes.
In one case where I started "lsusb" while plugging in the YubiKey, it started blinking three times very fast, ~500ms off and again 3x on...

When I insert the YubiKey before an OS loads (in POST/BIOS), it also blinks twice and then stays off.

What I tried:
- power down, separate from power, wait some minutes -> no change
- update to latest Kernel of Debian Wheezy -> no change
- other USB port -> no change
- looking for power settings in BIOS -> only CPU power settings found

Do you have a hint what else I could try? It doesn't look like an OS problem but like a hardware problem with my Netbook but USB sticks are working fine.

Was there ever a solution for this? I just got my first keys yesterday and I'm unable to configure either of them on my Debian laptop. However, I used the Nano to login to this site. When I start the personalization tool, though, it doesn't detect either my Nano or full-size keys. Both are recognized fine on my Macbook.

just tried it again - no solution yet, so I don't use the yubikey anymore...
