Hi all, I have a laptop keyboard problem - it fails to reconnect the |
2 |
keyboard on opening after closing. |
3 |
|
4 |
MS Surface pro 4 with type keyboard. |
5 |
|
6 |
The keyboard connects correctly on bootup or resume from hibernate (when |
7 |
open). |
8 |
|
9 |
Close keyboard (removes power), open keyboard and it no longer works. |
10 |
Requires a reboot (or hibernate/resume) for it it to work again. |
11 |
|
12 |
On opening the keyboard, the kernel detects it, it shows up in lsusb. |

It looks like it changes input when reopening but the event framework |
29 |
fails to re-enumerate it. |

Ive tried restarting udev but no luck. |

Where should I look next? |
