Hi Julien,
No, for me this is not an issue with current daily images, because
I've downloaded Testing .iso with Xfce from another site [1].
Unfortunelly, now I can not give full results of these commands, because
I do not have access to the keyboard.
But, a couple days ago, just before send message to this mailing list,
I have kept more or less results of some commands (also for dmesg, lsusb etc.)
with USB keyboard plugged. A complete results of commands, which You
have asked for, I will be able to post, unfortunately, in two or even more weeks.
Also I have posted some commands in my first message [2].
I will use pastebin.com website, because the results are long.(Note: only lsusb -v command has full result); http://pastebin.com/EmPF3vAd
I'm sorry Julien, for the problems, but they are not my fault.
Best regards!
