USB Keyboard doesn't work

[palimmo]

Hello. A few days ago I bought a SL640 Hama USB keyboard to use on my laptop with Ubuntu 12.04.
But I'm having problems, as it works one time out of 10!
While on my girlfriend's laptop, with Win Vista, always works.

Here are some infos:

~$ lsusb

Bus 006 Device 003: ID 04d9:1503 Holtek Semiconductor, Inc. Shortboard Lefty

As you can see, the OS recognized it but the keyboard doesn't react ... even the Caps Lock and Num Lock keys don't blink.
Regarding the legacy support (useful for GRUB), I have found no entry in the BIOS. But I'm not interested in it. I just want to use it in Ubuntu.
Help.

Thank you!

Well.. on the same laptop I have Win7 in dual boot. And I have to say that it always works on it.
In GRUB it works sometimes.
Surprisingly now I have booted my laptop: the usb keyboard hasn't worked in GRUB but it has worked since the ubuntu login! And now I'm typing with it.

So..potentially it works. And that's good. But I can't work in this situation. What should I do?
Thanks.

Well.. it means that Ubuntu has the right drivers and they work. But how to "load" them always correctly?

Here a dmesg when it works

Another example.
After several plug/unplug actions, now it works.

Here dmesg:
