I have a Wacom Bamboo that works out-of-the-box on Ubuntu 11.10 (even pressure). The problem, though, comes when using it on VirtualBox.

If I don't allow VB to access it, it recognizes the tablet as a mouse and works well (the same as when you plug the tablet the first time in Windows [normally, not on VB] and don't install the drivers). However, when I install the drivers and allow VB to access the tablet via "USB devices" it becomes really slow. I get pressure-sensitivity in Photoshop, but in exchange of a lag of seconds.

The question is.. is there a chance to solve this or is this something inevitable when using a tablet through VirtualBox?

Sorry, forgot some info:

Virtualbox version is 4.1.8 (Oracle version, not the OSE), guest is Windows 7 (though I think it happened the same in XP).

Do Your Windows apps work normally or they are slow too? –  Misery Feb 3 '12 at 9:32

It's only happening in Photoshop, though I don't know if it happens in the other apps and it's not noticeable. MAybe it's a RAM issue? –  Cmorales Feb 3 '12 at 13:48
    
ok, did You give Your Windows more ram in VB settings? –  Misery Feb 3 '12 at 16:36
    
my guess is that on VB photoshop cannot use hardware support for Wacom device. –  Misery Feb 4 '12 at 12:10
    
I think I aimed at the wrong thing. More than a RAM issue (it has 2GB and shows a lot unused) it looks more as a graphics issue. Something related to the video memory, maybe. Can you explain what do you mean with hardware support? Thanks –  Cmorales Feb 5 '12 at 13:43

Try to use the options in Virtual Box like:

Settings -> System -> Enable... (tablet)

Also ensure you have installed VB Guest Additions and the VB extension pack. And be sure to enable USB 2.0 support in USB options

Please note that Windows 7 will recognize your tablet as a touch interface and you will not see the mouse moving (although you will still be able to click). To solve this, you must disable mouse integration.

I have the same as you there (appart from the UTC thingy, though I don't think that matters). 128MB of video memory, 2D and 3D enabled in "screen" USB enabled, with USB2.0 enabled too. I tried setting a filter (I read about it somewhere here) with no luck either. In system, I have the VT-x/AMD-V thing enabled, but not the other one (I don't know how to translate it from the Spanish "paginación anidada"). –  Cmorales Feb 8 '12 at 8:32
    
But did You install VB extension pack? In my case that solved the issue. Google translator says that "paginación anidada" is "nested paging". That might be useful but I don't think that is the issue here. Could You give the screen shots of Your settings? Especially memory and processor –  Misery Feb 8 '12 at 8:39

Well, maybe it is not Ubuntu/VirtualBox/Windows issue. Check this link please –  Misery Feb 8 '12 at 8:48

Weird, now it's working :S I need to disable mouse integration, though. I might have set that config when I was trying to solve the problem but not tried without mouse integration. I am going to wait to check if the problem shows up again and, if not, mark your answer as valid. –  Cmorales Feb 8 '12 at 9:11

Yes, it is so far. I am going to edit your answer with a remainder to disable mouse integration. –  Cmorales Feb 8 '12 at 9:29
