Pressure isn't going to work without USB passthrough, even with the additions.

To get the USB to pass through you need write permission to the device. Either run VirtualBox as root or find the tablet in /proc/bus/usb/devices, then change the permissions on /proc/bus/usb/XXX/YYY to give the account running VirtualBox read and write permissions. On Ubuntu, running "sudo chown username /proc/bus/usb/XXX/YYY" should do it.

X is the bus number listed in the devices file, and Y is the device number.

thanks, that helps alot! whee~ photoshopie, ive missed you, my pal

This is hopeful... don't want to run as root. But could one maybe give an example of the device to chown.. I guess I'm not sure what device is associated with my tablet.

Thanks.

fktt,
maybe you could answer here... how were you successful? Are you running as root? Or, did you chown the associated device files. If the latter... could you explain how you went about identifying the files and your basic proceedure to allow your usb tablet to pass through. I'm using an Intuos3 myself. And, the main reason that I'm using VirtualBox is so that I can use Photoshop again with my pen.

If it weren't for photoshop, I'd never launch windows again. Any help appreciated. Thanks!

No help here?

when i open this devices file the contents are blank... :/

ahh, sorry for not answering sooner, I'm reminding myself how to do it right now.. will probably write a more proper 'how-to' about it later, bare with me..

fxtt,

Thanks for responding. I'm still not there and need the pen functionality in windows. Looking forward to your enlightenment. Thanks again!

I remember now..

actually what i have done is got it into a state where it does not give me an error message about the usb device,
but i doubt its possible to get the pressure to work, because i doubt the guest additions supports digital stylus's pressure,
and afaik trying to install any drivers to the vm-windows probably will give you a BSoD..

or at least it sure gave me a big ugly blue one..

but generally move, the tablet should be able to without any special tweaks..

if your planning to use it in apps such as Photoshop then you can manage by simply changing the pressure manually, thats not hard, and you can still get natural lines as you'll still be using the tablet..

@elvismagrelo: thats because its not supposed to be opened as such.. i think its more of a link or a placeholder that indicates the piece of hardware..

to find out witch devise to chown just enter this in the terminal:

Code: Select all

cat /proc/bus/usb/devices

it should give something such as:

the first two sections are from device [001] folder (/proc/bus/usb/001)
the third section there is from device [002] folder (/prog/bus/usb/002)
and the last one obviously is the device [003] folder (/prog/bus/usb/003)

but thats just how it is for my machine, yours might be little different structured

oh, and are you running ubuntu gutsy? if you are:

fktt,

Thanks again for any help!

the third section there is from device [002] folder (/prog/bus/usb/002)

I think that you meant that the first 3 devices were were all device one (bus1,2,3)?

I am indeed on gusty... thanks for the link. I have followed all of that advise already.

I guess what is holding me up is thinking that I can install wacom driver on the windows side and use their control panel. Judging from what I am reading from your response... you don't have it installed and you are using your linux (host) sensitivity adjustments.. that pass straight through? Is that right? I guess I didn't even check it out on photoshop to see if I already had the function. Duh?! I'll try it out later today.

Thanks !

Steve

as i said it might be different for you, but on my machine theres only 2 in the first folder..

well yes i tryed to install the driver but all i got from that was a Blue Screen of Death..

hshan wrote:you are using your linux (host) sensitivity adjustments.. that pass straight through? Is that right?

no as far as i know, the sensitivity doesn't pass trough either, would be cool if it did though..

i actually use gimp for texture painting these days, doest the job for that fine..

Oh, so you don't get pressure sensitivity in photoshop either. Ok.

I can use the pen fine in photoshop as per selecting, it seems to map out fine. I would really like to be able to enable pressure sensitivity. I'll keep messing around. If you or anyone else reading this, comes up with or has a solution, it would be greatly appreciated if you could take the time to share.

Thanks again for your help!
