Hans, Daniel, Hi again,
I made a 90-puredata.rules file in /lib/udev/rules.d/ containing the following line: KERNEL=="event[0-9]*", MODE="0660", GROUP="plugdev" The "evdev EVIOCGABS ioctl: Invalid argument" doesn't appear anymore but [hid] still can't recieve data from de /dev/input/event8 that is where my touchpad is located. I tried copying the 90.puredata.rules file to the old ubuntu udev rules directory (/etc/udev/rules.d/) but it didn't work either. I also tried both modes (0660 and 0666). Am I doing something wrong? thanks again, Diego. --- On Sat, 7/18/09, Hans-Christoph Steiner <h...@at.or.at> wrote: From: Hans-Christoph Steiner <h...@at.or.at> Subject: Re: [PD] HID problem in Xubuntu.

We will need to be careful with the permissions stuff, I don't want to be responsible for lots of people getting their machines pwned via pd ;) I imagine MODE=0666 is not necessary, for example, MODE=0660 with the plugdev group should work and be more secure. If you have something sketched out, how about committing it to the SVN, or posting it to the patch tracker. Or really whatever it takes to get people to contribute work on this stuff. I don't know the udev stuff really, so I don't have much to contribute there. I see no reason not to include the .rules file in the Pd-extended package, we'll just have to work out the security details if its going to be loaded by default. .hc On Fri, 2009-07-17 at 12:53 +0200, Daniel Wilcox wrote: > > Hi?
