I have tried it but I cannot make it work. I run it under kernel 2.2.18 and 2.4.0 (SuSE 7.1 installation). If it can work, I effectively think its the better choice :-) > For a more low level access, /dev/hiddevX was designed. You shouldn't need > direct USB access.

The fact is I just want to make some research stuff about HCI with our engineer students for this year. For a futur and "nice" implementation of HID access, I find the best solution is to wait for more "stable" things under new kernel versions... ?
