hi hans, hi list ...

i'm currently trying to get |hid| working with my usb keyboard ...

first i have to say, that |hid| is working pretty good with the internal keyboard of my laptop ... but on my usb keyboard, i only receive data from the fancy multimedia keys (nextsong, mute, home, mail ...), but not of the normal keys ... the keyboard works fine, though (i'm currently writing with it)

any idea, what might be the reason?

thanks ... tim

are you sure that you are talking to the keyboard, and if so, to the
right endpoint of it? it may be that it is in use already, like the kernel
or x, and so you access another endpoint of that keyboard, in this case the multimedia keys? i have already seen such combination devices....

by default, if you have the event system enabled and allow for
keyboards on that, they are grabbed by the event system (which may block the hid
access). similar thing for mice: many configurations use /dev/inout/mice, which concentrates all connected mice into one single device.

I am pretty sure that X and the linux console open HID devices
non-exclusive, so that you can always get the data. It works that way
on Mac OS X too. [hid] only uses the linux input event system devices,
e.g. /dev/input/event?, other devices won't work since they use a
different data format (/dev/input/mice, /dev/input/js?, etc.).

I am working on support for grabbing devices by type, in addition to
device name, that will make things less confusing I hope.
