Kernel does not detect Hardware / Software or Hardware fault
4
My Linux kernel (I tried several here from stock 2.6, 3.2 and 3.5 as well as a custom 3.7.3 one) does not detect my synaptics touchpad - or I am too dumb to find it. I looked into: dmesg, lsusb -v, lspci -v, lshw, /dev/input, /dev/bus/00x/ (...)
It shows me several internal usb root hubs and integrated rate matching hubs, my pendrive and optical mouse but nothing else of interest.
Now, as for the question: Is it possible that the kernel does not detect certain hardware if there is no driver available? As far as I understand it, the kernel should at least report some unknown device at some hardware address.

This question came from our site for system and network administrators.
synaptics touch pads are supported since ancient times so either the touchpad is turned off or simply broken. Laptop make and model? And quite simple solution, have you simply tried installing Ubuntu?
– Hubert Kario
Jan 20 '13 at 10:48
Well Ubuntu live runs out-of-the-box for any device - no touchpad there either. I just received the Laptop so my first quess is a faulty or simply not plugged in touchpad as well. But my question actually aims more on the basic principle: Is it possible, that the Kernel does not show connected and functional hardware?
– 0815ZED
Jan 20 '13 at 10:54
Yes, if it doesn't know how to detect it (when it uses some non-standard buses or buses that don't support auto-detection). Serial devices the kind of thouchpad would fall into this.
– Hubert Kario
Jan 20 '13 at 11:02
Recent laptops have ways of disabling the touchpad, maybe it doesn't work because of that?
– vonbrand
Jan 21 '13 at 4:03
guys, thanks for making it clear. @vonbrand: I thought of this too, didn't find a bios setting and fn+toggle does not work. xbindkeys reports unknown key...

My Linux kernel (I tried several here from stock 2.6, 3.2 and 3.5 as well as a custom 3.7.3 one) does not detect my synaptics touchpad - or I am too dumb to find it. I looked into: dmesg, lsusb -v, lspci -v, lshw, /dev/input, /dev/bus/00x/ (...)
It shows me several internal usb root hubs and integrated rate matching hubs, my pendrive and optical mouse but nothing else of interest.
Now, as for the question: Is it possible that the kernel does not detect certain hardware if there is no driver available? As far as I understand it, the kernel should at least report some unknown device at some hardware address.

synaptics touch pads are supported since ancient times so either the touchpad is turned off or simply broken. Laptop make and model? And quite simple solution, have you simply tried installing Ubuntu?

Well Ubuntu live runs out-of-the-box for any device - no touchpad there either. I just received the Laptop so my first quess is a faulty or simply not plugged in touchpad as well. But my question actually aims more on the basic principle: Is it possible, that the Kernel does not show connected and functional hardware?

Jan 20 '13 at 10:54
Yes, if it doesn't know how to detect it (when it uses some non-standard buses or buses that don't support auto-detection). Serial devices the kind of thouchpad would fall into this.

Recent laptops have ways of disabling the touchpad, maybe it doesn't work because of that?
