Red Hat Bugzilla – Bug 52758
USB mouse not detected in installer
Last modified: 2014-03-16 22:23:07 EDT
Description of Problem: We have USB Keyboard here that has a PS/2-style mouseport on it. You plug a PS/2 mouse in, and the keyboard makes the system see a USB mouse. This mouse is not detected in the installer. This may be related to Hotplug bug @ http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=52546 Normal USB mice are detected OK with USB mouse plugged into system.

So... are you willing to have it claim there's a mouse there even when there isn't?
I don't understand. Can you elaborate a bit?
Look at /proc/bus/usb/devices, both with the mouse plugged into the keyboard, and without the mouse plugged into the keyboard - are they identical?
Yes, they are identical. I may be overlooking something, but I fail to see how this would cause any adverse reactions by anything. So, unless there is something I don't know about, yes, I am willing to have it claim there is a mouse there whenever this keyboard is plugged in. Right now, the installer doesn't work anyway, because even if there is a mouse plugged in, the installer doesn't see it. Hotplug has been fixed to detect this mouse (see bugzilla # above).
The mouse does not show up as a USB device if I am reading this correctly. On any installed system does the mouse work? If so, what are the contents of /proc/bus/usb/devices?
The mouse works just fine on an installed system if you load "mousedev". The hotplug scripts weren't detecting it correctly if you hotplugged it (#52546), but that has since been fixed.
I forgot to mention that the cat /proc/bus/usb/devices at the beginning of the bugzilla entry was taken from a running system, but it looks exactly the same in the installer.
Well, among other things, if we changed this, and you attached this keyboard to a machine with no mouse, the installer would try to start X. :)
Well, as it is, it is even more broken than that. You cannot tell the system you do have a mouse when you do, so there is no way to get into X in the first place. Basically, people who don't have a mouse already have a workaround, and that workaround is to type "linux text" at the boot prompt. People who _do_ have a mouse have no way to tell the system this. I would rather have the installer load "mousedev" and assume a mouse is present, write a "readme" that says if you don't have a mouse, type "linux text" at the boot prompt, than take customer support calls because their mouse doesn't work in the installer. Basically, Dell will take more customer support calls if we don't have this feature than if we do. That is bad.
Its really too late to change this at this point, we're days from shipping. There is a workaround which is to do a text mode install. We can attempt to address this the next release cycle. Somehow a dell employee got assigned this bug, reassigning to Bill since this is a kudzu issue.
Not detecting mouse in Hampton Beta 2.
I cannot believe this is not getting traction since August. If that helps, I've got two Dell keyboards that they sent me. Bill, do you want them? Otherwise those are pretty good keyboards.
Fixed in kudzu-0.99.49-1... RPMS are at http://people.redhat.com/notting/kudzu/, if you want to look before it hits rawhide.
Sorry Bill, but I'm not quite following here. Does this new kudzu RPM fix the installer (anaconda) issue? How can I use the RPMS on your site to test the installer? I'd be very happy to get this tested if you can tell me how...
It will fix the anaconda issue once the loader is rebuilt against that kudzu-devel, and the new kudzumodule is put in the second stage... basically, to test anaconda, you'd need to add the kudzu packages to your tree and remake the install images.
And for your convenience, I've quickly put together a bootnet and update disk that should work with the beta released today on ftp.beta at http://people.redhat.com/~katzj/usbmouse so that you don't have to build your own trees for testing.
Tried out the bootnet.img/updates.img file posted by katzj and they work like a charm. Thanks.
