#1889 closed bug (fixed)

USB plugs on IBM T60 docking station do not work

Description

I don't know where this bug might originate, maybe it's something with device management in general. The laptop is already plugged in the docking station, and for example the network cable needs to be plugged there, the plug on the laptop is then non functional. But USB devices have to be plugged in directly on the laptop, the docking station plugs do not work. I am trying to hook my KVM switch there (have not tried anything else yet), which is like another hub. If I need to supply any more info, please let me know.

Do you have any relevant syslog information? I don't know how exactly the docking station works. Maybe it is a separate controller that is somehow hot-plugged in or it is just a hub that links to a present port. If you have any other OS on the laptop you could try to find the topology when docked and undocked to see what really happens (lsusb under Linux or the device manager under Windows).

I have attached some hopefully interesting lsusb output. The Haiku syslog output will come later.
