Although, as I am trying to read the referenced bug, one of the reporters are saying that they touchpad is USB: SysFS ID: /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3:1.0 ysFS BusID: 3-3:1.0 Hardware Class: unknown Model: "Synaptics Unclassified device" Hotplug: USB Vendor: usb 0x06cb "Synaptics, Inc." so I am not sure how PS/2 device would interfere with that. Could you give me access to the attachments on the bug so I can take a closer look? And hopefully the original reporter will submit their data. Thanks. -- Dmitry
