Christopher, My USB listing is attached. As you requested, I unplugged all USB devices first, then plugged in the mouse device (note important details below) and then executed "lsusb -v", with sudo of course.
Please note that this problem is specific to the mouse, not to Gateway DX4860. This computer system came with its own two-button mouse which I immediately replaced with 9-button Microsoft Wireless Laser Mouse 5000. To be precise, this mouse is part of a mouse+keyboard combo. The accompanying keyboard device is Microsoft Wireless Comfort Keyboard 4000. Both mouse and keyboard are wirelessly connected to the same USB transceiver. It is the USB transceiver device that I unplugged and then plugged back before executing "lsusb -v". I should perhaps note again, just for the record under this bug report, that the proposed fix in LP: # 926917 worked perfectly for me on LTS 12.04, completely fixing the problem with horizontal scrolling. ** Attachment added: "lsusb-v.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1260513/+attachment/3928466/+files/lsusb-v.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1260513 Title: [Gateway DX4860] Horizontal scrolling is broken with specific external mouse device Status in “linux” package in Ubuntu: Incomplete Bug description: horizontal scrolling is broken with specific external mouse device.
