I can also comfirm this bug on Ubuntu 6.10 with Logitech Elite keyboard and MX900 combo (both USB)
Here is how it works for me. When I boot into Ubuntu with bluetooth dongle pluged in, mouse and keyboard stops working. When I unplug USB from the bluetooth dongle Ubuntu loads fine, keyboard works, mouse doesnt (mouse uses USB, keyboard PS2). Now, if i plug in USB dongle back into to my computer, my mouse starts to work. I set "HDD_ENABLE = 1", didnt help. Amedee, I did what you asked Piotr to do. lsbus Bus 002 Device 003: ID 046d:c7xx Logitec, Inc Bus 002 Device 002: ID 0451:20xx Texas Instruments, Inc. TUSB2036 Hub When I type hid2hci, I get this Switching device 046d:c7xx to HCI mode failed (No such file or directory) If I set BLUETOOTH_ENABLED=0 Mouse and keyboard work fine, but I guess bluetooth doesnt work. -- Bluetooth Mouse and Keyboard Broken in Dapper/Edgy/Feisty https://launchpad.net/bugs/32415 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
