Hello, I submit a bug on bugzilla.kernel.org and Greg Kroah-Hartman suggest to send it to that mailbox. The bug was registered as #72911 with the .config file ed. I paste the details here : ================================================================================ Hello, I am using a KVM switch between 3 machines, on 2 "old" machines all is OK, mouse and keyboard are detected, on the "new" machine nothing is detected. The keyboard is working but the mouse is KO. I try to make some traces with dmesg concerning the usb port connected to the KVM switch. I made the traces on 3 systems, the 2 which are working, the 1 which is KO. All machines were running 3.14.0-rc7 during the tests. 1) Machines where the KVM is working : 1.1) AMD 905e 16GB DMI: MICRO-STAR INTERNATIONAL CO.,LTD MS-7577/790FX-GD70(MS-7577), BIOS V1.17 02/18/2011 Output of "dmesg | grep usb | grep 3-1" [ 3.740906] usb 3-1: new low-speed USB device number 2 using ohci-pci [ 3.935144] usb 3-1: New USB device found, idVendor=10d5, idProduct=5000 [ 3.935442] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 3.935726] usb 3-1: Product: Combo Free KVM [ 3.936013] usb 3-1: Manufacturer: No brand [ 3.958344] usbcore: registered new interface driver usbhid [ 3.958636] usbhid: USB HID core driver [ 3.960367] input: No brand Combo Free KVM as /devices/pci0000:00/0000:00:12.0/usb3/3-1/3-1:1.0/0003:10D5:5000.0001/input/input2 [ 3.960744] hid-generic 0003:10D5:5000.0001: input,hidraw0: USB HID v1.10 Keyboard [No brand Combo Free KVM] on usb-0000:00:12.0-1/input0 [ 3.961316] input: No brand Combo Free KVM as /devices/pci0000:00/0000:00:12.0/usb3/3-1/3-1:1.1/0003:10D5:5000.0002/input/input3 [ 3.961688] hid-generic 0003:10D5:5000.0002: input,hidraw1: USB HID v1.10 Mouse [No brand Combo Free KVM] on usb-0000:00:12.0-1/input1 Mouse and Keyboard are OK. 1.2) INTEL CoreI3 3130 8Gb DMI: System manufacturer System Product Name/P8H77-I, BIOS 0809 08/01/2012 Output is [ 4.106241] usblp 1-1.4:1.0: usblp0: USB Bidirectional printer dev 4 if 0 alt 0 proto 2 vid 0x04A9 pid 0x10CF [ 4.106274] usbcore: registered new interface driver usblp [ 4.125872] usbcore: registered new interface driver usbhid [ 4.125875] usbhid: USB HID core driver [ 4.137615] input: No brand Combo Free KVM as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.2/1-1.2:1.0/0003:10D5:5000.0001/input/input7 [ 4.137766] hid-generic 0003:10D5:5000.0001: input,hidraw0: USB HID v1.10 Keyboard [No brand Combo Free KVM] on usb-0000:00:1a.0-1.2/input0 [ 4.138008] input: No brand Combo Free KVM as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.2/1-1.2:1.1/0003:10D5:5000.0002/input/input8 [ 4.138134] hid-generic 0003:10D5:5000.0002: input,hidraw1: USB HID v1.10 Mouse [No brand Combo Free KVM] on usb-0000:00:1a.0-1.2/input1 Mouse and Keyboard are OK. 2) Machine where the KVM is not recognized.
