Every time I plug in any wired mouse recently, I get similar to the below on VCS1:
[1443270.286164] usb 6-1: new low-speed USB device number 15 using uhci_hcd
[1443270.454270] usb 6-1: New USB device found, idVendor=045e, idProduct=0083
[1443270.461874] usb 6-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[1443270.469328] usb 6-1: Product: Basic Optical Mouse
[1443270.476877] usb 6-1: Manufacturer: Microsoft
[1443270.501140] input: Microsoft Basic Optical Mouse as /devices/pci0000:00/0000:00:1d.0/usb6/6-1/6-1:1.0/input/input26
[1443270.509327] hid-generic 0003:045E:0083.000F: input,hidraw0: USB HID v1.10 Mouse [Microsoft Basic Optical Mouse] on usb-0000:00:1d.0-1/input0
.. but no mouse functionality.
The last time I spent some trying to solve this, the final line that is now missing from the above, was No input driver specified, ignoring this device
I haven't tried a computer reboot, because I am interested in using this opportunity to become more acquainted with the mouse subsystem(s) of Linux.
Found Restart USB mouse driver? while writing up this question, but not sure how to try steps 2 & 3 of what this OP tried (Have restarted X, however - No change).
What should I look at next?
