There is no record of such events in either `/var/log/syslog` or via `dmesg`. I'm running 10.10 on an Acer Aspire 5742 laptop. It may be relevant that both my HECI controller and SMBus show up as `UNCLAIMED` in the output from `lshw`. They are both listed as being `/^\s*product: 5 Series/3400 Series Chipset (HECI|SMBus) Controller/`. I'm booting with the `acpi_osi=` kernel argument. This, or a different problem resulting in USB devices not being detected, has happened once before, on 2011-03-12. I rebooted in order to be able to use newly connected USB devices. When the previous event occurred, I was not using the acpi_osi= kernel parameter. I was using the kernel package `linux-image-generic 2.6.35.27.35` (or possibly an earlier one, depending on when/if I rebooted) at that point; I have since upgraded to `linux-image-2.6.35-28-generic 2.6.35-28.49`. Since my last reboot I have plugged and unplugged numerous USB devices multiple times without any issues. Note the address `79` on the above syslog messages. I tried $ sudo modprobe -r usbhid ; sudo modprobe usbhid This logged the following to `/var/log/syslog` Apr 1 00:41:10 gatsby kernel: [450189.768916] usbcore: deregistering interface driver usbhid Apr 1 00:41:10 gatsby kernel: [450189.768960] usbcore: deregistering interface driver hiddev Apr 1 00:41:10 gatsby kernel: [450189.823210] usbcore: registered new interface driver hiddev Apr 1 00:41:10 gatsby kernel: [450189.823246] usbcore: registered new interface driver usbhid Apr 1 00:41:10 gatsby kernel: [450189.823250] usbhid: USB HID core driver but otherwise had no effect: newly-connected USB devices still do not work, nor are any syslog messages generated in response to their connection. I tried connecting devices to two different USB ports on different sides of the machine, both to the same non-effect.
