So I had to add support for HW of mine (SATA_VIA, PATA_VIA, disabled the
radeon firmware stuff, and, most importantly, enabled UHCI, which is what
is on machine I am using now for testing), and disconnect-connect cycle
works nicely:

usb 3-2: USB disconnect, address 3
usb 3-2: new low speed USB device using uhci_hcd and address 4
input: mouse USB mouse with wheel as /devices/pci0000:00/0000:00:10.1/usb3/3-2/3-2:1.0/input/input6
generic-usb 0003:05B8:3091.0004: input,hidraw0: USB HID v1.10 Mouse [mouse USB mouse with wheel] on usb-0000:00:10.1-2/input0
input: mouse USB mouse with wheel as /devices/pci0000:00/0000:00:10.1/usb3/3-2/3-2:1.1/input/input7
generic-usb 0003:05B8:3091.0005: input,hidraw1: USB HID v1.10 Keyboard [mouse USB mouse with wheel] on usb-0000:00:10.1-2/input1

so still no BUG from kobject refcounting, and the hidraw numbers are the
same. The major difference seems to be that I am using UHCI and you have
your HID devices connected through OHCI, is that correct?

Alan, does the system you are seeing this bug on also have HID devices
connected through OHCI?
