Guys, could you please send me your .config with which you are 
experiencing the problem, so that I can try to reproduce it with it?

Attached.

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?

Correct. And I should add that it very easy to reproduce here; just
disconnecting the usb receiver triggers the WARNING.

Disabling USB_HIDDEV in my .config solves the problem (there is no
WARNING anymore when disconnecting the receiver).
