I see the same problem, behaves somewhat differently on different machines/ports. I use two devices connected via two Logitech Unifying dongles on each of these computers, running latest 12.04.
On my desktop computer (Zotac amd64) I often need to unplug and replug (once) one or both devices when X starts. Then they work fine. This only started to happen after upgrade to 12.04. On Dell Latitude E 6510 both work fine most of the time, sometime I need to unplug, plug them. On Zareason Gazelle Pro notebook (Intel ia7) which has three USB ports - one high speed USB 3 and two slower USB 2 ports the device plugged in the USB 3 port always works, the device plugged in any of the slower ports usually does not, if I unplug and plug in again enough times it eventually starts working. When the device is not working I see same messages in kern.log: Jun 22 14:16:05 yummly-ubuntu-erik-gazelle kernel: [ 10.952065] logitech-djreceiver 0003:046D:C52B.0003: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-2/input2 Jun 22 14:16:05 yummly-ubuntu-erik-gazelle kernel: [ 10.952329] logitech-djreceiver 0003:046D:C52B.0003: logi_dj_probe:logi_dj_recv_query_paired_devices error:-32 Jun 22 14:16:05 yummly-ubuntu-erik-gazelle kernel: [ 10.952467] logitech-djreceiver: probe of 0003:046D:C52B.0003 failed with error -32 When the device works I see: Jun 22 16:34:57 yummly-ubuntu-erik-gazelle kernel: [ 1519.997025] usb 3-1: new full-speed USB device number 16 using xhci_hcd Jun 22 16:34:57 yummly-ubuntu-erik-gazelle kernel: [ 1520.019654] logitech-djreceiver 0003:046D:C52B.0041: hiddev0,hidraw2: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-1/input2 Jun 22 16:34:57 yummly-ubuntu-erik-gazelle kernel: [ 1520.021094] input: Logitech Unifying Device.
