Add Logitech Wireless as virtual USB HID (#349)

Issue (copy from Trac):
When testing the USB framework (mainline,1035) on my
desktop machine, I hit the following malloc assertion
in the usbhid task when having moved the mouse for
the first time after it attached:

assert_abort+93
malloc_area+1021
malloc_internal+198
malloc+32
usb_hid_report_path_append_item+23
usb_hid_report_get_sibling+124
usb_mouse_polling_callback+1000
usb_hid_polling_callback+158
—end of issue description

The device causing the trouble is
046d:c52b Logitech, Inc. Unifying Receiver
its interface 1 (mouse).

The virtual USB HID simulates plug-in of the interface.
That currently causes an assertion failure in usbhid driver
in a reproducible way (i.e. without having that particular
piece of hardware).
Following revisions shall fix the bug .
