2.6.36->2.6.37 USB regression, bisected to "USB: add driver for
Meywa-Denki&  Kayac YUREX"
Unfortunately, the device seems to have the same Vendor ID
and Product ID as YUREX leg-shakes sensors, and the
commit 6bc235a2e2 added the ID to hid_ignore_list.

I believe that we can distinguish YUREX and the Wireless Presenter
by device type. The patch below makes the driver ignore only
YUREX (bInterfaceProtocol==0), and recognize Wireless Presenter
(bInterfaceProtocol is keyboard or mouse) as generic HID.
(I don't have the Wireless Presenter, so not yet ested.)
