 --------------------------------------------------
 as you can see
 this Mouse generate 2 HID protocol collection
 
 the first collection is
 USAGE PAGE Consumer(0xc)
 USAGE Consumer Control(0x1)[Consumer(0xc)]
 COLLECTION Application(1)
    REPORT ID 1
    ...
 
 the second collection is
 USAGE PAGE Generic Desktop(0x1)
 USAGE Mouse(0x2)[Generic Desktop(0x1)]
 COLLECTION Application(1)
    REPORT ID 2
    ...
 
 two collection describe a two protocol
 first protocol - AC line (Wireless Mouse from AC battarey)
 second protocol - Mouse movement
 
 
 an exists FreeBSD HID parser don't work with such collection
 to parse it used first collection, allways
 is't correct!!
 
 as example with this Mouse
 
 #kldload ums.ko
 #dmesg -a | grep ums
 
 ----------------------
 ums_attach: 3 buttons
 ums_attach: X   24/8
 ums_attach: Y   32/8
 ums_attach: Z   40/8
 ums_attach: B1  16/1
 ums_attach: B2  17/1
 ums_attach: B3  18/1
 ums_attach: size=3, id=1
 ----------------------
 
 the HID parser use first HID collection to parse Mouse movenent
 Mouse not work!!
 
 
 
 i'am fixx the HID parser
 to correct use HID collection
 after patch http://paradox.org.ua/work/fixx.tar.bz2
 ----------------------
 ums_attach: 3 buttons
 ums_attach: X   8/8
 ums_attach: Y   16/8
 ums_attach: Z   24/8
 ums_attach: B1  0/1
 ums_attach: B2  1/1
 ums_attach: B3  2/1
 ums_attach: size=5, id=2
 ----------------------
 and Mouse works fine!
 
 i think this patch fixx
 fixed all USB Mouse problem an *BSD system
