Dear Sir/Madam
At a trade fair I purchased an HP U8131-O USB optical mouse. It appears
to be a "MouseSystems" protocol and "auto" also works. The mouse works
fine but i can't get the scroll wheel to work. Here are the complete
specifications of the protocol:
>From cat /dev/ums0 - | hd
A 8byte word is sent everytime the state changes. Much of this is certainly
known to XFree but here it is:
Default (no action)
87 00 00 00 00 00 00 7f
| | | | | | | |
0 1 2 3 4 5 6 7
Byte 0 the buttons: 0x83 Left buttion pressed
0x86 Right button pressed
0x85 Centre (the wheel) button pressed
0x82 L + R pressed
0x81 L + C pressed
0x84 C + R pressed
0x80 all buttons pressed
0x87 no buttons pressed
Byte 1 X-axis 'left' 0xff
Byte 2 Y-axis 'down' 0xff
Byte 3 X-axis 'right' 0x01
Byte 4 Y-axis 'up' 0x01
Byte 5 Wheel 'up' 0xff
Byte 6 Wheel 'down' 0x01
Byte 7 End of Frame 0x7f
Personally, i don't see how 'mapping buttons' has anything to do with
this mouse. It may just be a handy way to express the config? This is
a rather obscure mouse, but except for bytes 5 and 6 X sees it. Using
'xev' I see nothing from the wheel no matter how I configure it. Do you
have an easy way to do the configure? Sure, I can mess with the 'ums'
driver and get it, but want I to make sure before I do that.
Thanks in advance,
Bill Squire
PS: Running an amd64 which I bootstrapped FreeBSD on. Almost everything
works, and fast without the kernel panics and core dumps reported from
the v5.1 amd64 release. You can't even cvsup with that software!
