freebsd stable - Jun 2020 - IPMI KVM mouse in absolute/tablet mode?

I'm setting up an ASRockRack X470D4U2-2T
(https://www.asrockrack.com/general/productdetail.asp?Model=X470D4U2-2T#Specifications
<https://www.asrockrack.com/general/productdetail.asp?Model=X470D4U2-2T#Specifications>).

It's one of the few Ryzen boards with ECC support and an IPMI KVM (AST2500).

Working with the web-based KVM is working well, including installing FreeBSD
12.1 from the disk1 image through the virtual CD drive.

However, moused seems to not understand the absolute addressing employed by the
emulated USB mouse. The mouse pointer fails to move, and the dmesg output only
lists the Z axis:
ugen0.6: <American Megatrends Inc. Virtual Keyboard and Mouse> at usbus0
ukbd0 on uhub2
ukbd0: <Keyboard Interface> on usbus0
kbd2 at ukbd0
ums0 on uhub2
ums0: <Mouse Interface> on usbus0
ums0: 3 buttons and [Z] coordinates ID=0


When I switch from "Absolute Mouse Mode" to "Relative Mouse
Mode", the pointer moves, and the dmesg shows X, Y, and Z:
ugen0.6: <American Megatrends Inc. Virtual Keyboard and Mouse> at usbus0
(disconnected)
ukbd0: at uhub2, port 5, addr 5 (disconnected)
ukbd0: detached
ums0: at uhub2, port 5, addr 5 (disconnected)
ums0: detached
ugen0.6: <American Megatrends Inc. Virtual Keyboard and Mouse> at usbus0
ukbd0 on uhub2
ukbd0: <Keyboard Interface> on usbus0
kbd2 at ukbd0
ums0 on uhub2
ums0: <Mouse Interface> on usbus0
ums0: 3 buttons and [XYZ] coordinates ID=0

I couldn't immediately find anything about support for the absolute/tablet
mode.


Thanks,
Stefan

Currently ums doesn't grok absolute mice, however you can use utouch instead
- check out the misc/utouch-kmod port.

I've successfully used it with Supermicro IPMI - good luck :)
