[9fans] USB mouse not working

[9fans] USB mouse not working

[G B]

I have 2 IBM Thinkpad X60 laptops and one of them has Plan 9 from Bell Labs installed and the other has 9front installed.
I also have 3 USB mouse devices: ?A Dell optical mouse; A Lenovo optical ScrollPoint mouse; An IBM MUY101 3 button optical mouse.
The touchpad pointer works on both Bell Labs and 9front, but the USB mouse devices only work on Plan 9 from Bell Labs and not 9front. ?I purchased the Lenovo ScrollPoint mouse because I read in the 9front FQA it was recommended. ?Is there a binding I need to get the USB mouse to work with 9front?

hard to say.

i'd start by making sure the usb controller works. the most
common issue is that interrupts do not work due to broken mp
tables.

9front uses acpic interrupts by default, which can result
in usb not working when bios mp tables are broken. the work
arround for that is to specify *acpi= on boot which uses
acpi tables instead. alternatively disable apic interrupts
and switch to legacy PIC interrupt model with *nomp=1,
(this used to be the default of the plan9 from bell labs
live cd).

second is that 9front uses different mouse usb mouse/keyboard
driver that sets the mouse in non-compat mode and tries to parse
the report data according to the hid descriptor.

source: /sys/src/cmd/nusb/kb.c

to debug that, run: ps -a | grep kb to get the nusb/kb processes
program arguments (contains the usb address they are attached to)
and then kill the process. then start another instance of nusb/kb,
passing in the original usb address and the -d flag.

good luck.

a bit of an update, disabling one of the usb ehci devies "fixed" things
but i get a number of errors and warnings from epiowait() with this
format: "ehci %#p: io %#p qh %#p timed out (no intr?)\n".
things are not right, but at least the machine is working as a terminal.

i added some general code to disable arbitrary ehci devices.
also, i noticed that there's a smalloc() that really can't be counted
on as we're holding an ilock.  i'd rather panic on nil indirection
than just hang.

[9fans] usb mouse not working

i have a ehci-only system that seems to be recogizing the mouse, but
the mouse doesn't work.  one thing that stands out is that the "online"
light in the scroll button doesn't light.  i seem to have the kbd process running,
