Re: [9fans] USB mouse not working

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.
