Fwd: Problems with usb HID device on freebsd

[Riccardo Torrini]

I sent this message also to FreeBSD USB maintainer and to NetBSD
original author without luck, can you point me to the right direction?

TIA,
Riccardo.

I'm trying to interface my new APC (RS 500) with FreeBSD 4.8-STABLE but
I found some (a lot of?) problems:

# usbdevs -v -d
Controller /dev/usb0:
addr 1: self powered, config 1, UHCI root hub(0x0000), VIA(0x0000), rev 1.00
  uhub0
 port 1 powered
 port 2 addr 2: low speed, self powered, config 1, \
	Back-UPS RS 500 FW:30.j2.I USB FW:j2(0x0002), \
	American Power Conversion(0x051d), rev 0.06


Looking into source I found that prototyping:

-----8<-----[ /usr/src/lib/libusbhid/libusbhid.h ]-----8<-----
[...]
int hid_report_size(report_desc_t d, unsigned int id, enum hid_kind k);
[...]

is different from man page (2nd/3rd parameter swapped):
-----8<-----[ man hid_report_size ]-----8<-----
[...]
    int
    hid_report_size(report_desc_t d, unsigned int id, hid_kind_t k);
[...]

I think man page is wrong, but this is not a problem.

After playing with usbhidctl I found that my APC use 0xff84, 0xff85 and
0xff86 instead of 0x84, 0x85 and 0x86 as it would so I created a custom
file with the contents of /usr/share/misc/usb_hid_usage and with a copy
of pages 132/133 to 0xff84/0xff85 and now it decode pages/usages.

Now I'm at a dead end, usbhidctl say:
	device does not support immediate mode, only changes reported.
but interrogating device with -a and/or -l show me only zeros.

If you need my config/boot.log feel free to download them from:
	ftp://ftp.torrini.org/pub/FreeBSD/APC-hacking/

What else can I do (apart from changing UPS)?

I hope you can point me to the right direction (docs or ML)...

TIA

PS: can you change .../usb_hid_usage and use hex notation, instead of
    decimal one, also for pages because usbhidctl report them as hex?
