[Nut-upsuser] RE: Nut-upsuser Digest, Vol 11, Issue 3

[Nevil Thatcher]

Hi Vladimir,

I have got 2.0.3 working on netBSD 3.0.

To get it operational I needed to do the following (most of this is from
memory...).

1).
Recompile kernel with uhid removed. If uhid ataches to the device then
libusb is not able to. Have to allow generic usb driver ugen to claim port.


>From dmesg

usb0 at uhci0: USB revision 1.0
uhub0 at usb0
uhub0: VIA Technologies UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered

ugen0 at uhub0 port 1
ugen0: MGE UPS SYSTEMS NOVA AVR, rev 1.10/0.01, addr 2

2).

Install libusb 0.1.12

0.1.11 includes a bug fix for *BSD to allow short reads. Without this
various status is not returned from UPS.

3). I found another problem with libusb on netBSD in that the 

Function usb_interrupt_read() calls read() which blocks on read from usb
until buffer is full. In my case this was seemingly infinite. A timeout is
passed to the function but netBSD does not seem to respect this.

I have been meaning to lodge a bug-report but haven't as yet.

To fix (hack) I changed bsd.c in libusb as follows:

Change 
Fd = ensure_ep_open(dev, ep, 0, O_RDONLY)

To

Fd = ensure_ep_open(dev, ep, 0, O_RDONLY | O_NONBLOCK)

This just tells the read to return immediately if no data from usb rather
than block. OS buffers device anyway.

With this plus the information in the faqs I was able to achieve an
operational system.

Hope this is someway helps.
