NEC usb controller and huawei E620 support

[Maxim Belooussov]

Hi all,

I have a small question, but it's not tech enough for tech@, so asking it here.

How do I add support for NEC usb controller to OpenBSD?

http://www.huawei.com/mobileweb/en/products/view.do?id=145

Currently it looks like the NEC usb controller is not recognized
because OpenBSD doesn't know its id. Huawei card is 'hiding' behind
the controller, and is not visible at the moment.

I've taken a look at /usr/src/sys/dev/usb/usbdevs file and saw this:

/* NEC products */
product NEC USB2EXTEND          0x0409  Repeater
product NEC HUB                 0x55aa  hub
product NEC HUB_B               0x55ab  hub
product NEC PICTY760            0xbef4  Picty760
product NEC PICTY900            0xefbe  Picty900
product NEC PICTY920            0xf0be  Picty920
product NEC PICTY800            0xf1be  Picty800

According to my dmesg (below), device id is:
ohci0 at cardbus0 dev 0 function 0 "NEC USB" rev 0x43: irq 5, version 0.0
ohci0: unsupported OHCI revision
ohci1 at cardbus0 dev 0 function 1 "NEC USB" rev 0x43: irq 5, version 0.0
ohci1: unsupported OHCI revision

But I cannot figure out what string should I add to usbdevs file:

product NEC PCMCIAUSB      0x4300

or

product NEC PCMCIAUSB      0x3433 (43 into hex??)

or something completely different?

I've tried searching the net, but not enough definite pointers there neither.

you can get the id from pcidump -v, something like this:

0:0:0: Intel 82Q965 Host
  0x0000: Vendor ID: 8086 Product ID: 2990

Hi all,

Thanks to all who have responded.

Replying for the archives.

> the controller, and is not visible at the moment.

After finding the id with `pcidev -dv` and adding it to usbdevs didn't
do the trick. The problem seems to be hiding in
/usr/src/sys/dev/usb/ohci.c file:

        if (OHCI_REV_HI(rev) != 1 || OHCI_REV_LO(rev) != 0) {
                printf("%s: unsupported OHCI revision\n",
                       sc->sc_bus.bdev.dv_xname);
                sc->sc_bus.usbrev = USBREV_UNKNOWN;
                return (USBD_INVAL);
        }

The device seems to report wrong (unsupported) ohci revision.
Intentionally messing up the revision check in the source code and
recompiling the kernel results in:

ohci0 at cardbus0 dev 0 function 0 "NEC USB" rev 0x43: irq 5, version 0.0
ohci0: reset timeout
ohci0: init failed, error=13
ohci1 at cardbus0 dev 0 function 1 "NEC USB" rev 0x43: irq 5, version 0.0
ohci1: reset timeout
ohci1: init failed, error=13

Hence, just adding device and vendor id and recompiling the kernel is
not enough, ohci handling code needs to support the "correct" revision
for the device. Or tweaking usb-quirks as Miod does from time to time,
but this is way beyond my current level.

the usb controller is detected just fine.

that is your real problem.

Indeed, and that's exactly what I said in my previous email on June
20th. Thank you for confirming my diagnosis :)

Once I get my new laptop from my work, I intend to lend the card to
Felix, so maybe he can help.

There might be multiple problems. Does that cardbus slot work
correctly with other 32-bit devices?

Had to dig out some PCMCIA network cards from the garbage bin - those
got recognized.

These commits caught my attention the other day:

http://marc.info/?l=openbsd-cvs&m=121501156320436&w=2

And after new kernel recompile and reboot the card shows up in dmesg:
