Description M. Warner Losh 2009-01-02 19:30:04 UTC
My externeal usb DVD drive is showing up as 'da' rather than as 'cd'
when using usb2_storage_mass.  When I load usb2_storage_ata it shows
up as a 'cd' device that's usable.  mass should behave as well as ata
in this case, or it should detect that it can't get it right and
refuse to attach things.

Fix: 

Unknown.
How-To-Repeat: 
I loaded all the usb2 drivers at runtime:

kldload usb2_controller_{e,o}hci
kldload usb2_sotrage_mass

I then plugged in the drive.  This is an external DVD drive.

Maybe the AutoInstall CD detecter is interfering with your device.

Can you use "usbconfig" to dump the device and config descriptors of your CD 
device?

You can also try:

kldload usb2_quirk
usbconfig add_dev_quirk_vplh <vid> <pid> <lo_rev> <hi_rev> UQ_CFG_INDEX_0

Hmmm...

: device?

How?

: You can also try:
: 
: kldload usb2_quirk
: usbconfig add_dev_quirk_vplh <vid> <pid> <lo_rev> <hi_rev> UQ_CFG_INDEX_0

What the heck are these different fields?  vid, pid, etc?

Run "usbconfig -h".

usbconfig -u xxx -a yyy dump_curr_config_desc
usbconfig -u xxx -a yyy dump_device_desc

Vendor ID, product ID, lower inclusive revision number, higher inclusive 
revision numer that is used when matching the quirk.

Comment 4 M. Warner Losh 2009-01-03 19:29:38 UTC
: Run "usbconfig -h".

That doesn't tell me enough to know what you need to diagnose this
problem.

: usbconfig -u xxx -a yyy dump_curr_config_desc
: usbconfig -u xxx -a yyy dump_device_desc

How do I know the address?  Is it the .Y in ugenX.Y?

If so, here's what you requested:

I'll give it a try...

> How do I know the address?  Is it the .Y in ugenX.Y?

Yes.

> If so, here's what you requested:

I see that your CD-rom device is quirked to the wrong subclass (SCSI) in 
usb2/storage/umass2.c:

#define UISUBCLASS_SFF8070I     5
#define UISUBCLASS_SCSI         6
       bInterfaceSubClass = 0x0005 

#define UIPROTO_MASS_BBB_OLD    2       /* Not in the spec anymore */
#define UIPROTO_MASS_BBB        80      /* 'P' for the Iomega Zip drive */
       bInterfaceProtocol = 0x0050

Solution:

Try removing or limiting the following quirk:

        {USB_VENDOR_MYSON, USB_PRODUCT_MYSON_HEDEN, RID_WILDCARD,
                UMASS_PROTO_SCSI | UMASS_PROTO_BBB,
                NO_INQUIRY | IGNORE_RESIDUE
        },

I think this issue might be fixed in -current now, as of today.

Please give it a spin.
