option driver, ZTE MF_330 matches linux usb 2.0 root hub
Michael Tokarev
loading option.ko driver even if I've no single
GSM modem anywhere around.
After some investigation I found this in option.c:
/* ZTE PRODUCTS -- alternate vendor ID */
#define ZTE_VENDOR_ID2 0x1d6b
#define ZTE_PRODUCT_MF_330 0x0002
..
{ USB_DEVICE(ZTE_VENDOR_ID2, ZTE_PRODUCT_MF_330) },
But this matches... "Linux Foundation 2.0 root hub",
which has this module alias:
usb:v1D6Bp0002d0206dc09dsc00dp00ic09isc00ip00
What are options to fix this option now? :)
Thanks!

Forgot to mention, and to add proper Cc. The commit
is this one:

USB: option: add ID for ZTE MF 330
Based on the information provided for by Paweł Drobek, add
a second vendor ID and the correct product ID for ZTE MF 330.

Are the IDs really correct? Maybe it's just a typo
after all...
It is interesting that no one noticed this so far.
Or it's just because it's difficult to search for -
"option" is really a bad search term ;)

I don't know, Paweł, can you provide the output of 'lsusb -v' for your
system where you saw this being a option device instead of a hub?
thanks,

Can you please provide the information Greg asked?

Namely, `lsusb -v' output from the system when this
modem is inserted.
At least, maybe this device ID should be restricted to
the particular class of devices. Alternatively, if number
of such devices on the marked is small (google wasn't able
to find any other references), it should be easy to control
it using a custom udev rule that loads `option' driver and
forcibly binds it to this device. That is, by the way, an
alternative solution to make it work.
But it is curious that ZTE used "wrong" vendor class for
its product.
Thanks!

Which PCMCIA card? The device at question is USB, not PCMCIA,
that's why we requested lsusb.
Has anyone else seen this device? For some reason I doubt
it has the indicated USB ID...
Thanks,

So, what's our course of actions now?
I'd suggest to revert this change and deal with this device
again (specifying the device IDs more precisely, like,
including the device class or what it is called in USB
world) when someone will have it for real.

Paweł, are there any news on this?

Hi guys
In attachment is a file with "lsusb -v" output, please check it. if you
need something more feel free to tell me about it

So, as far as I can see, this is covered by
#define ZTE_VENDOR_ID 0x19d2
#define ZTE_PRODUCT_MF622 0x0001
{ USB_DEVICE_AND_INTERFACE_INFO(ZTE_VENDOR_ID, ZTE_PRODUCT_MF622, 0xff, 0xff, 0xff) }, /* ZTE WCDMA products */
and it should Just Work aftere reverting a559d2c8c1bf652ea2d0ecd6ab4a250fcdb37db8
"USB: option: add ID for ZTE MF 330". But I'm not sure this really
is MF330, since the device ID says it's MF622.
Are we talking about the same device?
Besides, why in linux it's identified as ZTE, while
lsusb lists it as "ONDA Comm." ?
Thanks,

ONDA and ZTE are usually the very same chip.
Also please note that USB ID of these devices usually changes after
'usb_modeswtich' triggers in userspace (and many distros ship udev rule
for this as a default nowadays), which might contribute to the overall
confusion a little bit more.
