Mr. Kevin and everyone,
There was a serious mistake in the previous message. I forgot to
attach the patch. Please ignore it. I am posting it again.
I was never reported for that product id 0x0132. Yet you can continue
support for it if it is rare. In the meantime, we can add more devices
to the header and add those names to "usb_device_id" table in
"InterfaceInit.c". I added a new product string
"BCM_USB_PRODUCT_ID_ZTE_326" and also modified the device id table.
Again, I removed product if 0xbccd because Beceem, ZTE, Sprint use
this id for the block device containing device driver. Again, this is
always switched to base product id via udev. Here is my dmesg output
when udev is turned off.
=====
root@inspiron:~# dmesg -c

=====
I did build after these changes and probed the module. It works
perfectly. I also tested 0x0172 and 0x0173. No error is reported. So I
assure that these products are valid. Not sure about 0x0132. Here is
the modinfo output.

To use the patch, remove module if it is probed. Build, and then probe.
About the TODO: I currently have a solution to make the device work.
It is not from Intel's wimax stack. I used Beceem's API. Can we
discuss on this?
Please let me know any feedback you have on this patch or the approach used.
Thanks,
