In this patch, we want to do one thing: add more Huawei product IDs into the USB driver. Then it can support more Huawei data card devices. So to declare the unusual device for new Huawei data card devices in unusual_devs.h and to declare more new product IDs in option.c. To modify the data value and length in the function of usb_stor_huawei_e220_init in initializers.c That's because based on the USB standard, while sending SET_FETURE_D to the device, it requires the corresponding data to be zero, and its sending length also must be zero. In our old solution, it can be compatible with our WCDMA data card devices, but can not support our CDMA data card devices. But in this new solution, it can be compatible with all of our data card devices.

/* Special Initializers for certain USB Mass Storage devices
|
|
*
|
|
* Current development and maintenance by:
|
|
* (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
|
|
*
|
|
* This driver is based on the 'USB Mass Storage Class' document. This
|
|
* describes in detail the protocol used to communicate with such
|
|
* devices. Clearly, the designers had SCSI and ATAPI commands in
|
|
* mind when they created this document. The commands are all very
|
|
* similar to commands in the SCSI-II and ATAPI specifications.
|
|
*
|
|
* It is important to note that in a number of cases this class
|
|
* exhibits class-specific exemptions from the USB specification.
|
|
* Notably the usage of NAK, STALL and ACK differs from the norm, in
|
|
* that they are used to communicate wait, failed and OK on commands.
|
|
*
|
|
* Also, for certain devices, the interrupt endpoint is used to convey
|
|
* status of a command.
|
|
*
|
|
* Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
|
|
* information about this driver.
