Centralize logic related to per-interface conversations, and expose it for use
by class-specific dissectors.
Class-specific descriptor dissectors also need to know the interface in whose
context they are called to work.
This is a prerequisite for a USB Video Class dissector, which needs to decode
many class-specific descriptors.

Improve handling of truncated USB Configuration descriptors.
In contrast to other descriptor types, configuration descriptors have varying
lengths and may be quite long. This makes them much more prone to truncation
by a host that is cautious about reading large descriptors.
A real-world case has arisen where a host requests a partial configuration
descriptor of a USB webcam, and wireshark improperly reports that the response
is malformed.
Change configuration descriptor dissection to distinguish between truncation
induced by the host, which is not an error, and descriptor truncation or
reporting of invalid descriptor lengths by the device, which are.
This patch also relieves class-specific dissectors of the burden of checking
that the descriptor length and type fields are available, and that all the
bytes claimed by the descriptor length are also available.

USB: Add support for vendor_id/product_id,
bus_id/device_address and class/subclass/protocol
tables
USB subdissectors can be decoded by class/subclass/protocol. If fail try vendor_id/product_id.
bus_id/device_address is intented to use by DecodeBy, so user can decode specified device as need.

Conversation address generation during processing of endpoint descriptors
is not being done in a manner consistent with that of general USB
packet dissection. I am not aware of any observable manifestation of this
bug.
svn path=/trunk/; revision=41634
Support PPP-over-USB.
Don't remove the USB pseudo-header from the packet data for
Linux USB packets, just byte-swap it if necessary and have the
USB dissector fetch the pseudo-header from the raw packet data.
Update USB language ID values.

change the private data pointer name from masstorage to class_data
since there will be future class specific dissectors that will also want to hang
some extra data off these structures

It is suboptimal to have the endpoint both being the "port" and also 4 bytes out of the address.
But it looks better to have addresses as <device>.<endpoint> .

since dlt189 was introduced the dissector has been suboptimal
assuming the capture usb_memory_stick.pcap on the wiki shows what this linktype
should look like, this patch
- adds request in/response in/time generated fields to the dissect pane
- fixes the tracking of what is a request and what is a response (the old code just can not have worked!)
- fixes conversation tracking to work (dont add the port/endpoint into the length of the address)
- handles some mysterious extra 8 bytes prepended to a lot of different packets.

implement class specific control commands : reset and getmaxlun for mass storage
now with a better understanding of the problem space for usb and device classes we can start cleaning the code up and make it nice
svn path=/trunk/; revision=19659
this is a wrapper protocol to store SCSI frames inside usb bulk data transfers
the dissector is far from complete but does
track ITL and ITLQ structures and will also call the SCSI dissector to
dissect the SCSI CDB.
what is still missing is handling of data in/out and scsi responses
at least it will now display the SCSI CDB and dissect it. woohoo
