When an ISOCHRONOUS URB was captured the packet-usb.c does not handle it.
Case URB_ISOCHRONOUS was added at two different places to handle it also.

- if offset is 0, tvb_length is the same as tvb_length_remaining, just faster.
Replace
- col_append_fstr() with faster col_append_str()
- col_add_str() with col_set_str()
when it's safe

add defines for data direction (which direction in/out is data being transferred for this particylar request/response pair)
and a mask for which bits of the byte contains the type.

This patch enables packet-usb.c to display all descriptors in the GET
CONFIGURATION request, regardless of whether we know how to decode
them. (All descriptors in that request share the same first two
bytes.)
It also adds the HID descriptor type (not the report descriptor,
though - that is buried in a class request, not a device request). I
am still working on actually decoding this descriptor.

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.

Modified to support the header as a pseudo_header rather than as part of
the packet data.
Fixed some calls that fetch data from the USB packet to fetch it in
little-endian byte order.
Got rid of redundant code to get conversation-specific data (the
get_usb_conv_info() call already does that).
For control packets, only parse the setup information if setup_flag is
0.
Don't interpret a control packet as a standard request unless the setup
type is "Standard".

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
svn path=/trunk/; revision=19589
add tracking so that when we find an interface descriptor which tells us the device class we also create a conversation for each and every endpoint for that interface and also let all conversations (one for each endpoint) share the same usb conversation info structure.
store the device type inside this conv_info structure
add the required code to manage BULK data pdus and have it for now only display what kind of bulk data is contained (interface class as snooped from the descriptors)
we now only need a class dissector table we can fork off into from the bulk dissector in usb and then an external usb_masstorage dissector that registers itself as a mass storage device and we should be all set to dissect the scsi layer being transported atop usb
svn path=/trunk/; revision=19575
ansp provide the desired port/endpoints in the call to get/create a conversation so that we later when we see the a descriptor that says Endpoint X is using class Y
we need tis to register that certain endpoints are used for mass storage
(or other applications)
svn path=/trunk/; revision=19573
start introducing conversations to the usb dissector so that we can start tracking requests/responses
which we need to in order to dissect for example the data returned by a device to a GET DESCRIPTORS call
svn path=/trunk/; revision=19539
The attached patch fix parsing of the setup header in the usb dissector.
Currently the size of the field specified into proto_tree_add_item call
was wrong.
