The documentation for usbmon in the kernel 2.6.31-rc7 kernel doesn't match what the kernel exposes in the debug fs tree. This patch fixes it.

2009-09-23USB: usbmon: touch up the documentationPete Zaitcev
I think this sentence was confusing regarding the possible size of the data area. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-03-24USB: usbmon: Add binary API v1Pete Zaitcev
This patch adds an extension to the binary API so it reaches parity with existing text API (so-called "1u"). The extension delivers additional data, such as ISO descriptors and the interrupt interval. Signed-Off-By: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-12-17usbmon: drop bogus 0t from usbmon.txtPete Zaitcev
The example is incorrect: there is no 0t socket (the '1t' format has no bus number in it). Also, correct the broken sentence for USB Tag. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-10-12USB: usbmon doc update - mention new wildcard ('0') busPaolo 'Blaisorblade' Giarrusso
Update usbmon documentation, mentioning the "zero" (wildcard) bus. Possibly, in my first hunk, the 'either ... or ...' should be rephrased a bit to be expressed better.

2007-04-27usbmon: Extended text APIPete Zaitcev
This patch adds a new text API, codenamed '1u', which captures more URB fields than old '1t' interface did. Also the '1u' text API is compatible with the future "bus zero" extension.

2007-02-07USB: add binary API to usbmonPete Zaitcev
This patch adds a new, "binary" API in addition to the old, text API usbmon had before. The new API allows for less CPU use, and it allows to capture all data from a packet where old API only captured 32 bytes at most. There are some limitations and conditions to this, e.g. in case someone constructs a URB with 1GB of data, it's not likely to be captured, because even the huge buffers of the new reader are finite. Nonetheless, I expect this new capability to capture all data for all real life scenarios. The downside is, a special user mode application is required where cat(1) worked before. I have sample code at http://people.redhat.com/zaitcev/linux/ and Paolo Abeni is working on patching libpcap. This patch was initially written by Paolo and later I tweaked it, and we had a little back-and-forth. So this is a jointly authored patch, but I am submitting this I am responsible for the bugs.

2006-06-21[PATCH] USB: update usbmon.txtPete Zaitcev
Fix up the documentation. Apparently, I left unedited copy-paste results in examples. Also, Alan helped me to improve the most confusing parts. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-08-04[PATCH] USB: ub documentation updatePete Zaitcev
The patch which went in was correct, but not quite what I had in mind. Here is a patch to update that a little bit. Original patch is at: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4749f32da939d4e4160541b2cadc22492bb507ec Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-07-12[PATCH] USB: Patch to make usbmon to print control setup packetsPete Zaitcev
Make usbmon to print Setup packets of Control transfers. This is useful when debugging enumeration issues. This is a change to the trace format which is not fully compatible. A parser has to look at the data length word now. If that word is a character like 's', read setup packet before proceeding with data. I decided not to bump the API tag for this because not many such parsers exist at this point. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
