2007-02-07EHCI: force high-speed devices to run at full speedAlan Stern
This patch (as710) adds a sysfs class-device attribute file named "companion" for EHCI controllers. The file contains a list of port numbers that are dedicated to the companion controller; by writing a port number to the file the user can force a high-speed device attached directly to the computer to run at full speed. (As far as I know it is not possible to do this for a device attached to an external hub.) A port is removed from the file by writing the negative of its port number. Several users have asked for this facility and it seems like a useful thing to have. Every now and then one runs across a device which behaves much better at full speed than at high speed.

2007-02-07EHCI: don't hide ports owned by the companionAlan Stern
This patch (as709) changes the way ehci-hcd presents port status values for ports owned by the companion controller. It no longer hides the information; in particular, it allows the core to see the disconnect event that occurs when a full- or low-speed device is switched over to the companion. This is required for the next patch in this series.

2007-02-07EHCI: local variable for port status registerAlan Stern

2007-02-07usbcore: remove unused bandwith-related codeAlan Stern
This patch (as841) removes from usbcore a couple of support routines meant to help with bandwidth allocation. With the changes to uhci-hcd in the previous patch, these routines are no longer used anywhere. Also removed is the CONFIG_USB_BANDWIDTH option; it no longer does anything and is no longer needed since the HCDs now handle bandwidth issues correctly.

2007-02-07usb-storage: SCSI level fixesAlan Stern
This patch (as835) removes from usb-storage the code which sets all devices to a SCSI level of at least SCSI-2. The original reasons for doing this no longer apply, and in fact it prevents certain kinds of ATA pass-thru commands from being used. The patch also marks CB and CBI devices that are SCSI-0 (legacy SCSI) as being single-LUN, since the combined SCSI-over-USB transport protocol has no way to convey LUN information to these devices.

The number of entries displayed is limited to 10, and the driver now checks for the correct Skeleton QH link value at the end of each chain of Isochronous TDs.

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.

This case is quite common in embedded system where you want to handle both the integrated ohci controller and some extra controller on PCI.

2007-02-07rndis_host learns ActiveSync basicsOle Andre Vadla Ravnas
Windows Mobile 5 based devices described as supporting "ActiveSync": - Speak RNDIS but lack the CDC and union descriptors. This patch updates the cdc ethernet code to fake ACM descriptors we need. - Require RNDIS_MSG_QUERY messages to include a buffer of the size the response should generate. This patch updates the rndis host code to pass this will-be-ignored data. The resulting RNDIS host code has been reported to work with several WM5 based devices. (Note that a fancier patch is available at synce.sf.net.) Some bugfixes, affecting not just ActiveSync: (a) when cleaning up after RNDS init fails, scrub the second interface just like cdc_ether does, so disconnect won't oops. (b) handle peripherals that use the pad-to-end-of-packet option; some devices can't talk to us if that option doesn't work. (c) when choosing configurations, don't forget about an RNDIS config just because the RNDIS driver is dynamically linked. Cleanup, streamlining, bugfixes, Kconfig, and matching hub driver update. Also for paranoia's sake, refuse to talk to something that looks like a real modem instead of RNDIS.

2007-02-07USB: ethernet gadget interop with MCCI Windows driverDavid Brownell
It turns out that minor tweaks to the "CDC Subset" support in the Ethernet gadget driver, just updating a config descriptor, let it be automagically recognized by a Windows driver supported by MCCI. This patch adds those descriptors, so systems using PXA 255 processors (like Gumstix etc) can interop with those commercial MS-Windows drivers. This is a Good Thing since Microsoft's RNDIS code has bugginess issues, which are unfortunately compounded by "won't fix" issues as well as "the published specs are incomplete and wrong" issues. Being able to talk to the MCCI driver gives Windows users another connectivity option. (MCCI also has CDC Ethernet drivers, which can help most non-PXA processors.)

Hopefully this will make it more maintainable and less error prone. Code makes use of search_exception_tables(). Since it calls this function before the kernel exeception table is sorted, there is an early call to sort_main_extable().
