2008-04-24USB: ehci tolerates some buggy devicesDavid Brownell
This teaches EHCI how to to work around bugs in certain high speed devices, by accomodating "bulk" packets that exceed the 512 byte constant value required by the USB 2.0 specification. (Have a look at section 5.8.3, paragraphs 1 and 3.) It also makes the descriptor parsing code warn when it encounters such bugs. (We've had reports of maybe two or three such devices, all pretty recent.) Such devices are nonconformant. The proper fix is have the vendors of those devices do the simple, obvious, and correct thing ... which will let them be used with USB hosts that don't have workarounds for this particular vendor bug. But unless/until they do, we can at least have one of the high speed HCDs work with such buggy devices.

If called and the device is not authorized to be used, then we don't allow reading the configurations. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-12USB: add IAD support to usbfs and sysfsCraig W. Nadler
USB_IAD: Adds support for USB Interface Association Descriptors. This patch adds support to the USB host stack for parsing, storing, and displaying Interface Association Descriptors. In /proc/bus/usb/devices lines starting with A: show the fields in an IAD. In sysfs if an interface on a USB device is referenced by an IAD the following files will be added to the sysfs directory for that interface: iad_bFirstInterface, iad_bInterfaceCount, iad_bFunctionClass, and iad_bFunctionSubClass, iad_bFunctionProtocol Signed-off-by: Craig W.

2007-07-12USB: Fix up full-speed bInterval values in high-speed interrupt descriptorLaurent Pinchart
Many device manufacturers are using full-speed bInterval values in high-speed interrupt endpoint descriptors. If the bInterval value is greater than 16, assume the device uses full-speed descriptors and fix the value accordingly.

2007-07-12USB: Handle bogus low-speed Bulk endpointsAlan Stern
A noticeable number of low-speed devices mistakenly include descriptors for Bulk endpoints, which is forbidden by the USB spec. In an attempt to make such devices more usable, this patch (as924) converts the descriptors to Interrupt with an interval of 1 ms.

2007-06-08USB: Fix up bogus bInterval values in endpoint descriptorsAlan Stern
This patch (as904) adds code to check for endpoint descriptor bInterval values outside the legal limits. Illegal values are set to 32 ms, which seems like a reasonable default. This fixes Bugzilla #8432. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-05-22USB: don't try to kzalloc 0 bytesAlan Stern
This patch (as907) prevents us from trying to allocate 0 bytes when an interface has no endpoint descriptors. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Change usb_get_configuration() so that it is more tolerant to devices with bad configuration descriptors (it'll make it ignore configurations that fail to load). Signed-off-by: Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2005-11-17[PATCH] USB: move CONFIG_USB_DEBUG checks into the MakefileGreg Kroah-Hartman
This lets us remove a lot of code in the drivers that were all checking the same thing. It also found some bugs in a few of the drivers, which has been fixed up. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-28[PATCH] usbcore: Fix handling of sysfs strings and other attributesAlan Stern
This patch (as592) makes a few small improvements to the way device strings are handled, and it fixes some bugs in a couple of other sysfs attribute routines. (Look at show_configuration_string() to see what I mean.) Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

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!
