This patch (as693b) makes the usbtest driver report errors in the isochronous bulk transfer tests instead of always returning 0. As an arbitrary cutoff, an error is returned if more than 10% of the packet transfers fail. It also stops a test immediately upon receiving an URB submission error. For a test harness, it's especially important to report when errors occur! Signed-off-by:

By the way I have to ask you to add new (vid,pid) pair to cp2101 driver. This device is argussoft's avr in-system programmer AS3M, http://atmel.argussoft.ru/hard.htm it's based on cp2101 chip and works pretty well with the linux driver. It could be used with argussoft's `asisp1109.exe' (http://atmel.argussoft.ru/download/software/as-tools.soft/asisp.zip) tool run under wine. Signed-off-by:

ctrl_complete functions acquires ctx->lock and tries to unlink all queued urbs in case of errors through usb_unlink_urb func. In its turn usb_unlink_urb calls, through the hcd driver, usb_hcd_giveback_urb which calls ctrl_complete again. At this time, ctx->lock is already taken by the same function. Signed-off-by:

This patch (as690) does the same thing for ISO TDs as as680 did for non-ISO TDs: free them as they are used rather than all at once when an URB is complete. At the same time it fixes a minor buglet (I'm not aware of it ever affecting anyone): An ISO TD should be retired when its frame is over, regardless of whether or not the hardware has marked it inactive.

This patch (as689) stores the period for periodic transfers (interrupt and ISO) in the queue header. This is necessary for proper bandwidth tracking (not yet implemented). It also makes the scheduling of ISO transfers a bit more rigorous, with checks for out-of-bounds frame numbers. Signed-off-by:

This patch (as688) fixes a small race in uhci-hcd. Because ISO queues aren't controlled by queue headers, they can't be unlinked. Only individual URBs can. So whenever multiple ISO URBs are dequeued, it's necessary to make sure the hardware is done with each one. We can't assume that dequeuing the first URB will suffice to unlink the entire queue.

This patch (as687) changes uhci-hcd to keep track of frame numbers as full-sized integers rather than 11-bit values. This makes them a lot easier to handle and makes it possible to schedule beyond a 2-second window, should anyone ever want to do so. Signed-off-by:

This patch increases an arbitrary limit on the size of individual isochronous packets submitted via usbfs. The limit is still arbitrary, but it's now large enough to support the maximum packet size used by high-bandwidth isochronous transfers. Signed-off-by:

This patch removes the artificial 4088-byte limit that usbfs currently places on Control transfers. The USB spec does not specify a strict limit on the size of an entire control transfer. It does, however, state that the data stage "follows the same protocol rules as bulk transfers." (USB 2, 8.5.3) The level of support for large control transfers in real host controllers varies, but it's important to support at least 4K transfers. Windows enforces a maximum control transfer size of 4K, so there exists some hardware that requires a full 4096 byte data stage. Without this patch, we fall short of that by 8 bytes on architectures with a 4K page size, and it becomes impossible to support such hardware with a user-space driver. Since any limit placed on control transfers by usbfs would be arbitrary, this patch replaces the PAGE_SIZE limit with the same arbitrary limit used by bulk transfers. Signed-off-by:

The swsusp.txt documentation harshes confusingly on USB, and this patch addresses the issue. It's harsh because it blames USB for some issues that are generic to all drivers -- especially those supporting removable media -- and it's confusing since it says that USB has the issue with "suspend" not just swsusp ... while in reality, USB doesn't have the issue when real system suspend states are used.

Some old Intel UHCI controllers have a bug that has shown up in a few systems (the PIIX3 "Neptune" chip set). Until now there has not been any simple way to work around the bug, but the lastest changes in uhci-hcd have made it easy. This patch (as684) adds the work-around. Signed-off-by:

This patch (as683) re-implements Full-Speed Bandwidth Reclamation (FSBR) properly. It keeps track of which endpoint queues have advanced, and when none have advanced for a sufficiently long time, FSBR is turned off. The next TD on each of the non-moving queues is modified to generate an interrupt on completion, so that FSBR can be re-enabled as soon as the hardware starts to make some progress. Signed-off-by:

This patch (as682) gets rid of the TD-removal list in uhci-hcd. It is no longer needed because now TDs are not freed until we know the hardware isn't using them. It also simplifies the code for adding and removing TDs to/from URBs. Signed-off-by:

This patch (as680) frees non-isochronous TDs as they are used, rather than all at once when an URB is complete. Although not a terribly important change in itself, it opens the door to a later enhancement that will reduce storage requirements by allocating only a limited number of TDs at any time for each endpoint queue.

This patch (as679) combines the result routine for Control URBs with the routine for Bulk/Interrupt URBs. Along the way I eliminated the debugging printouts for Control transfers unless the debugging level is set higher than 1. I also eliminated a long-unused (#ifdef'ed-out) section that works around some buggy old APC BackUPS devices. Signed-off-by:

It seems to be relatively common for USB keyboards and mice to dislike being polled for reports. Since there's no need to poll a keyboard or a mouse, this patch (as685) automatically sets the HID_QUIRK_NOGET flag for devices that advertise themselves as either sort of device with boot protocol support. This won't cure all the problems since some devices don't support the boot protocol, but it's simple and easy and it should fix quite a few problems. Signed-off-by:

[PATCH] USB HID/HIDBP, INPUT DRIVERS: fix various usb/input/hid-input.c bugs that make Apple Mighty Mouse work poorly Transposed lines of code in drivers/usb/input/hid-input.c causes the capability bits for a new HID device to be set before quirks are applied at configuration time. When an HID event is then sent up to the input layer, it may then be discarded as irrelevant because the wrong capability bit is set. Further, the quirks for the Apple Mighty Mouse are not quite right: the horizontal scrolling needs its axis reversed, and the left and center buttons are transposed. Also, the mouse is labeled in the kernel with its earlier name (I think) of Apple PowerMouse. Steps to reproduce problem: Plug in an Apple Mighty Mouse. Note that horizontal scrolling doesn't work at all, and in fact doesn't generate any input events on /dev/input/eventN. Note also that pushing the middle button performs the right button action, and vice versa. Once you have the horizontal scrolling working, note that it is backward WRT both to vertical scrolling and to common sense. This patch maybe should be broken up, as it does address two problems. The transposed code in hidinput_configure_usage() probably creates bugs beyond just the Mighty Mouse. The rest of the patch renames POWERMOUSE to MIGHTYMOUSE everywhere (which I *believe* is correct), fixes the MIGHTYMOUSE quirk to swap the center and right mouse buttons, and adds a new quirk HID_QUIRK_INVERT_HWHEEL also assigned to the MIGHTYMOUSE with code in hidinput_hid_event() to implement it.

This patch (as676) fixes a small bug in uhci-hcd's enqueue routine. When an URB is unlinked or gets an error and the completion handler queues another URB for the same endpoint, the queue shouldn't be allowed to start up again until the handler returns. Not even if the new URB is the only one on its queue. Signed-off-by:

After some further testing with my flash device I realised that our current probe doesn't always work (e.g. when no media is inserted). Now that Peter Chubb's patch has simplified the detection of 99% of the HP CD writers out there, we have a much smaller range of hardware to work with on the shared device ID, so it should be possible to try some of the previous probe options again: we just need to find another tester with a USBAT2-based HP CD writer. This patch hardcodes the flash detection until someone comes along with one of these obscure CD drives. Note that these devices are extremely rare, so even if we can't ever find a decent probe method, at least we will be supporting almost all of the USBAT-based hardware out there. Signed-off-by:

I've worked out what's going wrong. The scsi layer is now much more likely to pass down scatterlists instead of plain buffers. So you have to make sure that they're handled correctly. In one of the changes along the way, usbat_write_block and friends stopped obeying the srb->use_sg flag. Anyway, with the appended patch, and the one I'm putting in the next email, it all seems to work for the HP cd4e. Of course, someone's going to have to test it with the flash drives as well.... This patch teaches the usbat_{read,write}_block functions to obey the use_sg flag in the scsi-request. Signed-off-by: -

Some hubs claim not to support port-power switching, and right now the hub driver believes them and does not enable power to their ports. However it turns out that even though they don't actually switch power, they do ignore all events on a port until told to turn on the power! This problem has been reported by several users. This revised patch (as672b) makes the hub driver always try to turn on port power to all hubs, regardless of what the hub descriptor says. It also adds a comment explaining the need for this.
