This reverts commit 806e8f8f. To quote Alan Stern: The necessity for this patch has been under discussion. It turns out the UDC that Mian has been working on and Felipe's UDC have contradictory requirements. Mian's UDC driver wants a bulk-OUT transfer length to be shorter than the maxpacket size if a short packet is expected, whereas Felipe's UDC hardware always needs bulk-OUT transfer lengths to be evenly divisible by the maxpacket size. Mian has agreed to go back over the driver to resolve this conflict. This means we probably will not want this patch after all. (In fact, we may ultimately decide to change the gadget framework to require that bulk-OUT transfer lengths _always_ be divisible by the maxpacket size -- only the g_file_storage and g_mass_storage gadgets would need to be changed.)

A Synopsys USB core used in various SoCs has a bug which might cause that the host controller not issuing ping. When software uses the Doorbell mechanism to remove queue heads, the host controller still has references to the removed queue head even after indicating an Interrupt on Async Advance. This happens if the last executed queue head's Next Link queue head is removed. Consequences of the defect: The Host controller fetches the removed queue head, using memory that would otherwise be deallocated.This results in incorrect transactions on both the USB and system memory. This may result in undefined behavior. Workarounds: 1) If no queue head is active (no Status field's Active bit is set) after removing the queue heads, the software can write one of the valid queue head addresses to the ASYNCLISTADDR register and deallocate the removed queue head's memory after 2 microframes. If one or more of the queue heads is active (the Active bit is set in the Status field) after removing the queue heads, the software can delay memory deallocation after time X, where X is the time required for the Host Controller to go through all the queue heads once. X varies with the number of queue heads and the time required to process periodic transactions: if more periodic transactions must be performed, the Host Controller has less time to process asynchronous transaction processing. 2) Do not use the Doorbell mechanism to remove the queue heads. Disable the Asynchronous Schedule Enable bit instead. The bug has been discussed on the linux-usb-devel mailing-list four years ago, the original thread can be found here: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg45345.html This patch implements the first workaround as suggested by David Brownell. The built-in USB host controller of the Atheros AR7130/AR7141/AR7161 SoCs requires this to work properly. Signed-off-by:

This reverts commit 90593899. SAM-BA devices identify themselves CDC-ACM devices and should be using the cdc-acm driver. Since commit 5b239f0a (USB: cdc-acm: Add pseudo modem without AT command capabilities) cdc-acm also binds to them. Note that the Atmel SAM-BA tools expect to use a USB-serial driver and thus require a symlink from /dev/ttyACMn to some /dev/ttyUSBm (with m < 30) to be able to select the device. This is simply a UI-issue that should be fixed by Atmel. Tested with the SAM-BA 2.10 tools and an Atmel at91sam9260-ek. Signed-off-by:

The twl4030-usb driver exports the status of VBUS as sysfs attribute. In case an accessory charger adapter (ACA) is connected to the OTG transceiver the attribute is always 'off', even when the charger provides VBUS. Added a variable to keep track of the status of VBUS and report it correctly Signed-off-by:

The ep0 request tag was not recorded thus resulting in phase problems while sending status/response in handle_execption() handler. This was resulting in MSC compliance test failures with USBCV tool.

This patch (as1457) abandons the curious strategy of declaring a controller dead following hibernation merely in order to reset and then revive it. The core no longer allow dead controllers to spring back to life when the system resumes, so there's no reason to declare a working controller temporarily dead. Instead we do an explicit reset.

This patch (as1456) removes all uses of hcd->state from the uhci-hcd driver, as part of the overall strategy to eliminate hcd->state completely. Now when a controller dies we call usb_hc_died() directly, instead of relying on the core interrupt handler to see that hcd->state has changed to HC_STATE_HALT and make the call for us.

Fix 41 occurrences of this type of Section mismatch warning in g_mass_storage, g_serial, g_cdc, g_multi, g_nokia, g_ether, g_ffs: (the 75 number reported earlier contained some duplicates.) WARNING: drivers/usb/gadget/g_mass_storage.o(.text+0x687a): Section mismatch in reference from the function fsg_bind() to the function .devinit.text:usb_ep_autoconfig() The function fsg_bind() references the function __devinit usb_ep_autoconfig(). This is often because fsg_bind lacks a __devinit annotation or the annotation of usb_ep_autoconfig is wrong. Also remove __devinit from usb_ep_autoconfig_reset() to prevent possible section mismatch problems with it. Signed-off-by:

This patch (as1455) removes the extra padding sent by g_file_storage and g_mass_storage when the gadget wants to send less data than requested by the host and isn't allowed to halt the bulk-IN endpoint. Although the Bulk-Only Transport specification requires the padding to be present, it isn't truly needed since the transfer will be terminated by a short packet anyway. Furthermore, many existing devices don't bother to send any padding. Signed-off-by:

Mass-storage and file-storage gadgets align the length to maximum-packet-size when preparing the request to receive CBW. This is unnecessary and prevents the controller driver from knowing that a short-packet is expected. It is incorrect to set short_not_ok when preparing the request to receive CBW. CBW will be a short-packet so short_not_ok must not be set. This makes bh->bulk_out_intended_length unnecessary so it is also removed. Signed-off-by:
