The UHCI controller in my laptop takes longer to turn off the Resume-Detect bit than the 4 us allowed by uhci-hcd. Presumably other computers will have the same problem. This patch (as752) increases the maximum delay to 10 us, which should be plenty, and uses polling to avoid penalizing systems which can turn the bit off more quickly. Signed-off-by:

If some problem occurs during ehci startup, for instance, request_irq fails, echi hcd driver tries it best to cleanup, but fails to unregister reboot notifier, which in turn leads to crash on reboot/poweroff. The following patch resolves this problem by not using reboot notifiers anymore, but instead making ehci/ohci driver get its own shutdown method. For PCI, it is done through pci glue, for everything else through platform driver glue. One downside: sa1111 does not use platform driver stuff, and does not have its own shutdown hook, so no 'shutdown' is called for it now. I'm not sure if it is really necessary on that platform, though. Signed-off-by:

I spotted this during my tests with -rt on arm. The -rt patch contains some better tools to diagnose problems with locks and some other things... Original code tries to take semaphore in BUG_ON and then free the memory with this semaphore. Signed-off-by:

These functions makes USB driver's code simpler when dealing with endpoints by avoiding them from accessing the endpoint's descriptor structure directly when they only need to know the endpoint's transfer type and/or direction. Please, read each functions' documentation in order to know how to use them. Signed-off-by:

This driver is glue between the USB gadget interface and the ALSA MIDI interface. It allows us to appear as a MIDI Streaming device to a host system on the other end of a USB cable. This includes linux/usb/audio.h and linux/usb/midi.h containing definitions from the relevant USB specifications for USB audio and USB MIDI devices. The following changes have been made since the first RFC posting: * Bug fixes to endpoint handling. * Workaround for USB_REQ_SET_CONFIGURATION handling, not understood yet. * Added SND and SND_RAWMIDI dependencies in Kconfig. * Moved usb_audio.h and usb_midi.h to usb/*.h * Added module parameters for ALSA card index and id. * Added module parameters for USB descriptor IDs and strings. * Removed some unneeded stuff inherited from zero.c, more to go. * Provide DECLARE_* macros for the variable-length structs. * Use kmalloc instead of usb_ep_alloc_buffer. * Limit source to 80 columns. * Return actual error code instead of -ENOMEM in a few places.

This patch fixes ep_config to return correct value. Without patch ep_config returns submitted lenght minus 4 on succes. With this patch applied, whole submitted lenght is returned. ep_config parses submitted data and if buffer starts with (int) 1 it is parsed, otherwise error is reported. Problem is that ep_config returns size of buffer minus 4 on success. I think that size of buffer should be returned instead, because there were no problems and all data were processed. Signed-off-by:

The ohci-omap code has diverged from the working version in the linux-omap tree; this syncs up the versions: - Another clock is needed in various cases - The omap-1510 iommu code needs to be #ifdeffed out on newer parts - Saner use of the HCD framework - Various other changes, e.g. a Nokia 770 quirk And some minor dead-whitespace removal.

This patch uses completion timeout instead of a timer to implement a timeout when submitting an URB in usb_start_wait_urb(). It also fixes a small issue. With the previous code, if no timeout happened and the URB's status was set to ECONNRESET value, the code assumed wrongly that a timeout had occured. Signed-off-by:

Commit b512504er085c4b1832f623d3 made ipaq_open() a bit messy by moving the read urb submission far from its usb_fill_bulk_urb() call and the comment explaining what it does. This patch put they together again. Although only compiled tested, should not break the fix introduced by b512504er085c4b1832f623d3, of course. Signed-off-by:

Fix printk format warning(s): drivers/usb/net/usbnet.c:654: warning: int format, different type arg (arg 3) The fact that rx_urb_size happens to be a size_t has propagated all the way back to this printk. It's fragile to be using %z in this case - let's just typecast the args instead. Signed-off-by:

Since usb_generic can be unbound from a USB device, we need to be able to handle the possibility that a suspend or resume request arrives for a device with no driver. This patch (as735) arranges things so that resume requests will fail and suspend requests will use the standard USB port-suspend code. Attempts to suspend or resume an unbound interface are handled similarly (although the error caused by trying to resume an unbound interface is dropped by the calling routine). Signed-off-by:

This patch (as734) rationalizes the various tests of device state and power states. There are duplications and mistaken tests in several places. Perhaps the most interesting challenge is where the hub driver tests to see that all the child devices are suspended before allowing itself to be suspended. When CONFIG_USB_SUSPEND is set the test is straightforward, since we expect that the children _will_ be suspended. But when CONFIG_USB_SUSPEND isn't set, it's not so clear what should be done. The code compromises by checking the child's power.power_state.event field. Signed-off-by:
