The "c-enter" USB to Toshiba 1.8" IDE enclosure needs special treatment to work flawlessly. This patch is absolutely trivial, as the integrated USB-IDE bridge is already identified to be an "unusual" device, only the bcdDevice is different (lower) to the bcdDeviceMin already included in the kernel. It is a Prolific 2507 bridge.

This patch (as1225) fixes a bug in ehci-hcd. The condition for whether unlinked QHs can become IDLE should not be that the controller is halted, but rather that the controller isn't running. In other words when the root hub is suspended, the hardware doesn't own any QHs. This fixes a problem that can show up during hibernation: If a QH is only partially unlinked when the root hub is frozen, then when the root hub is thawed the QH won't be in the IDLE state. As a result it can't be used properly for new URB submissions.

ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing isochronous URB's kref.counts incrementing once per usb_submit_urb() call. The culprit is *usb being set to NULL when usb_put_urb() is called after URB is given back. Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb() nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd. Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a stream finishes.

The usbfs driver manages a list of completed asynchronous URBs. But it is too eager to free the entries on this list: destroy_async() gets called whenever an interface is unbound or a device is removed, and it deallocates the outstanding struct async entries for all URBs on that interface or device. This is wrong; the user program should be able to reap an URB any time after it has completed, regardless of whether or not the interface is still bound or the device is still present. This patch (as1222) moves the code for deallocating the completed list entries from destroy_async() to usbdev_release(). The outstanding entries won't be freed until the user program has closed the device file, thereby eliminating any possibility that the remaining URBs might still be reaped. This fixes a bug in which a program can hang in the USBDEVFS_REAPURB ioctl when the device is unplugged.

For some strange reason the host side musb_giveback() decides that it's always got an IN transfer when the hardware endpoint is using a shared FIFO. This causes musb_save_toggle() to read the toggle state from the RXCSR register instead of TXCSR, and may also cause unneeded reloading of RX endpoint registers.

The musb_h_disable() routine can oops in some cases: - It's not safe to read hep->hcpriv outside musb->lock, since it gets changed on completion IRQ paths. - The list iterators aren't safe to use in that way; just remove the first element while !list_empty(), so deletions on other code paths can't make trouble.

The urb_dequeue() method forgets to unlink 'struct musb_qh' from the control or bulk schedules when the URB being cancelled is the only one queued to its endpoint. That will cause musb_advance_schedule() to block once it reaches 'struct musb_qh' with now empty URB list, so URBs queued for other endpoints after the one being dequeued will not be served. Fix by unlinking the QH from the list except when it's already being handled (typically by musb_giveback). Since a QH with an empty URB list is now supposed to be freed, do that. And remove a now-useless check from musb_advance_schedule().

Now that the musb build fixes for DaVinci got merged (RC3?), kick in the other bits needed to get it finally *working* in mainline: - Use clk_enable()/clk_disable() ... the "always enable USB clocks" code this originally relied on has since been removed. - Initialize the USB device only after the relevant I2C GPIOs are available, so the host side can properly enable VBUS. - Tweak init sequencing to cope with mainline's relatively late init of the I2C system bus for power switches, transceivers, and so on. Sanity tested on DM6664 EVM for host and peripheral modes; that system won't boot with CONFIG_PM enabled, so OTG can't yet be tested. Also verified on OMAP3.

This patch (as1218) fixes a problem with a radio-control joystick used in the "walkera 4#3" helicopter. This device responds to the initial Get-String-Descriptor request for string 0 (which is really the list of supported languages) by sending its config descriptor! The usb_get_string() routine needs to check whether it got the right type of descriptor. Oddly enough, this sort of check is already present in usb_get_descriptor(). The patch changes the error code from -EPROTO to -ENODATA, because -EPROTO shows up in so many other contexts to indicate a hardware failure rather than a firmware error.

Currently ITDs are immediately recycled whenever their URB completes. However, EHCI hardware can sometimes remember some ITD state. This means that when the ITD is reused before end-of-frame it may sometimes cause the hardware to reference bogus state. This patch defers reusing such ITDs by moving them into a new ehci member cached_itd_list. ITDs resting in cached_itd_list are moved back into their stream's free_list once scan_periodic() detects that the active frame has elapsed. This makes the snd_usb_us122l driver (in kernel since .28) work right when it's hooked up through EHCI.
