2009-02-27USB: usb_get_string should check the descriptor typeAlan Stern
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.

2009-02-27USB: EHCI: slow down ITD reuseKarsten Wiese
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.

2009-02-17USB/PCI: Fix resume breakage of controllers behind cardbus bridgesRafael J. Wysocki
If a USB PCI controller is behind a cardbus bridge, we are trying to restore its configuration registers too early, before the cardbus bridge is operational. To fix this, call pci_restore_state() from usb_hcd_pci_resume() and remove usb_hcd_pci_resume_early() which is no longer necessary (the configuration spaces of USB controllers that are not behind cardbus bridges will be restored by the PCI PM core with interrupts disabled anyway). This patch fixes the regression from 2.6.28 tracked as http://bugzilla.kernel.org/show_bug.cgi?id=12659 [ Side note: the proper long-term fix is probably to just force the unplug event at suspend time instead of doing a plug/unplug at resume time, but this patch is fine regardless - Linus ] Signed-off-by: Rafael J.

While disabling an endpoint the driver nuking any pending requests, thus completing them with -ESHUTDOWN status. But the driver doesn't clear the tx_req, which means that a next TX request (after ep_enable), might get stalled, since the driver won't queue the new reqests.

Before freeing an endpoint's muram memory, we should stop all activity of the endpoint, otherwise the QE UDC controller might do nasty things with the muram memory that isn't belong to that endpoint anymore. The qe_ep_reset() effectively flushes the hardware fifos, finishes all late transaction and thus prevents the corruption.

2009-02-09USB: fsl_qe_udc: Fix disconnects reporting during bus resetAnton Vorontsov
Freescale QE UDC controllers can't report the "port change" states, so the only way to handle disconnects is to process bus reset interrupts. The bus reset can take some time, that is, few irqs. Gadgets may print the disconnection events, and this causes few repetitive messages in the kernel log. This patch fixes the issue by using the usb_state machine, if the usb controller has been already reset, just quit the reset irq early.

This patch adds support for the FHCI USB controller, as found in the Freescale MPC836x and MPC832x processors. It can support Full or Low speed modes. Quite a lot the hardware is doing by itself (SOF generation, CRC generation and checking), though scheduling and retransmission is on software's shoulders.
