This patch (as1149) fixes an obscure problem in OHCI polling. In the current code, if the RHSC interrupt status flag turns on at a time when RHSC interrupts are disabled, it will remain on forever: The interrupt handler is the only place where RHSC status gets turned back off; The interrupt handler won't turn RHSC status off because it doesn't turn off status flags if the corresponding interrupt isn't enabled; RHSC interrupts will never get enabled because ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC status is on! As a result we will continue polling indefinitely instead of reverting to interrupt-driven operation, and the root hub will not autosuspend. This particular sequence of events is not at all unusual; in fact plugging a USB device into an OHCI controller will usually cause it to occur. Of course, this is a bug. The proper thing to do is to turn off RHSC status just before reading the actual port status values. That way either a port status change will be detected (if it occurs before the status read) or it will turn RHSC back on. Possibly both, but that won't hurt anything. We can still check for systems in which RHSC is totally broken, by re-reading RHSC after clearing it and before reading the port statuses. (This re-read has to be done anyway, to post the earlier write.) If RHSC is on but no port-change statuses are set, then we know that RHSC is broken and we can avoid re-enabling it.

This patch adds initial_descriptor_timeout module parameter for usbcore.ko to allow modify initial 64-byte USB_REQ_GET_DESCRIPTOR timeout for non-standard devices. For example, the SATA8000 device from DATAST0R Technology Corp requires about 10 seconds to send reply (probably it waits until inserted disk is ready for operation). Also, this patch adds missing usbcore parameters to Documentation/kernel-parameters.txt.

Create a new sysfs file per interface named supports_autosuspend. This file returns true if an interface driver's .supports_autosuspend flag is set. It also returns true if the interface is unclaimed (since the USB core will autosuspend a device if an interface is not claimed). This new sysfs file will be useful for user space scripts to test whether a USB device correctly auto-suspends.

This patch (as1147) fixes the remote-wakeup support for EHCI controllers using the ARC/TDI "embedded-TT" core. These controllers turn off the RESUME bit by themselves when a port resume is complete; hence we need to keep separate track of which ports are suspended or in the process of resuming. The patch also makes a couple of small improvements in ehci_irq(), replacing reads of the command register with the value already stored in a local variable.

The kernel doc for usb_bulk_msg() says the timeout for a bulk message should be specified in milliseconds. The ftdi-elan driver converts milliseconds to jiffies before passing the timeout to usb_bulk_msg(). This is mostly harmless, since it will just lead to very long timeouts, but was obviously not the intent of the original author.

In case of error, the function isp1760_register returns an ERR pointer, but never returns a NULL pointer. So after a call to this function, a NULL test should be replaced by an IS_ERR test. Moreover, we have noticed that: (1) the result of isp1760_register is assigned through the function pci_set_drvdata without an error test, (2) if the call to isp1760_register fails, the current function (isp1761_pci_probe) returns 0, and if it succeeds, it returns -ENOMEM, which seems odd. Thus, we suggest to move the test before the call to pci_set_drvdata to correct (1), and to turn it into a non IS_ERR test to correct (2). The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @bad_null_test@ expression x,E; statement S1, S2; @@ x = isp1760_register(...) ... when != x = E * if (x == NULL) S1 else S2 // </smpl> Signed-off-by: NJulien Brunel <brunel@diku.dk> Signed-off-by: NJulia Lawall <julia@diku.dk> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

ehci_watchdog will wake up CPU very frequently so that CPU stays at C3 very short, average residence time is about 50 ms on Aspire One, but we expect it should be about 1 second or more, so this kind of periodic timer is very bad for power saving. We can't remove this timer because of some bad USB controller chipset, but at least we should reduce its side effect to as possible as low. This patch can make CPU stay at C3 longer, average residence time is about twice as long as original.

This patch (as1140) adds a little intelligence to the interrupt-URB scheduler in uhci-hcd. Right now the scheduler is stupid; every URB having the same period is assigned to the same slot. Thus a large group of period-N URBs can fill their slot and cause -ENOSPC errors even when all the lower-period slots are empty. With the patch, if an URB doesn't fit in its assigned slot then the scheduler will try using lower-period slots. This will provide greater flexibility. As an example, the driver will be able to handle more than just three or four mice, which the current driver cannot.

Bugfix for the new CDC Ethernet code: as part of activating the network interface's USB link, make sure its link management code knows whether the interface is open or not. Without this fix, the link won't work right when it's brought up before the link is active ... because the initial notification it sends will have the wrong link state (down, not up). Makes it hard to bridge these links (on the host side), among other things.
