Less ancient windows drivers, even those from a few years ago, perform extra initialization steps which this patch adds to the linux driver. David Woodhouse observed that this initialization along with the firmware bin/sachu3/zzzlp2.eni from the driver at http://www.speedtouch.co.uk/downloads/330/301/UK3012%20Extended.zip improves line sync speeds by about 20%. He provided the original patch, which I've modified to use symbolic names (BMaxDSL, ModemMode, ModemOption) rather than magic numbers. These names may not seem like much of an improvement (after all, what is "ModemOption" exactly?), but they do have one big advantage: they are the names used in the windows registry. I've made them available as module parameters. Thanks are due to Aurelio Arroyo, who noticed the relationship between these magic numbers and the entries in Phonebook.ini.

It is based on the usbnet and asix drivers as well as the original device driver provided by MosChip, which in turn was based on the usbnet driver. It has been tested successfully on an OHCI, but interestingly there seems to be a problem with the mcs7830 when connected to the ICH6/EHCI in my thinkpad: it keeps receiving lots of broken packets in the RX interrupt. The problem goes away when I'm using an active USB hub, so I assume it's not related to the device driver, but rather to the hardware.

These are now implemented using mii functions when a low-level driver supports mdio_read/mdio_write and does not override the usbnet ethtool commands with its own. Currently, this applies to the asix and the mcs7830 drivers. I have tested it on mcs7830.

A related problem seems to be present in the asix driver in the respective functions. This introduces a mutex in the common usbnet driver and uses it from the two hardware specific drivers.

The problem is the index math in the original code didn't clear all the relevant bits. (offset >> 5) only compensated for 32-bit index. We need (offset >> 6) if we want to use 64-bit loads. But it was also wrong in that it tried to use quasi-aligned loads. Ie "report" was only incremented in multiples of 4 bytes and then the offset was masked off for values greater than 4 bytes. The right way is to pretend "report" points at a byte array. And offset is then only minor adjustment for < 8 bits of offset. "n" (field width) can then be as big as 24 (assuming 32-bit loads) since "offset" will never be bigger than 7. If someone needs either function to handle more than 24-bits, please document why - point at a specification or specific USB hid device - in comments in the code. extract/implement() are also an eyesore to read. Please banish whoever wrote it to read CodingStyle 3 times in a row to a classroom full of 1st graders armed with rubberbands. Or just flame them. Whatever. Globbing all the code together on two lines does NOT make it faster and is Just Wrong. I've tested this patch on j6000 (dual 750Mhz PA-RISC, 32-bit 2.6.12-rc5). Kyle McMartin tested on c3000 (up 400Mhz PA-RISC, same kernel). "p2-mate" (Peter De Schrijver?) tested on sb1250 (dual core Mips, broadcom "swarm" eval board).

Dance pads require the d-pad to be mapped to four buttons instead of two axes, so that combinations of up/down and left/right can be hit simultaneously. Known dance pads are detected, and there is a module parameter added to default unknown xpad devices to map the d-pad to buttons if this is desired. (dpad_to_buttons). Minor modifications were made to port the changes in the original patch to a newer kernel version. This patch was originally from Dominic Cerquetti originally written for kernel 2.6.11.4, with minor modifications (API changes for USB, spelling fixes to the documentation added in the original patch) made to apply to the current kernel. I have modified Dominic's original patch per some suggestions from Dmitry Torokhov. (There was nothing in the patch format description about multiple From: lines, so I haven't added myself.)

This patch also updates the current sierra.c driver so that it supports both 3-port Sierra devices and 1-port legacy devices and removes Sierra's references in other related files (Kconfig and airprime.c).

However, there does seem to be a Kconfig reverse dependency bug in that MII gets wrongly enabled in some cases (like USBNET=y and USBNET_MII=n); I think I've noticed that same problem in other situations too. So the result can mean kernels being bloated by stuff that's needlessly enabled ... better than wrongly being disabled, but contributing to bloat.

The first one contains fields from HID_UP_KEYBOARD and HID_UP_LED, and the other one contains fields from HID_UP_CONSUMER and HID_UP_LOGIVENDOR. This device is used with multiple wireless Logitech products, including UltraX Media Remote. All fields on both interfaces are either keys or leds. All fields in the first interface are marked as Absolute, while the fields in the second interface are marked as Relative. Marking the keys as relative causes hidinput_hid_event() to send release events right after key press events. The device has EV_REP set, so the userspace expects the device to send repeat events if a key is held down. However, as hidinput_hid_event() sends release events immediately, repeat events are not sent at all. In fact, the userspace has no way of knowing if a key is being held down. Fix this by adding a quirk for 046d:c101 which changes relative keys to absolute ones.

Previously, it recognized a new finger when a low sensor reading is followed by a high sensor reading. The new method checks for 'humps' in the sensor readings, so there doesn't necessarily have to be a low sensor between two high sensors for two fingers to be triggered. This allows detecting presence of two fingers on the touchpad even when they touch each other. - Change absolute coordinate calculation to us to get rid of "jumps". Instead of using full value from a sensor once it passes the threshold subtract theshold value from the reading. - Allow adjusting threshold value via module parameter. The patch doesn't seem to affect the Powerbooks but does greatly improve the touchpad behaviour on the MacBooks.

Upcoming hardware might raise that limit. Makes almost no difference to go to 31, as the bit arrays are byte-aligned (plus an extra bit in general), so 22 bits fit in 4 bytes as 31 do. As well, the only other array that depends on USB_MAXCHILDREN is 'struct usb_hub->indicator'. By declaring it 'u8' instead of 'enum hub_led_mode', we reduce the size of each entry from 4 bytes (in i386) to 1, which will add as we when are doubling USB_MAXCHILDREN (with 16 the size of that array is 64 bytes, with 31 would be 128; by using u8 that goes down to 31 bytes).

Drivers can override this policy by specifying a Vendor ID as part of the match; then vendor-specific matches are allowed. Linus Walleij has reported a problem this patch fixes. When a particular mass-storage device is switched from mass-storage mode to Media Transfer Protocol, the interface class remains set to mass-storage and usb-storage binds to it erroneously, even though the device class changes to Vendor-Specific. This may cause a problem for some drivers until their match records can be updated to include Vendor IDs. But if it does, then those records were broken to begin with.

This looks like a hardware error, at the level of noise to those ports' overcurrent input signals (or non-debounced VBUS comparators). This surfaces to users as truly massive amounts of syslog spam from khubd (which is appropriate for real hardware problems, except for the volume from multiple ports). Using this new "ignore_oc" flag helps such systems work more sanely, by preventing such indications from getting to khubd (and spam syslog). The downside is of course that true overcurrent errors will be masked; they'll appear as spontaneous disconnects, without the diagnostics that will let users troubleshoot issues like short circuited cables. Note that the bulk of these reports seem to be with VIA southbridges, but I think some were with Intel ones.

Ports that were already suspended should remain that way. The interrupt mask is used to detect loss of power in the bus_resume() routine (if the mask is 0 then power was lost). However bus_suspend() always sets the mask to 0. Instead the mask should retain its normal value, with port-change-detect interrupts disabled if remote wakeup is turned off. The interrupt mask should be reset to its correct value at the end of bus_resume() regardless of whether power was lost. bus_resume() reinitializes the operational registers if power was lost. However those registers are not in the aux power well, hence they can lose their values whenever the controller is put into D3. They should always be reinitialized. When a port-change interrupt occurs and the root hub is suspended, the interrupt handler should request a root-hub resume instead of starting up the controller all by itself. There's no need for the interrupt handler to request a root-hub resume every time a suspended port sends a remote-wakeup request. The pci_resume() method doesn't need to check for connected ports when deciding whether or not to reset the controller. It can make that decision based on whether Vaux power was maintained. Even when the controller does not need to be reset, pci_resume() must undo the effect of pci_suspend() by re-enabling the interrupt mask. If power was lost, pci_resume() must not call ehci_run(). At this point the root hub is still supposed to be suspended, not running. It's enough to rewrite the command register and set the configured_flag.

Consequently there is no advantage to doing an autostop other than the power savings, so we shouldn't compile the necessary code unless CONFIG_PM is enabled. This patch (as820) makes the root-hub suspend and resume routines conditional on CONFIG_PM. It also prevents autostop from activating if the device_may_wakeup flag isn't set; some people use this flag to alert the driver about Resume-Detect bugs in the hardware.

Now instead of using a specialized code path, it relies on the standard USB resume routines. The hub_port_resume() function does an initial get_port_status() to see whether the port has already resumed itself (as it does when a remote-wakeup request is sent). This will slow down handling of other resume events slightly, but not enough to matter. The patch also changes the hub_port_status() routine, making it return an error if a short reply is received.

This will permit us to avoid a good deal of unnecessary work all the time; we will no longer have to create a bunch of workqueue entries to carry out autosuspend requests, only to have them fail because one of the hub's children isn't suspended. The basic idea is simple. There already is a usage counter in the usb_device structure for preventing autosuspends. The patch just increments that counter for every unsuspended child. There's only one tricky part: When a device disconnects we need to remember whether it was suspended at the time (leave the counter alone) or not (decrement the counter).

This patch (as819) removes the now-redundant argument. It also consolidates some common code between those two routines, putting it into a new subroutine called usb_autopm_do_device(). And it includes a sizable kerneldoc update for the affected functions.

USB HID is disabled, so that the code split and changes could be introduced in a way that is reviewable (i.e. separate patches), but not to break git bisect by uncompilable kernel throughout different stages of the code splitup and changes. The last patch of this series enables HID again.
