2009-03-30HID: remove compat stuffJiri Slaby
This removal was scheduled and there is no problem with later distros to adapt for the new bus, thanks to aliases. module-init-tools map files are deprecated nowadays, so that the patch which introduced hid ones into the m-i-t won't be accepted and hence there is no reason for leaving compat stuff in.

2009-03-30HID: bring back possibility to specify vid/pid ignore on module loadJiri Kosina
When hid quirks were converted to specialized driver, the HID_QUIRK_IGNORE has been moved completely, as the hid_ignore_list[] has been moved into the generic code. However userspace already got used to the possibility that modprobing usbhid with 'quirks=vid:pid:0x4' makes the device ignored by usbhid driver. So keep this quirk flag in place for backwards compatibility. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2009-03-25HID: autosuspend support for USB HIDOliver Neukum
This uses the USB busy mechanism for aggessive autosuspend of USB HID devices. It autosuspends all opened devices supporting remote wakeup after a timeout unless - output is being done to the device - a key is being held down (remote wakeup isn't triggered upon key release) - LED(s) are lit - hiddev is opened As in the current driver closed devices will be autosuspended even if they don't support remote wakeup. The patch is quite large because output to devices is done in hard interrupt context meaning a lot a queuing and locking had to be touched. The LED stuff has been solved by means of a simple counter. Additions to the generic HID code could be avoided. In addition it now covers hidraw. It contains an embryonic version of an API to let the generic HID code tell the lower levels which capabilities with respect to power management are needed.

2008-10-27HID: fix oops during suspend of unbound HID devicesJiri Slaby
Usbhid structure is allocated on start invoked only from probe of some driver. When there is no driver, the structure is null and causes null-dereference oopses. Fix it by allocating the structure on probe and disconnect of the device itself. Also make sure we won't race between start and resume or stop and suspend respectively.

2008-10-14HID: fix a lockup regression when using force feedback on a PID deviceAnssi Hannula
Commit 8006479c9b75fb6594a7b746af3d7f1fbb68f18f introduced a spinlock in input_dev->event_lock, which is locked when handling input events. However, the hid-pidff driver sleeps when handling events as it waits for reports being sent to the device before changing the report contents again. This causes a system lockup when trying to use force feedback with a PID device, a regression introduced in 2.6.24 and 2.6.23.15. Fix it by extracting the raw report data from struct hid_report immediately when hid_submit_report() is called, therefore allowing drivers to change the contents of struct hid_report immediately without affecting the already-queued transfer. In hid-pidff, re-add the removed usbhid_wait_io() to pidff_erase_effect() instead, to prevent a full report queue from causing the submission to fail, thus not freeing up device memory. pidff_erase_effect() is not called while dev->event_lock is held.

Make a bus from hid core. This is the first step for converting all the quirks and separate almost-drivers into real drivers attached to this bus. It's implemented to change behaviour in very tiny manner, so that no driver needs to be changed this time. Also add generic drivers for both usb and bt into usbhid or hidp respectively which will bind all non-blacklisted device. Those blacklisted will be either grabbed by special drivers or by nobody if they are broken at the very rude base.

2008-05-20HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN.Diego 'Flameeyes' Petteno
Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for non-laptop Apple keyboards of the Aluminium series. The USB version of these don't need Numlock emulation, like the laptop (and Aluminium Wireless) do, as they have a proper keypad. This patch splits the Numlock emulation for Apple keyboards in a different quirk flag, so that it can be enabled for all the keyboards but the Aluminium USB ones. If the Numlock emulation is enabled for Aluminium USB keyboards, the JKL and UIO keys become the numeric pad, and the rest of the keyboard is disabled, included the key used to disable Numlock. Additionally, these keyboard should not have a Numlock at all, as the Numlock key is instead replaced by the 'Clear' key as usual for Apple USB keyboards.

2008-04-22HID: quirk for MS Wireless Desktop Receiver (model 1028)Jim Duchek
Microsoft's wireless desktop receiver (Model 1028) has a bug in the report descriptor -- namely, in four seperate places it uses USAGE_MIN and _MAX when it quite obviously doesn't intend to. In other words, it reports that it has pretty much _everything_ in 'consumer' and 'generic desktop'. And then the X evdev driver believes I have a mouse with 36 absolute axes and a huge pile of keys and buttons, when I in fact, should have zero. 255/256 in three of the cases, and 0-1024 in another. This patch fixes the report descriptor of this device before it enters the HID parser. Signed-off-by: Jim Duchek <jim.duchek@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2008-04-22HID: fixup fullspeed interval on highspeed Afatech DVB-T IR kbdPekka Sarnila
Many vendors highspeed devices give erroneously fullspeed interval value in endpoint descriptor for interrupt endpoints. This quirk fixes up that by recalculating the right value for highspeed device. At the time of hid configuration this quirk calculates which highspeed interval value gives same interval delay as, or next smaller then, what it would be if the original value would be interpreted as fullspeed value. In subsequent urbs that new value is used instead. Forming the 'hid->name' in usb_hid_config() was moved up to accommodate more descriptive printk reporting the fixup. In this patch the quirk is set for one such device: Afatech DVB-T 2 infrared HID-keyboard. It reports value 16 which means 4,069s in highspeed while obviously 16ms was intended. In this case quirk calculates new value to be 8 which gives when interpreted as highspeed value 16ms as wanted. The behavior of the device was verified to be what expected both before and after the patch. Signed-off-by: Pekka Sarnila <sarnila@adit.fi> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
