* HID: fix oops during suspend of unbound HID devicesJiri Slaby2008-10-27
| | | | | | | | | | | | | | | | | 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.

* HID: add hid_type to general hid structJiri Slaby2008-10-22
| | | | | | | | | | | | Add type to the hid structure to distinguish to which device type (now only mouse) we are talking to. Needed for per device type ignore list support. Note: this patch leaves the type as unknown for bluetooth devices, there is not support for this in the hidp code.

* HID: fix a lockup regression when using force feedback on a PID deviceAnssi Hannula2008-10-14
| | | | | | | | | | | | | | | | | | | | | | | 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.

* HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN.Diego 'Flameeyes' Petteno2008-05-20
| | | | | | | | | | | | | | | | | | | | | | 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.

* HID: quirk for MS Wireless Desktop Receiver (model 1028)Jim Duchek2008-04-22
| | | | | | | | | | | | | | | | | 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>
* HID: fixup fullspeed interval on highspeed Afatech DVB-T IR kbdPekka Sarnila2008-04-22
| | | | | | | | | | | | | | | | | | | | | | | 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>

* HID: Support Samsung IR remoteRobert Schedel2008-01-28
| | | | | | | | | | | | | | | | | Samsung USB remotes (0419:0001) are rejected by kernel 2.6.23, because the report descriptor from the remote contains a 48 bit HID report field. HID 1.11 states: Fields may span at most 4 bytes. This patch, based on 2.6.23, fixes this by modifying the internal report descriptor in hid-quirks.c. Additional user space support (e.g. LIRC) is required to fetch the information from the hiddev interface. The burden to reconstruct the data is moved into userspace (lirc through hiddev). There is no need to set HID_QUIRK_HIDDEV quirk, as the device has also output applications, which trigger the creation of hiddev device automatically.

* HID: hid-input quirk for BTC 8193Jiri Kosina2008-01-28
| | | | | | | | | | | | | | | | BTC 8193 keyboard handles its scrollwheel in very non-standard way. It produces two non-standard usages for scrolling up and down, in both cases with postive value equaling to 1. We handle this by temporary mapping, which we then catch in quirk event handler, and remap to negative HWHEEL even in order to introduce correct behavior. Also the button requires special mapping, as it triggers standard-violating usage code.
