2009-04-17HID: Add support for the G25 force feedback wheel in native modeChristophe Borivant
Add Product Id 0xc299 for the Logitech G25 force feedback wheel The Logitech G25 force feedback wheel, is first recognize by the kernel with the product id "0xc294". In this mode, we can't use all the axes and buttons of the wheel. Using a userland utility, it is possible to make the wheel switch to native mode -- http://svn.vdrift.net/viewvc.cgi/trunk/tools/G25manage/?root=VDrift In native mode, the wheel change its id number to "0xc299". The packet that needs to be sent to the wheel to swtich to native mode and change its PID is { 0xf8, 0x10, 0x00, 0x00, 0x00, 0x00, 0x00 } Signed-off-by: Christophe Borivant <christophe.borivant@wanadoo.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

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: fix race between usb_register_dev() and hiddev_open()Oliver Neukum
upon further thought this code is still racy. retval = usb_register_dev(usbhid->intf, &hiddev_class); here you open a window during which open can happen if (retval) { err_hid("Not able to get a minor for this device."); hid->hiddev = NULL; kfree(hiddev); return -1; } else { hid->minor = usbhid->intf->minor; hiddev_table[usbhid->intf->minor - HIDDEV_MINOR_BASE] = hiddev; and will fail because hiddev_table hasn't been updated The obvious fix of using a mutex to guard hiddev_table doesn't work because usb_open() and usb_register_dev() take minor_rwsem and we'd have an AB-BA deadlock. We need a lock usb_open() also takes in the right order and that leaves only one option, BKL. I don't like it but I see no alternative. Once the usb_open() implements something better than lock_kernel(), we could also do so. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
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.

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.

2009-03-16Rationalize fasync return valuesJonathan Corbet
Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

2009-03-10HID: fix waitqueue usage in hiddevJohannes Weiner
DECLARE_WAITQUEUE doesn't initialize the wait descriptor's task_list to 'empty' but to zero. prepare_to_wait() will not enqueue the descriptor to the waitqueue and finish_wait() will do list_del_init() on a list head that contains NULL pointers, which oopses. This was introduced by 079034073 "HID: hiddev cleanup -- handle all error conditions properly". The prior code used an unconditional add_to_waitqueue() which didn't care about the wait descriptor's list head and enqueued the thing unconditionally. The new code uses prepare_to_wait() which DOES check the prior list state, so use DEFINE_WAIT instead.

For quite some time users with various UPSes from Powercom were forced to play magic with bind/unbind in /sys in order to be able to see the UPSes. The beasts does not work as HID devices, even if claims to do so. cypress_m8 driver works with the devices instead, creating a normal serial port with which normal UPS controlling software works.

2009-01-07USB: change interface to usb_lock_device_for_reset()Alan Stern
This patch (as1161) changes the interface to usb_lock_device_for_reset(). The existing interface is apparently not very clear, judging from the fact that several of its callers don't use it correctly. The new interface always returns 0 for success and it always requires the caller to unlock the device afterward. The new routine will not return immediately if it is called while the driver's probe method is running. Instead it will wait until the probe is over and the device has been unlocked. This shouldn't cause any problems; I don't know of any cases where drivers call usb_lock_device_for_reset() during probe.
