This patch reverts the change made four years ago here:
http://www.vg.kernel.org/pub/linux/kernel/people/gregkh/usb/2.4/usb-hid-2.4.25-pre7.patch
UPS's made by MGE can be used with usbhid just fine, and by removing the
ignore quirk allows them to be used with HAL so they just work when plugged
in, without needing to be manually configured.
With the ignore quirk in place a user would have to configure NUT before the
UPS could be used, as NUT uses it's own internal USB matching framework
to match against the USB devices, do low level control messages on the
device and then parse the HID tables all in userspace.
This is not needed, as allowing the device to be claimed as a usbhid device
allows it to be used like any other USB UPS device. The devices correctly
advertise the power device page which can be queried for the device state.
I assume the quirk was changed so that people using < libusb 0.1.8 could
still use NUT's internal HID code to manage the UPS.
libusb 0.1.8 was released quite some time ago: 2004-02-11.
This patch does not break NUT as in drivers/libusb.c the device is force
unbound from the kernel driver using usb_detach_kernel_driver_np () where
it can be controlled like normal.

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.

The WARN_ON() in implement() and extract() spit out stacktraces and
a lot of other information that might make users think that there is
something seriously wrong with the system. WARN_ON() should not be
deliberately triggerable by userspace application, which these can be.
Usually this WARN_ON() triggers when hid2hci utility is sending the
data that don't correspond to the device's report descriptor.
Convert these messages to more friendly printk().

hidraw is an interface that is going to obsolete hiddev one
day.
Many userland applications are using libusb instead of using
kernel-provided hiddev interface. This is caused by various
reasons - the HID parser in kernel doesn't handle all the
HID hardware on the planet properly, some devices might require
its own specific quirks/drivers, etc.
hiddev interface tries to do its best to parse all the received
reports properly, and presents only parsed usages into userspace.
This is however often not enough, and that's the reason why
many userland applications just don't use hiddev at all, and
rather use libusb to read raw USB events and process them on
their own.
Another drawback of hiddev is that it is USB-specific.
hidraw interface provides userspace readers with really raw HID
reports, no matter what the low-level transport layer is (USB/BT),
and gives the userland applications all the freedom to process
the HID reports in a way they wish to.

diagnosis of which required users to recompile their kernels in order
to be able to provide debugging output needed for coding a quirk for

Some HID devices are looking on the unused bits in the HID reports they
receive. This is violating the specification, but we want to make those
devices work. Well-behaving devices are unaffected, as they don't care
about the unused bits.
If bitsused % 8 is 0 all bits in data[] get used and we don't need to
clear anything. Otherwise (bitsused % 8) bits of the last byte get used.
By shifting 1 for (bitsused % 8) bits and subtracting 1 we create a mask
consisting of (bitsused % 8) ones and remaining zeroes. By ANDing we
clear the upper unused bits.
