It seems that I see a bug in hidinput_hid_event.  The check for NULL can never
work, becaue &hidinput->input is nonzero at all times.

below you will find one patch to hid-core.c, which lets usbhid ignore
our HID devices. It would be nice, if you can apply it.

This driver is a basic keypress input driver for the Keyspan Digital
Remote with part number UIA-11.  Currently there is an older remote with
part number UIA-10 which isn't supported by this driver.  Support for
the older UIA-10 could be added but a binary file is required to be
download to the device, and I don't have that file.  I also don't have a
UIA-10 device so I wouldn't be able to test any of the changes.

Currently hid-core follows the same code path for input reports
regardless of whether they are a result of interrupt transfers or
control transfers. That leads to interrupt events erroneously being
reported to hiddev for regular control transfers.

Prior to 2.6.12 the problem was mitigated by the fact that
reporting to hiddev is supressed if the field value has not changed,
which is often the case. Said filtering was removed in 2.6.12-rc1 which
means any input reports fetched via control transfers result in hiddev
interrupt events. This behavior can quickly lead to a feedback loop
where a userspace app, in response to interrupt events, issues control
transfers which in turn create more interrupt events.

This patch prevents input reports that arrive via control transfers from
being reported to hiddev as interrupt events.
