Subject: Forcing the HID-USB driver to ignore an external 'keyboard'.
To: email@hidden
I'm trying to write a libusb (http://libusb.sourceforge.net/) based
'driver' for a Nostromo n52 SpeedPad
(http://catalog.belkin.com/IWCatProductPage.process?Merchant_Id=&Section_Id=2071&pcount=&Product_Id=157024
; there's an existing Mac OS X driver from the vendor, which is not
quite good enough for my purposes). The n52 is a nice HID keyboard as
far as USB is concerned.
I've got the device detected and useful with the builtin HID driver;
so I know it works. As a joystick, it's doing great in games.
Problem is that when my program tries to access the device from
userland, it detects the device, tries to connect to the device and
gets an error from the device when trying to initialize it. I'm
assuming that this because the HID driver has already taken over the
device.
The userland program also works great under linux 2.6, once I tell the
driver to ignore the device. It displays the exact same symptoms if I
don't.
Question is:
Is it really likely to be the HID driver, and if so, how can I tell
the HID driver to ignore a specific device so I can access it raw from
userspace using libusb?
(Also, lemme know if I'm talking to the wrong mailing list, please :)
Have fun,
