ignore_device

ignore_device

[Edward Siefker]

I am trying to write a udev rule that will cause linux to completely
ignore 
a USB device.  This is necessary because VirtualBox will not load USB
devices
that have been grabbed by the host system.  

Anyway, I created a file '/etc/udev/rules.d/11-blacklist.rules' with the
line:

ATTR{idVendor}="03eb", OPTIONS+="ignore_device"

This seems to have had no effect whatsoever.  What am I doing wrong?  I
would
just blacklist the module, but this device identifies (incorrectly) as
an HID
device.  I need those of course, so that's a problem. 

Am I barking up the wrong tree here?  Is there some other way to get
linux to
not hand my USB device over to the HID driver so it will be available
for VirtualBox?

BTW, I'm using Udev 149 with kernel 2.6.31-1-amd64 on Debian Sid. 
Thanks
for any help.

Use a program like this:
  http://www.linuxha.com/USB/detach.html

(I can't vouch for that particular program, as it's just the result of a
google search, but the libusb usb_detach_kernel_driver_np approach
should be the right thing to do.)

Thanks for that, that did in fact make the device "available" to
VirtualBox.
But VB is still unable to forward it, I guess I'll see what they think
then.  I appreciate the rapid reply :)

This was removed in 148, see NEWS:

  "The option "ignore_device" does no longer exist. There is no way to
  ignore an event, as libudev events can not be suppressed by rules.
  It only prevented RUN keys from being executed, which results in an
  inconsistent behavior in current setups."

You can find the driver (usbhid) in /sys and then write the device
name to the "unbind" file to detach that particular device and make it
available for virtualbox.
