Hi,
I need some understanding regarding usbHID driver
I had one device called footpedal usb device, when I connected that
device to the HOST machine RHEL , default usbHID driver is detecting
my footpedal i,e usbhid driver.
Actually
I dont want usbHID driver to detect foot pedal device, it would have been nice if there was just a nice simple way of stopping the kernel usbHID driver from getting in the way, I want this pedal detected by
my own modified mouse driver.
please
suggest me in this regard or suggest me whether this is possible or not
without compiling the whole source kernel and compiling only my module and insert
that module.
I am through udev
related stuff , am i going in the right path, going through ?.
I have written the udev rule like this below
BUS!="usb", ACTION!="add", GOTO="footpedal_add_end"
BUS=="usb", SYSFS{idVendor}=="ffff", SYSFS{idProduct}=="0000", \
ACTION=="add", RUN+="/sbin/insmod footpedal"
LABEL="footpedal_add_end"
KERNEL=="event*", SYSFS{idVendor}=="ffff", SYSFS{idProduct}=="0000", \
ACTION=="add", NAME="input/%k", SYMLINK+="test_pedal", \ OPTIONS="remove_symlinks"
BUS!="usb", ACTION!="remove", GOTO="foorpedal_remove_end"
BUS=="usb", SYSFS{idVendor}=="ffff", SYSFS{idProduct}=="0000", \
ACTION=="remove", RUN+="/sbin/rmod test_pedal"
LABEL="footpedal_remove_end"
But
this did not work for me, because HID driver default static built one,
so when I restart the HOST, HID driver is getting registered with
footpedal device first and then UDEV rules coming int picture whis is
of no use for me.
please suggest me in this regard how can I get my device registered with my foot pedal driver module.
Waiting for valuable reply
Sincerely
Kumar Manchala
