Try

modprobe usbcore without the .ko end bit.

[shariefbe]

Generate your module dependencies


sudo depmod -a

[shariefbe]

when i use this command am getting the following error...

sharief@sharief-desktop:~$ sudo depmod -a
[sudo] password for sharief:
FATAL: Could not rename /lib/modules/2.6.26/modules.dep.temp into /lib/modules/2.6.26/modules.dep: No such file or directory
sharief@sharief-desktop:~$

[iponeverything]

attach the file /tmp/find.txt from this command:


find /lib/modules > /tmp/find.txt

[shariefbe]

this is the attched txt/find.txt file..

[iponeverything]

backup your original module to /root if you have one:


sudo mv /lib/modules/`uname -r`/kernel/drivers/usb/core/usbcore.ko /root/


Next copy your custom module into its place:


sudo cp /home/sharief/Desktop/drivers/core/usbcore.ko /lib/modules/`uname -r`/kernel/drivers/usb/core/usbcore.ko

rerun our depmod command:


sudo depmod -a


If this depmod fails run this and upload /tmp/debug.txt.


sudo depmod -v -a > /tmp/debug.txt 2>&1


If the depmod did work load your module with:


sudo modprobe usbcore

[shariefbe]

actually i didnt have "usbcore" module in /lib/modules/`uname -r`/kernel/drivers/usb/core/

so i tried the second command....for that i am getting the following error

root@sharief-desktop:/home/sharief# sudo cp /home/sharief/Desktop/drivers/core/usbcore.ko /lib/modules/`uname -r`/kernel/drivers/usb/core/usbcore.ko
cp: cannot create regular file `/lib/modules/2.6.26/kernel/drivers/usb/core/usbcore.ko': No such file or directory
root@sharief-desktop:/home/sharief#

[shariefbe]

but i am getting this command work...

root@sharief-desktop:/home/sharief# sudo depmod -v -a > /tmp/debug.txt 2>&1
root@sharief-desktop:/home/sharief# sudo depmod -a
root@sharief-desktop:/home/sharief#

[iponeverything]

put it in misc:


sudo cp /home/sharief/Desktop/drivers/core/usbcore.ko /lib/modules/`uname -r`/kernel/drivers/misc/usbcore.ko

and rerun your depmod.

[shariefbe]

yes thanks...its working now...

root@sharief-desktop:/home/sharief# sudo cp /home/sharief/Desktop/drivers/core/usbcore.ko /lib/modules/`uname -r`/kernel/drivers/misc/usbcore.ko
root@sharief-desktop:/home/sharief# sudo depmod -a
root@sharief-desktop:/home/sharief# cd Desktop/
root@sharief-desktop:/home/sharief/Desktop# cd drivers/
root@sharief-desktop:/home/sharief/Desktop/drivers# cd core/
root@sharief-desktop:/home/sharief/Desktop/drivers/core# modprobe usbcore

[iponeverything]

i disabled that module while compiling the kernel.....now i am trying to install manually...this is for college project.

There is only so much a person can do. I did the easy part in getting your module to load using the modprobe command, I think you going to have to figure out why it does not work the way you expect on your own.

BTW -- you don't have to "cd" to any special directory for modprobe to work.

[shariefbe]

yes...i dont know why it does not work.....can you help me to make my USB port work...

[iponeverything]

This is school project right? What is the project? I am afraid we can't do your projects for you.

Does USB work with the stock kernel?

[shariefbe]

yes..its college project...my project is "hacking the USB port"...i have to gather all the details about "USB port"...for that i planned to disable the usb support in the menuconfig....after that i compiled the "usbcore" module manually and planned to install dynamically...yes i done that..but now my usb port is not working....now i dont know what to do....can you help me...just now my usb port should work..by installing the module dynamically....Thanks a lot

If your usb works with original default kernel and does not work with your module, I would say that problem is with your module and not with the usb port.

If the issue is with your module, it may mean that you are not quite done with your project yet --

[shariefbe]

yes i know that...for that only am finding help from you...now i have to find the problem with my module....but i dont know how to find and how to rectify that...please help me....

[shariefbe]

i have to make my USB port to work....help me

[iponeverything]

no. I can't help you.

No one is going to be able to give you some magic command for you to paste into your terminal window to make *your* modified usb module do whatever mysterious thing that it is supposed to do - for you to complete *your* assignment.

[shariefbe]

ya Thanks...i didnt ask like that...just i want to know the necessary "modules" which is needed to make USB port work....Thats all...after that i will do the remaining things....

[iponeverything]

foo@lp:~$ lsmod |grep usb
usbcore 148848 3 uhci_hcd,ehci_hcd


FYI - modprobe loads all the necessary ancillary modules.

So -- The problem is with your usbcore.ko.

[shariefbe]

whether i need to install this "uhci_hcd,ehci_hcd" modules?

[iponeverything]

type
lsmod |grep usb and see.

I am done with this thread. Don't expect another response from me. Don't PM me.

Ask your teacher or a classmate for help or use google.

[shariefbe]

ya ok Thanks.....Thanks a lot

I found wusbcore (*.ko) in my kernel is this the same?
