No USB at all

BobNutfield · 04-18-2006, 05:44 PM

Hi Everyone,

Well just when I thought I was home free with this new kernel, tonight I find I have NO USB at all. All was well with the 2.4 kernel and I KNOW I enabled USB support. lsusb returns this:

Quote:

Bus 001 Device 001: ID 0000:0000

lspci shows that the controller was recognized:

Quote:

00:02.0 USB Controller: nVidia Corporation CK8S USB Controller (rev a1)
00:02.1 USB Controller: nVidia Corporation CK8S USB Controller (rev a1)
00:02.2 USB Controller: nVidia Corporation nForce3 EHCI USB 2.0 Controlle

But, USB printer no longer is recognized (no such device error) and usb camera not recognized.

Anyone have any ideas?

Any help appreciated.

Bob

go through the config again

there is a lot more besides the basic usb support
ie: usb 2.0, usb printer, usb hid, usb webcams,
usb mass storage, usb mouse, usb camera, usb modem, etc...

Hi Bob,

This vaguely rings a bell, in that when I went to 2.6 I was missing a module so I had USB2 but not USB1.1 I needed to have both ehci_hcd and uhci_hcd modprobe'd for the USB to work.

In any case, do you think you could post the output of lsusb? That might reveal something. Also 'dmesg | grep usb' may throw up a relevant message or two.

Cheers,

TIM

Hi thanks for responding. Tim, I listed the total output of lsusb in my opening post, only one line:

Bus 001 Device 001: ID 0000:0000

dmesg | grep usb:

Quote:

root@bobsbox:/home/bob# dmesg | grep usb
usbcore: registered new driver usbfs
usbcore: registered new driver hub
usbmon: debugfs is not available
usb usb1: configuration #1 chosen from 1 choice
usbcore: registered new driver usblp
drivers/usb/class/usblp.c: v0.13: USB Printer Device Class driver
usbcore: registered new driver usb-storage
usbcore: registered new driver usbhid
drivers/usb/input/hid-core.c: v2.6:USB HID core driver

Looks like its all there, however, I looked at /etc/rc.d/rc.modules and it looks like everything still is commented:

Quote:

ard):
#/sbin/modprobe usb-uhci
# Universal Host Controller Interface (alternate JE):
#/sbin/modprobe uhci
# Open Host Controller Interface (Compaq/Microsoft/National standard):
#/sbin/modprobe usb-ohci

Am I seeing this correctly:

Thanks for your help.

Ach - sorry. I meant to say the output of 'lsmod', not 'lsusb'.

Do not forget usb_ohci.

Compiling your own kernel does not make any changes to rc.modules. If you want to manually load a module, you need to uncomment the appropriate modprobe line yourself.

Thanks to Everyone...got it sorted. After trying several things with modprobe, I finally took kodon's advise and recompiled. Hassle, umpteenth time, but appraently I had forgotten something because now it works. Not sure why because when I compile the kernel I take notes on what I have selected and all of the things I selected on this recompile were already in my notes. But, what the heck, it works now.

Thanks to everyone.
