Default strange usb trouble...

Hi there,

Some may remember me having trouble with my Compaq Presario SR1675CL - a
noapic option got me to the point that I have a system now that works.
One thing still puzzles me though: I cannot see any usb devices. Here are
my diagnostics:

family:/home/kai# lspci
00:00.0 Host bridge: ATI Technologies Inc RS480 Host Bridge (rev 10)
00:01.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge
00:12.0 IDE interface: ATI Technologies Inc IXP SB400 Serial ATA
Controller
00:13.0 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller
00:13.1 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller
00:13.2 USB Controller: ATI Technologies Inc IXP SB400 USB2 Host
Controller
00:14.0 SMBus: ATI Technologies Inc IXP SB400 SMBus Controller (rev 11)
00:14.1 IDE interface: ATI Technologies Inc IXP SB400 IDE Controller
00:14.3 ISA bridge: ATI Technologies Inc IXP SB400 PCI-ISA Bridge
00:14.4 PCI bridge: ATI Technologies Inc IXP SB400 PCI-PCI Bridge

So the USB Controller is seen.

family:/home/kai# grep -i usb /var/log/dmesg
[ 0.089885] usbcore: registered new interface driver usbfs
[ 0.089977] usbcore: registered new interface driver hub
[ 0.090055] usbcore: registered new device driver usb
[ 2.238005] ohci_hcd: 2006 August 04 USB 1.1 'Open' Host Controller (OHCI) Driver
[ 15.797635] Initializing USB Mass Storage driver...
[ 15.797657] usbcore: registered new interface driver usb-storage
[ 15.797660] USB Mass Storage support registered.

So it does all that supposedly is to be done. Same grep on syslog,
kern.log, and messages yields no additional information. BUT:

family:/home/kai# ls -al /proc/bus/usb
total 0
drwxr-xr-x 2 root root 0 Aug 6 18:54 .
dr-xr-xr-x 5 root root 0 Aug 6 18:54 ..

and no usb device I plug in is detected (they get power though)...
Where to look next? What other diagnostics to run? Or does anybody know
what I am dealing with here???
Oh: one more diagonstic:
kai@family:~> uname -a
Linux family 2.6.25-2-amd64 #1 SMP Mon Jul 14 11:05:23 UTC 2008 x86_64 GNU/Linux

As ususal: Many thanks in advance!

Best, Kai

Perhaps I'm missing something, sorry? As root, tail -f /var/log/messages,
then plug it in. That's the starting point. Context:

Sorry for the delay in replying.

There are 2 other host controllers you could try modprobing. I remember having
problems with my usb midi keyboard not being detected on one install (Gentoo
IIRC). One host controller was loaded, but I had to specifically load a
different one to get the usb midi keyboard detected. Try the ones below.
ehci_hcd
uhci_hcd

If one of them does result in your usb devices being recognised, add it
to /etc/modules.

btw. You don't have to remove the ohci_hcd, as they don't conflict with one
another.

Sorry for CC'ing you, but your post was a few days ago, and I'm not sure if
you're still reading the list.

Nigel.
