Hello.
I have got a Compaq Presario 907EA. Here's my lspci info:

Recently, I've been trying to get the USB working. The usb-ohci module seems to load nicely with my 2.4.21 vanilla kernel, and when I have a Logitech Quickcam Express connected I can get some info in /proc/bus/usb, which I think is a good sign. The problem is, whenever I load the usb-ohci module, my ethernet card stops working! I have been looking in the usb documentation included in the kernel source package, linux-usb.org and the linux-hotplug sites but can't find any solution to this.
Normally I have these modules loaded:
| Code: | bash-2.05b# lsmod
Module Size Used by Not tainted
rtc 6940 0 (autoclean)
usbcore 62944 1
trident 28852 1
ac97_codec 11880 0 [trident]
8139too 15240 1
mii 2528 0 [8139too] |
After loading usb-ohci, /var/log/messages contains these messages:
| Code: | bash-2.05b# cat usbprob-messages

At least the kernel says something is wrong! The last two messages keep repeating themselves over and over, but the one about half-duplex mode is nothing to bother about, I've always got that one (I guess it has something with either my NIC or the other end (?) )
Well, this post became rather lengthy, hope you people could help me out!

The problem is solved!
I simply changed to vanilla kernel 2.4.22! Don't ask me why, but now the ethernet card and the webcam can work together, which is kind crucial (w-e-b-cam). I remember reading that the 2.4.20 kernel didn't support the Presario 900 USB system, but apparantly the same holds for 2.4.21.

You can bet your ass it was an IRQ issue.
Maybe the newer kernel just likes your chipset more and routes the IRQs correctly... |

sounds reasonable, obviously the two drivers "collided"
but now I'm happy!
