ehci-hcd.ko (aka ehci_hcd) fills /var/log/messages

[mikeward]

I'm running Fedora 8 (with all current updates) on an HP Pavillion computer.
When the ehci-hcd.ko module is loaded (at boot) it fills my /var/log/messages with:

Jan 4 11:52:15 localhost kernel: usb 1-4: new high speed USB device using ehci_hcd and address 58
Jan 4 11:52:15 localhost kernel: usb 1-4: new high speed USB device using ehci_hcd and address 59

Jan 4 11:52:17 localhost kernel: usb 1-4: new high speed USB device using ehci_hcd and address 68

4 lines every second.
In order to stop this I had to remove the module from corresponding initrd img:
. mkdir /tmp/initrd
. cd /tmp/initrd
. gunzip < /boot/initrd-2.6.23.9-85.fc8.img | cpio -i --make-directories
. rm lib/ehci-hcd.ko
. find . | cpio -o -c | gzip -9 > /boot/initrd-2.6.23.9-85mw.fc8.img
. chmod go-rwx /boot/initrd-2.6.23.9-85mw.fc8.img
- rename /lib/modules/2/6/23/9-85.fc8/kernel/drivers/usb/ehci-hcd.ko
so that it won't reload

This seems to fix the problem, but I imagine I'm going to want a working ehci-hcd.ko at some point.
Does anyone have a clue about what is going wrong or how to make ehci-hcd.ko work proplerly?

Thanks,

I have two pieces of equipment plugged in to usb sockets. One is the HP 22-inch LCD color monitor that came with the computer. The other is the HP Photosmart C4180 All-In-One printer/scanner/copier.

I booted kernel 2.6.23.9-85 with the echi-hcd.ko module loaded, this time without HP monitor or printer plugged into usb ports. The ehci_hcd driver did not go crazy with messages. When I plugged the HP monitor into a usb port, then the HP printer/scanner/copier, no streaming messages into the log:

The removable disk (sdf) must be for the memory card reader on the printer. When I try to mount it, it says there is no media.

[root@trivector mike]# mount -t vfat /dev/sg6 /mnt/usbhd
mount: /dev/sg6 is not a block device
[root@trivector mike]# mount -t vfat /dev/sdf /mnt/usbhd
mount: No medium found

The problem must be due to booting the computer with the devices plugged in. I suspect the HP All-In-One printer/scanner/copier. It looks like the problem can be avoided by unplugging the printer before booting. However, that means leaving it unplugged when not in use. Otherwise, a power outage might cause my disk to fill up with log messages. Not exactly ideal either way.

[bradchaus]

have you tried unplugging any of those devices to see which one causes the problem? ...
