In case it may be of any assistance in dealing with my
problem, I take the liberty of including now the
entire output from "cat /proc/bus/usb/devices":

I'm sure it's unnecessary for me to say so, but my
knowledge of these matters is rather glancing.
I ran the command "/sbin/lsmod" and got a list of my
loaded modules. There isn't one called "usbcore". The
command "/sbin/lsmod | grep usb" produces the
following output:
"[EMAIL PROTECTED] ~]$ /sbin/lsmod | grep usb
usb_storage 68489 1
scsi_mod 140073 2 sd_mod,usb_storage
snd_usb_audio 65025 2
snd_usb_lib 13121 1 snd_usb_audio
snd_rawmidi 28641 1 snd_usb_lib
snd_pcm 99657 4
snd_usb_audio,snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd 56741 13
snd_usb_audio,snd_rawmidi,snd_seq_device,snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
[EMAIL PROTECTED] ~]$"
The output of the command "/sbin/lsmod | grep core" is
as follows:
"[EMAIL PROTECTED] ~]$ /sbin/lsmod | grep core
i2c_core 21953 1 i2c_i801
soundcore 10785 3 snd
[EMAIL PROTECTED] ~]$"
I knew, however, that I'd seen the word "usbcore"
before when examining the output of "dmesg", so I ran
that for the purpose of this post and got the
following output:
"[EMAIL PROTECTED] ~]$ dmesg | grep usbcore
usbcore: registered new driver usbfs
usbcore: registered new driver hub
usbcore: registered new driver hiddev
usbcore: registered new driver usbhid
usbcore: registered new driver snd-usb-audio
usbcore: registered new driver spca5xx
usbcore: registered new driver usb-storage
[EMAIL PROTECTED] ~]$"
I googled for "usbcore module", but got no assistance
for present purposes.
Is it possible that some other loaded module has a
parameter which, when set appropriately, would provide
the equivalent output?
Finally, assuming I had usbcore, am I right to think I
could set the parameter by doing this:
echo "y" > /sys/module/usbcore/usbfs_snoop
I apologise for not being able to do more to help
myself. I appreciate very much your taking the trouble
to reply to my original post.
Best wishes,
Leslie
