Well, since I don't use P&P, I just look at the error messages at boot
when it tries to load the module (I've played around with the modules).
There is some error message - I forgot what it is - but the end result
is the reader doesn't exist. I'm using the 2.4.32 kernel, so guess this is
why I need to look at /proc/scsi/usb-storage to see the status of my
functional reader (I don't have a /proc/bus/usb). Looks like 2.0 to me.
Maybe the reader is just defective. I might see if it works on a friend of
mine's Windoz computer. My RadioShack one works fine.

Hello,
well, a simple thing, when devices are plugged:
dmesg|grep 'speed USB'

For me, this shows:
usb 2-2: new low speed USB device using ohci_hcd and address 2
usb 2-3: new low speed USB device using ohci_hcd and address 3
usb 2-4: new full speed USB device using ohci_hcd and address 4
usb 1-5: new high speed USB device using ehci_hcd and address 5
usb 1-6: new high speed USB device using ehci_hcd and address 6
The little code 2-2, 2-3, ... matches the Bus-Device couple.

I have:
2 low speed USB devices (USB 1.x) +
1 full speed USB device (USB 1.x) +
2 high speed USB device (USB 2.x).

lsusb gives the details of each devices, ordered by Bus-Device couple.

Thierry MERLE

Why four copies of the same message?

Apologies for that, my newsgroup reader told me errors whereas the

Quite likely because you're using an email client which (sort of) happens
to (sort of) work with newsgroups too. Sounds like a good time for an
upgrade to a real newsreader.

Right, simple and dedicated is the best
