Did you do "rmmod scanner" before? Otherwise the modprobe does nothing.

Maybe, see below.

Looks ok.
The entries start with "T:" (topology):

Same as above, so it's ok.

Oh, well, this device has three bulk endpoints. two in and one out. I
have never seen this and I'm not sure, if the scanner driver can
handle this.
You should see error messages in syslog if it can't handle this device.
