Please remove hpusbscsi Was: [sane-devel] HP 7450C, hpusbscsi, permissions in Fedora Core 3

[Rene Rebe]

Hi,

we should remove hpusbscsi from the Kernel. It is long obsolete and very 
unstable. I can send a patch for 2.4 and 2.6 (if needed) ;-)

Yes. Hpusbscsi has many drawbacks. The major ones are:

  - does not work with new scanners (that are designed for USB 2.0)
  - it is highly instable (e.g. during an i/o error it locks up
    quite easily and leaves the (usb sub-)system in a state that
    needs a reboot ...

The later problem made me add the user-space i/o code to the 
SANE/Avision backend, because I had to reboot my system every 5 minutes 
during development ...

Yours,

I was waiting for 2.7 to do that. The help file for the scanner carries
a big fat warning. Apparently nobody really cares.

I have reported this to our Mandrakesoft kernel guys, so next 
Mandrakelinux version (10.2) should not have this problem any more.

For now, simply remove or rename the module on your system.

I would rather prefer leaving it in the tree marked as broken than
completly removing the source, for 2.4 at least?
