The situation in Mandrake 8.2 is the following:
- It does not contain the tweaked printer.c module.
- printerdrake uses HPOJ automatically for all the printers listed
below as not out-of-the-box working with USB except the HP LaserJet 2200.
So the problem should not appear for users of Man

Hi!
Anyone had any luck using an Imation Superdisk under linux? Have tried for
a while now, but I can't get it to work. I am using kernel 2.4.18.
The
device is found, but when I try 'cat /proc/scsi/scsi ' the machine
hangs...
Very grateful for any help I can get.
Regards,
Fredrik Hegardt

In short, device drivers don't do allocation, that's done
inside the HCDs ... :) And only for periodic URBs.

Hi,
This is an updated version of a patch I sent around a
while back. It's against 2.5.7-pre1 (so presumably is
fine on 2.5.7), and addresses feedback against that
earlier patch.
It's bugfixes, mostly for highspeed support, to what
/proc/bus/usb/devices shows:
- Shows isochronous periods corre
I've used one for several months now with no problems.
What does dmesg say? How do you know that "the device is found"?

See the note below, which I can hope will explain enough
of the details for someone to fix it.
There are enough other things on my queue that I'd really
like someone else to fix this ... :)

No problem for Mandrake 8.2, it automatically installs HPOJ for these
devices. So the only printer which would not work out-of-the-box with
Mandrake 8.2 is the LaserJet 2200 on USB.

Not quite, here's a small patch I added to explain the 'E:' format

Hi,
I have a Cannon N650U scanner which, as far as I can tell from what I've
read so far, is not supported under Linux. Does anyone know of any
development work being done for this device before I start thinking
about jumping in.
It appears from the comments in scanner.c (0.4.7) that people a
Hi!
I bought a DMI USB 2.0 Storage Adapter and I need some hep with getting
it working.
Could somebody help me?
My plan is to try drivers for some other devices or use usbsnoopy.
But maybe someone have valid hints for me, maybe it is similar
to existing devices and I have just to add something
