I sent this a couple of weeks ago and got no response... So I try
again. I would really like to see this in the scanner driver, it would
make the lifes of all Sane backend programmers a lot easier. What do
you think?

I agree. Xavier sent me the following patch that does just that. Look

This one's OK by me, though it's "version first" (which I
prefer, Mark's example notwithstanding).

That's up to the current maintainer of the USB

Apparently you did. Your patch works for me, with 2.4.4. David's
slightly improved version works as well.
Thanks, Roman and David, for fixing this!

Perhaps I have a special personal axe to grind with those messages,
but it is _extremely_ irritating to find that important message
disappeared due to dmesg buffer overflow. It happened to me couple

Hello, David!
I've made a patch for devfs support in USB scanners (against 2.4.5-ac9).
It can be found here:
http://www.red-bean.com/~proski/linux/scanner-devfs.diff
The patch is quite straightforward. The changes have been verified against
printer.c and usb-skeleton.c
The scanner names will b
That could be it ... it's hidden appropriately, that's for sure! Great
catch. The TD structures used for ISO have different alignment
requirements than for non-ISO (bigger).
But it's not quite sufficient, the pci_pool alignment requirement
needs to be increased to 32 also (that's what'll really

Ok, thanks to Andries ac9 boots and the printing works fine with it.

Hi,
we have some IBM machines here, they can use USB ethernet via the
pegasus driver, but printing via USB locks the machine.
Numlock works, but sysrq doesnt work.
As soon as it tries to access usblp0 it locks.
I have put some relevant files here:

While running a descriptor dump (code attached) on my USB speakers with
the hiddev ioctl()s in 2.4.5-ac7, I hit the following oops using JE's
UHCI. Repeatable on this HCD, not tried on OHCI or GA's UHCI.

Just a bit of advice really on best practice.
I'm implementing a device where messages on the control pipe are always
followed
by a response. Going through the usb.c code, usb_control_msg
is a legacy function for backwards compaitibilty. I will also not
