linux-image-2.6.15-19-powerpc64-smp unable to print to USB printer Lexmark E270

[Jeff Bailey]

From linux-image-2.6.15-19-powerpc64-smp, I am unable to print to a USB printer. I tested a ppc32 machine and it prints to the same USB printer fine.

dmesg reports:
[40583.333551] usb 5-4.2: new full speed USB device using ehci_hcd and address 8

When I attempt to print to the printer, the light will blink, and then stop. No page is issued.

The printer is a Lexmark E270.

The issue seems to be that the ioctl's used for the printer device are not translated between 32-bit userspace and 64-bit kernel.

Not sure if this will get fixed.

I may try to hack on this over the long weekend. Notes from BenC (they may as well be public, posted with consent)

<BenC> ok, in drivers/usb/class/usblp.c
<BenC> there's a usblp_ioctl()
<BenC> it's used in the file_operations struct
<BenC> in drivers/acpi/dev_acpi.c there's an example of an additional compat_ioctl for the file_ops struct
<BenC> any ioctl's that pass data that is the same for 32-bit and 64-bit (typedef'd values like u32, int's, structures that contain compatible members, etc) are just compatible and can be passed directly
<BenC> anything that has incompatible values (long's, pointers, etc) need to be translated

I have the same issue with Epson Photo RX 640.

[10947.431721] ioctl32(usb:16433): Unknown cmd fd(4) cmd(44005001){04} arg(ffb5d246) on /dev/usblp0

Also on PPC-64 and Drapper

This means that we can't use any usb printer attached to our system, so is a blocking bug in my oppinion.

This bug has had no activity for a considerable period. This is a check to see if there is still interest in investigating this bug report.

I still have problems with printing on PPC but are more driver
oriented rather than usb oriented. Upgrading ubuntu to 7.10 solved the
problem for me.

Ok. It appears the reported bug has been fixed in later releases.
Will hold off closing for a while to allow others to comment.
