I had the same problem with LM8 and an USB printer.
I ended up fixing it in a roundabout way, since I had problems with IRQ
sharing (a SCSI card and sound card was sharing an IRQ with the USB port,
and the sound card gave me staticly sound, and the SCSI card was giving me
parity errors). I ended up moving my sound card to a different port, and
building a customized kernel from the clean 2.4.4 kernel sources.

Hi,
The only time I could print using the USB port of my printer was during
the installation,
since then trying to use the USB port has locked my system hard more
than once :(
(printing from the // port works fine)
I have added "cups", "usb" and "usbd" to /etc/security/msec/server.4 and
/etc/security/msec/server.5
My cups packages:
cups-1.1.7-1.1mdk
cups-common-1.1.7-1.1mdk
libcups1-1.1.7-1.1mdk
libcups1-devel-1.1.7-1.1mdk
I had a look at:
http://forum.mandrakesoft.com/article.php?sid=944&mode=thread&order=0&thold=
0
but if I try to use printerdrake, first if I create a new printer it
does not ask
on which port I want it (it should at least detect both // and USB), it
seems
to default to USB (that's how ep870_3 was created, see lpstat below) and
when I want
to test it, the machine locks up after 2/3 seconds of printing...
#service usbd status (before printer switched on)
usbd dead but pid file exists
So I restart it...
#service cups restart
#service usbd status (before printer switched on, after restart)
usbd (pid 11139) is running...

note: I have got an external USB drive using "usb-storage" and a USB Web

that work just fine, so the pbm seems to be USB printer specific.
Any help appreciated.
Cheers,
Fred
