epson usb printer

I've just bought an EPSON STYLUS COLOR 580 printer and a pci card to plug my usb-printer on, since I had no usb port.

FIRST, using Printerdrake, i've set the printer on /dev/usb/lp0 , and then Cups understands it right.
Trouble arises at this point : I can't print anything !!!!!!

I read some advice on the forum, and here is the result*:

1) /proc/bus/usb/devices
-> it's empty !!!

2) /.../rc.modules
-> i've added : modprobe printer (shouldn't I also load usb-hci ?)

3) lsmod :
printer 3956 (unused)
usbcore 43632 [printer]
…

4) dmesg :
usb.c : registered new driver usbdevfs
usb.c : registered new driver hub
usb.c : registered new driver usblp
-> it looks like there's no bus number assigned and no port detected

5) lspcidrake :
OPTi Inc.I82C861 (SERIAL_USB usb-ohci) Subvendor=0*10456 Subdevice=...
-> I can't see the printer in /dev/usb/lp0

6) cat something > /dev/usb/lp0
-> I had something like "no such peripherical device"


I can't understand everything, but hope it will help you to telling me what happens.

Do "modprobe usb-ohci" and see if that helps, if it does, add it to rc.modules.

Though I did modprobe usb-ohci, it won't work. Many changes I noticed :

1) lsdev :
Device : usb-ohci, DMA: /, IRQ:11, I/O ports: /
-> there's no port ?

2) lsmod :
usb-ohci 12624 0 (unused)
usbcore 43632 1[uxb-ohci printer]

3) demesg :
usb-ohci.c: usb ohci at membase 0*c6098000, IRQ 11
usb.c : new Usb bus registered, assigned bus number 1
usb.c : USB new device connect, assigned device number 1
usb.c : USB new device connect, assigned device number 2
printer.c : usblp0 : USB Bidirectional printer dev 2 if 0 alt 0

4) cups :
-> the printer didn't react at all. and the device /dev/usb/lp0 is still unknown. (cups tells me : "unable to open usb port device file : no such periqheical device")




Could someone also tell me how to configure cups options ? Each time I start Kups, I can read "can't connec to cups server, check your options" . The only way to have it right I found is to run printerdrake once (then , I can print on a parallel-port-printer). My options are :
- user:root
- cups host : localhost
-cups port : 631
- cups configuration file : /etc/cups/cupsd.conf
Where can I find an example of a configuration file ?

There are three different usb chipset drivers, exactly which one to use depends on the chipset on your motherboard. If you can post the motherboard make and model I should be able to tell if usb-ohci is the correct module or weather you should be using another one.

It's a dual-pentium PCI-ISA Bus Mainboard . The model is Ga-586DX, but it's without a usb port!

I've added a pci card to plug my printer on : I con read on it :
-> <CF> 04V0 94V-0 E119801
-> CE 1051P
-> Made in Taiwan FCC : H9MSER40XX VER:2.0
And on the chipset itself :
-> OPTi
-> FireLink
->82C861
-> 140119
-> 10UE
That's all...

Aha..an add on usb card..do "cat /proc/pci" and post the details of the usb card.

I did a cat /proc/pci :

Bus 0, device 10, function 0:
USB Controller: OPTi Unknown device (rev 16).
Vendor id=1045. Device id=c861.
Medium devsel. Fast back-to-back capable. IRQ 11. Master Capable. Latency=32.
Non-prefetchable 32 bit memory at 0xe1004000 [0xe1004000].

Ok the OPTi cards use OHCI, do "modprobe usb-ohci" then try the printer.

thanks.

I recently solved my problem by thinking a little bit : 'I' must be wrong somewhere...(everything looked all right)
I was. I had just to turn on my printer before launching linux.
