papaschtroumpf Posted August 23, 2004 Report Share Posted August 23, 2004 I'm trying to connec t my USB printer (Samsung ML1710 laser) to my mdk 10 OE box. when I try autodetecting in cups, it tells me it found a printer on the parallel port even though nothing is plugged in the parallel port. If I manually enter /dev/usb/lp0 it doesn't work either. I know that particular model of printer is supported by CUPS (it' in the list of printers), So maybe it's just a connectivity issue. Is ther a way to list the USB devices connected to my machine so that I at least know mdk is seeing the printer? The only thing in /dev/usb is "hid" Quote Link to comment Share on other sites More sharing options...

papaschtroumpf Posted August 23, 2004 Author Report Share Posted August 23, 2004 (edited) usbview <{POST_SNAPBACK}> installed it and it tells me it can't open /proc/bus/usb/devices (which it can't because it's not there) so MAndrake didn't properly detct/setup my USB hardware and ports I thought everything was fine becase the hardware wizard sees 2 VT82C586B USB controllers, and the following appears in dmesg: ohci_hcd: 2004 Feb 02 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) drivers/usb/class/usblp.c: v0.13: USB Printer Device Class driver drivers/usb/input/hid-core.c: v2.0:USB HID core driver so I'm not sure what the issue is. Just to be sure, usbview works with the 2.6.3 kernels right? usbview tells me to check that USN is compiled into the kernel (I assume it is in the 2.6.3-7mdk kernel), to make sure the proper modules are loaded (what are the proper modules? how do I know if they're loaded? what aren't they automatically?) and to make sure that usbdevfs is mounted (should ther ebe an entry in my fstab? because there is no usb entry there). who said linux was plug and play again? Edit: I tried plugging a USB thumb drive in the usb port and I don't see it getting automounted to the deskop like it did on a different motherboard. My motherboard is a Shuttle AK35GT2 (KT333 based) motherboard. Edited August 23, 2004 by papaschtroumpf Quote Link to comment Share on other sites More sharing options...
papaschtroumpf Posted August 23, 2004 Author Report Share Posted August 23, 2004 (edited) I had only grep'd for uppercase USB inside of dmesg. If I do a case insensitive grep, here's waht I get: drivers/usb/core/usb.c: registered new driver usbfs drivers/usb/core/usb.c: registered new driver hub ohci_hcd: 2004 Feb 02 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) drivers/usb/core/usb.c: registered new driver usblp drivers/usb/class/usblp.c: v0.13: USB Printer Device Class driver drivers/usb/core/usb.c: registered new driver hiddev drivers/usb/core/usb.c: registered new driver hid drivers/usb/input/hid-core.c: v2.0:USB HID core driver This all looks to me like there is no problem. What am I missing? Do I need to add an entry to usbdevfs in my fstab file? if so, what would it look like?

papaschtroumpf Posted August 23, 2004 Author Report Share Posted August 23, 2004 ohci_hcd: 2004 Feb 02 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) <{POST_SNAPBACK}> if I do an lsmod I see "usbcore 99132 4 hid,usblp,ohci-hcd" Trying to read up on USB, it seems that VIA based boards should use the UHCI and not OHCI driver (by the way I lied in my post above, it turns out my motherboard is based on the KT266A). why did Mandrake install the OHCI driver then?

Steve Scrimpshire Posted August 23, 2004 Report Share Posted August 23, 2004 I don't know but I had to change mine too. This is what my current line in /etc/modprobe.conf looks like: install usb-interface /sbin/modprobe usb-uhci; /sbin/modprobe ehci-hcd; /bin/true Try changing that and reboot.

kmc77 Posted August 24, 2004 Report Share Posted August 24, 2004 I worked on mine for a month, then gave up and used parallel cable to connect. Worked immediately. Wish I could give you better advice, but that's the only way I could get my printer to work. (I know, I know - I took the easy way out :P ) Quote Link to comment Share on other sites More sharing options...
papaschtroumpf Posted August 24, 2004 Author Report Share Posted August 24, 2004 no parallel port on my printer :P I'm thinking about doing a full re-install though: I swapped the motherboard a few weeks ago without doing a full re-install and it might explain the wrong usb type issue (the previous board was based on a SiS chipset, not VIA). There are other worrysome symptoms too: lsmod shows that both via-agp and sis-agp are installed. Quote Link to comment Share on other sites More sharing options...
