Hello, I'm having difficulty with usb devices, specifically a camera and a printer - I'm starting to tear my hair out! Problem ONE is that they are not always detected. Sometimes everything goes fine: =======================================================ugen0: Eastman Kodak Company KODAK EasyShare DX4530 Zoom Digital Camera, rev 2.0 0/1.00, addr 3 ======================================================= and =======================================================umass0: EPSON USB2.0 MFP, rev 2.00/1.00, addr 2 ulpt0: EPSON USB2.0 MFP, rev 2.00/1.00, addr 2, iclass 8/6 ulpt0: using bi-directional mode da0 at umass-sim0 bus 0 target 0 lun 0 da0: <EPSON Stylus Storage 1.00> Removable Direct Access SCSI-2 device da0: 1.000MB/s transfers da0: Attempt to query device size failed: NOT READY, Medium not present (da0:umass-sim0:0:0:0): READ CAPACITY.

Sometimes these messages don't show up, but I get this a few minutes after I turn one of them on: =======================================================uhub0: device problem, disabling port 2 ======================================================= Or something like it, depending on where I've plugged it in. I am really not sure what's making the difference, except that it seems never to work if either of them is on when the box boots up, or if I turn on the printer before the camera... but those are certainly not the full story, and I can't pretend to have been exhaustive in testing all the permutations. Problem TWO is with the printer, a nice new Epson Stylus Photo R300, which works beautifully in Windows. In FreeBSD, the camera works fine (with gphoto2 in the command line) once it's detected. But the printer responds very poorly. Doing =======================================================su-2.05b# lptest 20 10 > /dev/ulpt0 ======================================================= makes the printer kind of clear its throat, like it's getting ready to do something, but changes its mind. I've tried sending a line feed afterwards, and pressing all the buttons on the printer, and none of those things seems to help. The machine is supposed to accept US ASCII plain text, according to linuxprinting.org. At least I know I've got the right node, as redirecting to /dev/unlpt0 does nothing at all. Although it seems futile to go further before I've sorted this out, I have tried some spooling stuff. Apsfilter, of course, and there's a proper driver for this printer, print/pips-spr300_310. I've installed that and followed all the setup instructions, configured /etc/printcap with the supplied script... =======================================================su-2.05b# lptest 20 10 | lpr -Pspr300_310 su-2.05b# lpq -Pspr300_310 Rank Owner Job Files Total Size 1st root 0 (standard input) 210 bytes ======================================================= But nothing will happen at all, for ever, not even a throat-clearing. One thing I haven't tried is editing usbd.conf - is there any point doing that in this circumstance? =======================================================su-2.05b# uname -a FreeBSD potato.hogsedge.net 5.3-STABLE FreeBSD 5.3-STABLE #0: Thu Oct 28 14:12:12 BST 2004 root@potato.hogsedge.net:/usr/obj/usr/src/sys/POTATO i386 ======================================================= Here's a bit of dmesg.today: =======================================================uhci0: <VIA 83C572 USB controller> port 0xd000-0xd01f irq 10 at device 4.2 on pci0 uhci0: [GIANT-LOCKED] usb0: <VIA 83C572 USB controller> on uhci0 usb0: USB revision 1.0 uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered uhci1: <VIA 83C572 USB controller> port 0xd400-0xd41f irq 10 at device 4.3 on pci0 uhci1: [GIANT-LOCKED] usb1: <VIA 83C572 USB controller> on uhci1 usb1: USB revision 1.0 uhub1: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub1: 2 ports with 2 removable, self powered ======================================================= and here's a bit of my kernel conf: =======================================================# USB support device uhci # UHCI PCI->USB interface device ohci # OHCI PCI->USB interface device usb # USB Bus (required) #device udbp # USB Double Bulk Pipe devices device ugen # Generic device uhid # "Human Interface Devices" device ukbd # Keyboard device ulpt # Printer device umass # Disks/Mass storage - Requires scbus and da device ums # Mouse device urio # Diamond Rio 500 MP3 player device uscanner # Scanners ======================================================= I'd really appreciate help with this stuff.
