I'm pretty sure that my printing problem is really a USB problem, so I looked for some USB specific log and didn't find one. Then I looked for some utility to debug what's happening to USB ("linux debug usb" on GOOGLE), but all I found seemed to be tools for developers (for instance to reverse engineer USB Windows device drivers). Can anyone suggest something to try and see what's going on here?
BTW - I've included more info below. I **think** everything looks normal, but maybe someone sees something wrong here. the following lines are from dmesg usb-uhci.c: USB UHCI at I/O 0xd000, IRQ 10 usb-uhci.c: Detected 2 ports usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 2 ports detected usb-uhci.c: v1.275:USB Universal Host Controller Interface driver usbdevfs: remount parameter error usb.c: registered new driver usblp printer.c: v0.11: USB Printer Device Class driver hub.c: USB new device connect on bus1/1, assigned device number 2 hub.c: USB hub found hub.c: 4 ports detected hub.c: USB new device connect on bus1/2, assigned device number 3 usb.c: USB device 3 (vend/prod 0x55f/0x6) is not claimed by any active driv er. hub.c: USB new device connect on bus1/1/2, assigned device number 4 printer.c: usblp0: USB Bidirectional printer dev 4 if 0 alt 0 proto 2 vid 0 x04B8 pid 0x0005 the following lines are from /var/log/kernel/info Dec 28 20:22:59 shlomo1 kernel: usb.c: registered new driver usbdevfs Dec 28 20:22:59 shlomo1 kernel: usb.c: registered new driver hub Dec 28 20:22:59 shlomo1 kernel: usb-uhci.c: $Revision: 1.275 $ time 18:49:04 Sep 20 2002 Dec 28 20:22:59 shlomo1 kernel: usb-uhci.c: High bandwidth mode enabled Dec 28 20:22:59 shlomo1 kernel: PCI: Found IRQ 10 for device 00:07.2 Dec 28 20:22:59 shlomo1 kernel: PCI: Sharing IRQ 10 with 00:0b.0 Dec 28 20:22:59 shlomo1 kernel: PCI: Sharing IRQ 10 with 00:0c.0 Dec 28 20:22:59 shlomo1 kernel: usb-uhci.c: USB UHCI at I/O 0xd000, IRQ 10 Dec 28 20:22:59 shlomo1 kernel: usb.c: new USB bus registered, assigned bus number 1 Dec 28 20:22:59 shlomo1 kernel: hub.c: USB hub found Dec 28 20:22:59 shlomo1 kernel: hub.c: 2 ports detected Dec 28 20:22:59 shlomo1 kernel: usb-uhci.c: v1.275:USB Universal Host Controller Interface driver Dec 28 20:22:59 shlomo1 kernel: usb.c: registered new driver usblp Dec 28 20:22:59 shlomo1 kernel: printer.c: v0.11: USB Printer Device Class driver Dec 28 20:22:59 shlomo1 kernel: hub.c: USB new device connect on bus1/1, assigned device number 2 Dec 28 20:22:59 shlomo1 kernel: hub.c: USB hub found Dec 28 20:22:59 shlomo1 kernel: hub.c: 4 ports detected Dec 28 20:22:59 shlomo1 kernel: hub.c: USB new device connect on bus1/2, assigned device number 3 Dec 28 20:22:59 shlomo1 kernel: hub.c: USB new device connect on bus1/1/2, assigned device number 4 Dec 28 20:22:59 shlomo1 kernel: printer.c: usblp0: USB Bidirectional printer dev 4 if 0 alt 0 proto 2 vid 0x04B8 pid 0x0005 Dec 28 20:22:59 shlomo1 kernel: Adding Swap: 128484k swap-space (priority -1) Dec 28 20:22:59 shlomo1 kernel: Adding Swap: 248968k swap-space (priority -2) Dec 28 20:22:59 shlomo1 kernel: usb.c: registered new driver usbscanner Dec 28 20:22:59 shlomo1 kernel: scanner.c: 0.4.6:USB Scanner Driver the following lines are from /proc/bus/usb T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 4 Spd=12 MxCh= 0 D: Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=04b8 ProdID=0005 Rev= 1.00 S: Manufacturer=EPSON S: Product=USB Printer S: SerialNumber=HK0120002171047350 C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 2mA I: If#= 0 Alt= 0 #EPs= 2 Cls=07(print) Sub=01 Prot=02 Driver=usblp E: Ad=01(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms here are my usb devices [root@shlomo1 usb]# ls -la /dev/usb total 0 drwxr-xr-x 1 root root 0 Jan 1 1970 ./ drwxr-xr-x 1 root root 0 Jan 1 1970 ../ crw-rw---- 1 lp sys 180, 0 Jan 1 1970 lp0 crw------- 1 solomon root 180, 48 Jan 1 1970 scanner0 -- Shlomo Solomon http://come.to/shlomo.solomon Sent by KMail (KDE 3.0.3) on LINUX Mandrake 9.0 ================================================================To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
