[Linux-usb-users] USB problems with Epson Stylus Photo 780

[John Irish]

I am unable to get my Epson Stylus Photo 780 to print reliably using USB with Mandrake 8.1.  The use of the parallel port is unacceptable since it is so slow (I'm not sure what they changed from the older Stylus Color 740 which ran fine on the parallel port).  While text does not seem to produce the error, when printing photos I can't get a whole page printed without the printer hanging (blinking light).   I have to power off the printer to recover.   Any help in resolving this problem would be greatly appreciated.   The following messages are generated during boot:   Jan 30 19:07:16 irish2 kernel: usb.c: registered new driver usbdevfs Jan 30 19:07:16 irish2 kernel: usb.c: registered new driver hub Jan 30 19:07:16 irish2 kernel: usb-uhci.c: $Revision: 1.259 $ time 17:30:17 Sep 23 2001 Jan 30 19:07:16 irish2 kernel: usb-uhci.c: High bandwidth mode enabled Jan 30 19:07:16 irish2 kernel: usb-uhci.c: USB UHCI at I/O 0x6800, IRQ 5 Jan 30 19:07:16 irish2 kernel: usb-uhci.c: Detected 2 ports Jan 30 19:07:16 irish2 kernel: usb.c: new USB bus registered, assigned bus number 1 Jan 30 19:07:16 irish2 kernel: hub.c: USB hub found Jan 30 19:07:16 irish2 kernel: hub.c: 2 ports detected Jan 30 19:07:16 irish2 kernel: usb-uhci.c: v1.251:USB Universal Host Controller Interface driver Jan 30 19:07:16 irish2 kernel: hub.c: USB new device connect on bus1/1, assigned device number 2 Jan 30 19:07:16 irish2 kernel: usb.c: USB device 2 (vend/prod 0x4b8/0x5) is not claimed by any active driver.
