CUPS doesn't see USB printer after being offline 2 weeks
Hi,
I have an Epson R300 printer which had been working with no problems
since its installation at Christmas, but leaving it offline for the
last two weeks or so suddenly has made it show up as "not ready" to
CUPS. I have not had problems before from turning the printer off, and
there is no indication that the USB modules have any problems with it.
The following is what happens when the printer is powered down, then
back up, and an 'lsusb' and /dev/usb check following that...
------

crw-rw---- 1 root lp 180, 0 2005-01-09 12:38 /dev/usb/lp0
hpotter:/home/daddy#
------
Boot up shows nothing different.
There are no errors in the CUPS log, nor anything in any other logfile
either. I cannot get a file to print from the command line. lpq gives
the message that the printer is not ready.
Under X, the CUPS manager (localhost:631) shows the error message
"Unable to open USB device "usb:/dev/usb/lp0": No such device"
Under my kernel configuration being used, I have the following for USB:
------
hpotter:/home/daddy# grep USB /boot/config-2.6.7 |grep -v ^#
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_UHCI_HCD=y
CONFIG_USB_PRINTER=y
CONFIG_USB_STORAGE=m
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y
hpotter:/home/daddy#
------
I really don't know where else to look for clues. Googling gave a few
similar pages (based on that one error message) where the one answer I
saw involved one of the above modules which had to be modprobed. For
me, it's compiled into the kernel.
:(
Can anyone help me with this?
