Espon printer not detected as a usb device

[dogdo]

Hi

I have a Epson Stylus SX115 All In One Printer which i connected to ubuntu 9.10 the other day. Upon installation the drivers for the stylus SX 115 were not available, but there were drivers for the stylus SX110 which i then installed. Printing is fine although for some reason even though i connect via usb cable the printer is not detected as a external device. I have to pull out the usb cable without unmounting-what should i do?

Is it listed in lsusb?

I'm guessing that because it's not a disk device it doesn't need safe removal.

Is lsusb a sudo command? But the printer connects via usb -should it not have to be mounted/unmounted?

lsusb is a terminal command but it doesn't need sudo. Run it and post the results.

"Mounting" means attaching a filesystem found on a device to a particular directory (mount point) in your directory structure. You can't really "mount" other kinds of device.

And the reason "unmounting" matters is that some writes to a disk are cached and not written immediately. Unmount, eject, safely remove etc make sure those caches are fully written.

I don't see how any of this applies to a printer. The worst that can happen if you pull the plug is that you lose a print job - you would never leave the printer in an inconsistent state where it can't be used again.

So I don't think you have anything to worry about. :)

Ok here is lsusb on my pc without any any devices attached via usb:

Oh god...what is going on? what are all these errors?

:D It looks like you pasted the output of the previous command in, instead of typing lsusb again!

Attach the printer and type lsusb at the command line

Ok this is what i got from running that sudo command once with the printer:

shinji@shinji-laptop:~$ lsusb

So your Epson is detected as a usb device!


So I don't think you have anything to worry about. :)

Ok so my printer does not have a file system on it-therefore not mounting/unmounting will not damage the printer or pc.

You''ll have to forgive my slowness..have been using windows for years so the idea of not 'safely removing a device' is so new to me.
