Scanner

[Alfred]

I checked in Synaptic, and these Utilities were already installed.
Scanbutton I added. I also added USBVIEW, it allows you to see what is
happening with USB. sane-utils was there already.

I'll try out the Commands you gave in Terminal mode. It recognized the
scanner, in both cases, as is, but could not open it or get it to work.

Analog things work intermittently, Digital things either Work or they
don't!

Alfred!

Hi William

I don't have an answer but I am having the same sort of trouble. Is your error message something like this:

Failed to open device 'snapscan:libusb:005:002";
Invalid argument

This apparently is a usb bug in the kernel, introduced after Edgy.

If you google:

Failed to open device 'snapscan:libusb

You will get many results.

I read on an Ubuntu help page that we are supposed to install scanbutton 
as a workaround.

Now I can't find the link. It did not work for me.

If you have not done so, why not install:
sane-utils

You can run these commands just to make sure it's being found and so on:

$ sane-find-scanner
found USB scanner (vendor=0x04b8 [EPSON], product=0x0122 [EPSON
Scanner]) at libusb:005:002

$ scanimage -L
device `snapscan:libusb:005:002' is a EPSON EPSON Scanner flatbed scanner

I posted to the sane list about this on Friday. I am still waiting to 
hear back. My problem may not only be Kernel oriented. Under Edgy my 
scanner only worked some of the time. I used it on a dual boot box. If 
it was not re-initialized under it's native software in Windoze every so 
often I found i would get this error too.

I wish I had more to offer. I will let you know if I hear back from the 
sane list-Patrick
