Scanner

[Alfred]

Thank you Patrick:

I spent the day, going to a friend and getting all the Patches on top of
Patches on top of Patches, for my Win 2K, that can run Serif Software,
Never Got Serif Web Plus 10 to run in Linux yet. 

Then in the evening I replaced my Thermaltake beetle with a Thermaltake
Volcano 7 Cooler, because I think the refrigerant leaked out of the
Beetle, the CPU was running at 98 Degrees all of a sudden. Now it is
running at 82 degrees, with the Fan going at 6,200 rpm. It does not
sound like an Avro-Arrow taking off!

Tomorrow I'll have some time to look at it again. So I can see what you
are talking about and I'll try to download those tools, you are talking
about.

This Friend Downloaded GEbuntu it looks nice, a bit hard to read the
Icon writing, but it looks nice.

Alfred!

Yup - That's it! It appeared like that for other scanners too.

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
