[sane-devel] Xerox Travel Scanner 100 under Red Hat

There is a chance it's a USB problem.  Some laptops have ports that don't
provide enough power to USB driven devices like this, even though they're
supposed to.

Additionally, my experience has been that with many desktops, the front side
ports will see enough wear and damage (both physical and from static
electricity) over time that they no longer provide a reliable connection.

Typically I recommend using another USB port as far from the original one as
possible on the computer.  Also, if there's a power issue, sometimes a
powered external USB hub will work for you.

The scanner works on another computer with system Windows XP, but don't work
on my computer. I am confused.

In your opinion, may this problem refer to deficiency in power? For example
power unit is lower-power.
