[Bug 1114253] Re: system freeze while simple-scan (canon, usb)
Hallo Michael Thank you for responding. The problem is not caused by Simple Scan. Simple Scan supports my scanner perfectly. However both Simple Scan and XSANE can be used to reproduce a USB problem which leads to system freeze. The freeze happens if the scanner is not listed in first position of USB device enumeration.

[Bug 1114253] Re: system freeze while simple-scan (canon, usb)
Hi there, please try a usb 2 port and try xsane, the report back. Also read the following. == Hi there, thank you for filing this bug and showing your interest in Simple Scan! This seems to be a Hardware Issue, i.e. Simple Scan does not support your scanner perfectly -- or possibly not at all. Unfortunately such problems happen more often then they should, and while it might indeed be a problem with Simple Scan, in our experience, most of the time it is not. This is why we prepared a check-list at [1] that will let you find out whether or not it really is a problem with Simple Scan and what your options are in either case. Please read that list and tell us how you decided to proceed. I will set this bug to Incomplete, so a friendly robot will expire this bug in 60 days if you do not respond. However, we would really prefer to hear back from you!
