Comment 219 for bug 85488

If this is fixed in 2.6.21, then it might be worth while for someone to bisect 2.6.20 vs 2.6.21 and see what patch fixed it. Otherwise, we have no idea, and can only guess which of the thousands of patches did it.

Believe me, when I made this decisions long ago, I weighed the options. Yes, it's terrible for you and others like you affected, but the consequences of disabling usb_suspend affects 100% of laptops users, reducing their batter life in the range of 15-60 minutes. Not good at all. I can't justify hurting all laptop users, just to fix a smaller percentage of scanner users.

So, if this is fixed in 2.6.21, then gutsy is going to be ok. If it's wanted in previous editions of Ubuntu, we'll need a specific patch/patchset to regression test for that release.

Again, I apologize if this problem affects you, but it was unavoidable at the time of release.
