Canon LiDE 100 does not respond after wake from sleep

I have a Canon LiDE 100 flatbed scanner. I constantly put my iMac to sleep and only ever shut it down once every few weeks.
When the computer wakes from sleep the scanner does not respond. Image Capture lists the scanner in the device list but reports the following error;
"An error occurred whilst communicating with the scanner"
I have to unplug the USB cable and plug it back in for it to work (or restart the computer, both always work).
Since I only moved to the Macintosh in July I have no idea how to uninstall drivers to give myself a fresh start and the scanner does not come with an uninstall utility.
Any suggestions on how to fix this little problem?
Thanks.

I am going to respond to my self and say I am nuts.
Canon does not seem to have any uninstaller for this scanner on their site:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDet ailTabAct&fcategoryid=351&modelid=17104
Which is rather odd since they have installers. this is different from most of their other older scanners. But if you just plugged in our scanner and things worked in OSX, which it should have, then you should be OK.
However I can confirm that others see this issue (like my dad) and here is the official Canon response to the issue:
+Dear XXXX:+
+In some cases, coming out of sleep mode may not properly reinitialize+
+the USB bus on Macintosh Operating Systems. Unfortunately, the only+
+work around when this happens is to restart the computer.+
Of course this in not exactly true as logging out and back in fixes it.

Firefox 15 UI does not update after wake from sleep

On my Netbook running Windows XP 32-bit, if I leave Firefox open when I put the computer to sleep (by closing its lid), then when I wake it up from sleep, the user interface elements (like the tab bar) won't respond to mouse clicks. This does not happen 100% of the time; in particular it won't happen for a freshly restarted Firefox that is put to sleep, making the problem rather annoying to reproduce. As far as I can tell, I might have to visit some set of websites with Javascript or Flash or something.
Here are some more details about the user interface, because it is not as simple as non-responsiveness. When I wake it up, when I click on a tab to switch to it, the Windows title bar actually changes to display that tab's page title, but nothing else in the UI updates including the URL bar and the actual page displayed. Similarly for closing a tab; the tab remains, but the title bar shows the title of the tab that would receive focus next. After I "pseudo" close a tab and then restart Firefox, it does not remember that I closed the tab (I save sessions) and restarts with the same set of tabs before I tried to close one.
I get the problem even after disabling all extensions and resetting all toolbars to defaults. I have not tried to create a new profile because I have a lot invested in my current profile.

All applications are not responding when wake from sleep.

All applications are not responding when Macbook pro wake from sleep,
the keyboard and touch pad are okay.
Why?
Thanks a lot.

I want to see if there's a service that may be preventing it from working properly when waking from sleep. To test this, we'll need to Disable all non-system-critical services to see if the issue occurs.
If it does not, that means one of those services that was disabled, is causing the issue.
If the touchscreen is still unresponsive after sleep with all of those non-critical services disabled, then it may be something with the registry or the hardware.
Here are the steps to disable non-critical services:
Windows + Q to bring up Search
Type 'msconfig' and press Enter
Click the Services Tab
Check the Hide All Microsoft Services box
Click the Disable All button
Click Apply and Restart
Once it restarts let it go into sleep mode and then wake it back up from sleep mode and test the touchscreen. Do this a couple of times, if you have time. (When you're done troubleshooting, you'll have to go back into msconfig and re-enable all of those non-critical services, apply and restart.)
Let me know the results when you get a chance, please

WiFi not found after wake from sleep

I have my home wireless network set NOT to broadcast. This should pose no problem once I save it as a trusted wireless network. When I start up my computer and log in, it connects to my home network automatically without any trouble. However, when I wake from sleep it frequently says, none of your trusted wireless networks could be found and I either have to connect manually (by entering the SSID and password) or cycle my airport power off and on 2 or 3 times until it realizes the network is in fact there. The signal strength is very strong (I'm only about 10' away from my router), so that's not the issue. I've seen other macs have the same issue. Has anyone else experienced this or found a solution. It seems like it is giving up on its search of trusted networks before the airport has fully powered on or something. Maybe there's a setting to tell it to rescan a few times before giving up? It's very frustrating.

I finally had the problem once while trying to connect manually. It kept saying connection time out before finally connecting. How does one increase the connection timeout time?

USB devices not working after wake from sleep on WinXP!!! HELP PLEASE!

I would like to put my windows xp to sleep whenever I leave the macbook pro for fear of overheating too much when I'm not using it.
The only problem is that I can't use any more USB devices if I plug them in once I wake it from sleep.
Like my mouse for example, I'm using a laser mouse with a usb plugin but it doesn't respond once I try to use it after WinXP on wake....
Experiencing a ton of wake problems lately...
Sleep is important for a MBP....I hope...

Welcome to Windows. Some devices do not like to be put to sleep in Windows.
There could be driver updates or hot fixes from MS to fix these.
A very proven method (though not for battery life) is to instruct the devices not to go to sleep when the system goes to sleep. You can do this via the device manager in the control panel.
Its not a gracious solution but it will do what you want it to do.

Mouse Not Antialiased After Wake from Sleep? (on external display)

I've been noticing something very strange lately: after waking the MacBook Pro from sleep, the mouse on the screen is no longer antialiased and is instead quite rough looking — it also has no shadow. I've only noticed this when using an external display. If I'm using the MacBook's built-in screen instead this doesn't happen. Not really a huge problem but I was wondering if anybody else had this issue and if there's a fix. Thanks.

I'm sorry, what? Forgive me if I say that your reply doesn't make any sense. This issue almost certainly has nothing to do with the hard drive failing (or being too stressed), nor is it a lack of RAM. In fact, given that it's only with the external display (Apple LED display), it really almost certainly has nothing to do with the hardware it all. Without a doubt, it would appear, it is a software bug of some kind. For example, if I log out and log back in again, it's fine. So, a minor annoyance, but I'm curious if anyone knows about it/knows of a fix.
For the record, I haven't "bell/whistle"d the Finder at all. I don't see how that's relevant in any way, anyway.
I personally speculate this is some sort of bug with Mac OS X; I was wondering if anyone else had had a similar issue.

My Adobe acrobat X Pro does not respond after a minute I open up a pdf file

I recently have installed Adobe Master Suite CS6 Collection. My Adobe acrobat X Pro does not respond after a minute I open up a pdf file. This happens every time when open a new pdf file. My operating system is Windows 7 pro ( Lenovo-64 bits). Any suggestions would be appreciated !!

Mylenium
Thank you for the suggestions.
I checked the WIndows log files. It reported the following error:
The program Acrobat.exe version 10.1.1.33 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.

I ran for the memory diagnostics as it showed the error with video card error. My NVDIA graphics card is not working properly. Do you think that could be a problem?I am running on Windows 7 64 bit computer. It also complains about the incompatibility with 64 bits.
Thank you.

Auto brightness does not work after upgrade from iOS5 to iOS6 on my iPod touch. Is this intended by Apple, or is it a bug?

I attempted to ask this question, yesterday. However, I am not used to typing with my thumbs, yet, and messed it up some. So, I will give this another try. Auto brightness does not work after upgrade from iOS 5 to iOS 6 on my iPod touch. Is this intended by Apple, or is it a bug?

Have you looked at the previous discussions listed on the right side of this page under the heading "More Like This"?
iOS 6 changed how that feature works.

BUG: Sandisk USB flash drive in "half-mounted" state after wake from sleep

My Sandisk Cruzer Crossfire 4GB Flash Drive is left in a half-mounted state after wake from sleep. The Finder believes the drive is still mounted, the icon is on the Desktop. However opening a file on the drive, or trying to eject the drive, results in a long beach ball, followed by a message that I removed the drive without Ejecting it first. The same drive continues to work fine on my Tiger machine, and on PCs.
Bug Report:
Setup:
Macbook 1st Gen (2.0 Ghz)
Mac OS X Leopard 10.5 Clean Install
Sandisk Cruzer Crossfire 4GB USB Flash Drive (in either port)
Repro:
Plug in the drive.
Close the MacBook to put it to sleep
Reopen the MacBook
Result:
The lights on the flash drive never light back up after wake from sleep. Navigating the drive, or trying to eject it results in a "you removed the device without ejecting it first" message.
Expected:
Drive should still be mounted and accessible after waking back up.

It may be a design flaw in the device. Mac OS X does a lot more power management than most other OSes, including tearing devices down to little or no power during sleep. It is possible that the device simply misbehaves due to corrupted memory state or reports a substantially different GUID or something similarly bizarre upon wake. (Okay, that last one wouldn't technically be a power management issue....)
If it doesn't have any problems except when sleeping the system, I would just make sure I unmounted it before putting the machine to sleep and wouldn't worry about it. Maybe check with Sandisk to see if they have a firmware updater for the device.

Left USB-Port dead after wake from sleep. Just restart helps.

I hoped Apples keyboard-Update today would solve my biggest hate-bug in this buggy POS called Leopard. It didn't.
As usual on my Leopard-Macbook Pro, no device will work on the left USB-Port after I waked the computer from sleep. Just a restart helps. I hoped this update to solve this, because it replaced among others "IOUSBFamily.kext".
Terminal gives a timeout error for the internal USB-Hub after wake from sleep. I assumed this should be related.
I'm really angry now.
When will Apple solve the most urgent problems in Leopard?
Was 10.5.1 just smoke and mirrors to make (fool people into...) people upgrade who intended to wait until the first maintenance-update?
Was Leopard Apples attempt to make Windows-Users more comfortable by putting in some heavy extra-bugs and blue screens?
FIX IT FINALLY! And f... don't wait for Macworld to release 10.5.2. It's desperately needed and the current state of Leopard will leave some people very sad at christmas after getting their first Mac. First impression counts and many more peoples first contact with the Mac will be at christmas...

Apple knows the problem and for some reason they are stumped on fixing it. this is so bad I can't believe it. On my macbook pro with Leopard installed, USB left port is dead after sleep. Only restarting can power it back up. I have to restart every day to use my external hard drive for time machine or when putting my flash drive in the port.
Come on already Apple. This is a SERIOUS, SERIOUS problem.
Fix it.

Lid closing does not suspend after update today

...and again: after todays update lid close does not longer trigger suspending my t420s. The last times(!) the cure came always with another update. Please do it again It saves a lot of time.
Thx ahead

I spent a lot of time with reading threads about this topic and I tried all friendly hints and tricks. But I'd never achived a real solution. Everytime it was "magical" fixed with one of the next updates. I guess this happens the 3rd time now. All I want to say is: "thank you for fixing again". For me it's a funny sport after updating: check lid close suspend, check backlight, check bumblebee. I can live will all this tiny issues followed by a fix. That's why I love Arch:)

Finder DOES NOT Respond after Restart, Or Shut Down

I am running an iMac G5 on OS X 10.5.4, After a shut down or restart, Finder does not respond, The only thing on my desktop is My HD and Chosen wallpaper. I can launch Apps from the Dock, but not folders from the dock, Not Downloads folder, Documents Folder, Just Applications, which is weird because they are in finder too! Mail starts up when I log in so I can access Mail, I use Firefox, When I click on it in the dock it starts up no problem, after a while Finder does respond, I get all my icons back on my desktop and can access folders. I have Cleared System Cache, Browsers Cache, I ran Disk Utility and REPAIRED Disk permissions. No help. Short of RE-Installing Mac OS X, What Should I do? Is this happening to anyone else??

I am having the same problem!
I have tried the following: deleting the com.apple.finder.plist, deleting the com.apple.sidebar.plist, I have reinstalled the 10.5.5combo update, I have deleted all of my photoshop preferences (possible solution from another thread), and it is still doing it!

Satellite A65 freezes and does not respond after adding of RAM

Gents,
My laptop Satellite A-65 has been upgrade from 512 MB RAM to 1024 RAM. It recognized additional memory without any problem (as it should be according to manual).
But unfortunately after 1 day it begun suddenly stops, pictures on screen freezes, laptop does not respond at all - only reset (pushing and holding power button) can help. some times laptop is able to work 2 or 3 hours, but then again stops.
Memory place cover is rather hot, fan very often work uninterruptibly. so i can't decide whether problem is in new memory card or not enough cooling or might be in changing of BIOS version (or BIOS setttings) and might be memory becomes full and does not clear itself properly (last remark was found on some forumes).
Experts, help to find exact reason especcially if u had similar problem.

Hi
Im not expert but I would recommend removing the new memory module and let run the notebook only with the standard memory module.
If the notebook will not hang and will not freeze then its a very clear case for me.
Either the second module is not compatible or faulty.
In my opinion you should use branded modules like Kingston for example. The quality is much better as a no-name module.
Additional use the modules recommend by Toshiba
