Sleep issue and USB 2.0 card

I recently installed an Allego 2.0 USB card, recommended by Apple, into my G4 1.25 Dual. The card works great but now I cannot put the computer to sleep. Whether by button or command the monitor goes dark but the G4 is still awake plus I can't bring it back without a cold boot. Tech support said this was an issue, offered some tips and said if all fails get a different card. I bought Iomega's as an experiement and same problem! Anybody else have this issue and could you solve it?
Thanks.

Hi Joe,
Yes, my mac usually sleeps just fine. My own sleep is another issue but that is for another forum.
A couple of years ago I was on another forum and saw a post claiming a fully functional usb2 card for $9. I bought it and it worked slick as could be. It was a no name, no box, no instructions, bare card but the price was good and it came with a usb2 cable. I then posted as many times as I could to others about that site and the card. About a year later the link broke and I went back to the site. The had a card that looked the same, had the same chipset, and was the same price but the manufacturer had changed some components. The second card did not work as well as the first.
Since then the same thing has happened to all of the makers of usb 2 cards. Something on the card changes and breaks sleep. It's not your fault. It's not the vendor's fault, it is the manufacturers fault. By the way, the manufacturers are usually not the name you see on the box. Companies buy from a manufacturer and slap their lable on the box.
Keep trying and you will eventually find one.
One guy went so far as to pay Belkin extra money for one of the older cards but it worked.

  • More no sleep issues and sleep troubleshooting

    My one year old 20" Intel iMac Core 2 duo has just started not scheduled sleeping (will sleep when directed though...you know what I mean)...this really makes me mad because it's so hard to fix. I had this happen on my old G5 iMac and it took a month and two visits to the Mac geniuses to figure out. Anyway here are the things I tried with direction from this board and an Apple CS rep. (still no joy):
    -removed all USB and firewire devices except keyboard and mouse
    -made sure bluetooth is turned off (i had a bluetooth mouse that used to wake up my old G4 iBook)
    -made sure that windows sharing is off as well as printer sharing and personal file sharing (even though OSX is perfectly capable of sleeping with printer sharing and personal file sharing on while other computers are not connected. Not so with Windows file sharing on in my experience)
    -internet sharing off
    -reset PRAM
    -reset SMU
    -deleted cache
    -repaired disk permissions
    -booted from install disk and repaired disk (no repairs were necessary according to disk utility)
    -trashed preferences file (ouch, this really ***)
    -created new user account to test and still won't sleep
    -booted in safe mode (sleep works!!!!! but only in safe mode)
    These are the thing's I've tried...if there's anything any one can recommend on top of these please reply. Since this has been such a pervasive problem with non-laptop Macs I'd really love to see a troubleshooting flow chart for these sleep issues. I'd write it myself if I could get some guidance on which procedure to try first and so on...
    Dennis (den.thed) seems to be the sleep guru. If you've got time to weigh in I'd appreciate it before I format my HD and start from zero day.

    One thing that work for me was the following: I did all the hints possible but nothing worked until I decided to look at the Console logs, something was preventing the system from going to sleep, I looked at the logs and I had a repeating message: "com.apple.nis.ypbind: domainnname not set. aborting...throttling respawn:will start in 10 sec" it means its an active process. In fact there is a thread here that points toward this message. The message went away with the following fix: in Terminal I typed: sudo domainname example.com ,upon entering I noticed that the Console messages stopped immediately. So the next step was to observe if the computer would sleep on its own and YES it did.
    So this may not fix your sleep issues if there is another process involved, but I think the symptoms are very similar. I have also read that some caches folders are corrupt (if upgrading from Tiger) and since repairing permissions is a whole 'nother story these may not be purged at all thus causing conflicting processes and misdirected maintenance scripts that run in the background. If anything new I will kee posting. hope it works

  • Sleep issues and Ethernet

    On my fp iMac, running 10.4.11:
    A relatively new (roughly the past ten days) issue has arisen. I think I've narrowed it down to when the machine is woken up from sleep. I can't get on the internet nor can I connect to my other two machines from the 'Go > Connect to Server ...' command. A restart seems to temporarily sort the problem out.
    System Preferences exhibits odd behaviour when I go to the Network Pane while being cut of from the internet. This machine is connected to an Airport Extreme Base Station via Ethernet cable. In the Network Status window, the Ethernet button is red instead of green, and the following message is displayed:
    +The cable for Built-in Ethernet is connected, but your computer does not have an IP address and is not connected to the internet.+
    When I try and close the System Preferences window, I get the spinning beach ball. I have to use Force Quit twice in order to quit System Preferences. It's at this point I do a restart.
    In the past week I've used OnyX, DiskWarrior (twice), I've shut down and unplugged the AEBS and the broadband modem overnight as well as shutting down the computer, and yesterday I reset the PMU - almost in desperation. Two days ago I downloaded and installed the 10.4.11 combo updater.
    At present I've got the machine set to screen sleep only, no hard disk sleep.
    When it was set with hard disk sleep as well, it seemed that all was well until a few hours of normal use (including being woken from sleep) had passed before the problem arose.
    I might be wrong about sleep being an issue, but certainly the behaviour from System Preferences > Network is consistently the same.
    Can anyone shed some light here?

    Ok for the sleep issue the link from fishcomputer has some steps in for these type of issues but there something that more then likely is causing isssue with sleep.
    I would try the following
    Remove the powermanagement.plist located in mac hd/ library/ preferences/ systemconfiguration/com.apple.powermanagement.plist  delete that then restart
    For Microsoft issue i would try the following
    Boot into safe boot by holding shift at startup until you see apple and gear may also see loading bar once in safe boot remove the following folders
    MacHD/System/Library/Caches
    MacHD/Library/Caches
    User library Caches and cookies folder
    Restart.
    Since you are in lion you can't remove the folders from Hd need to just remove contents of the folder

  • Sleep issues and strange message in console

    Hi all,
    For the last month or so, the only way to sleep my Mac Pro is via the apple menu, it won´t sleep automatically as programmed by system preferences. I have read other posts, and the only solution seems to be the use of PleaseSleep, right?
    I also have this console message every time I wake the computer or display from sleep: "loginwindow[48]: in pamsmauthenticate(): Failed to determine Kerberos principal name"
    Does anybody know if this could be related to the sleep issues?
    Thanks in advance

    Hello:
    Your English is excellent...far better than some who claim it is their mother tongue
    My answer was a bit flippant, sorry
    I looked at my own logs after reading your last post.  I note all sorts of incomprehensible (to me) messages - some indicating errors.  I have no clue what the sandbox messages indicate.
    The other problems could be caused by a number of things - including hardware problems.
    You might try resetting the PRAM and SMC.  Those are not cure alls, but they cannot hurt anything either.

  • Controling heating/cooling element with labview and usb 6008 DAQ card

    Greetings All
    I'm looking for a heating/cooling type of element that I can control with labview and my usb-6008 card. Heating/Cooling will just be for clean water and the temperture range will be from 0 C to 100 degree C.
    Thanks
    The heating and cooling elements can be seperate products. Any recommendations

    A simple kettle element will of course be sufficient for upto 100°C
    To get the temperature down you need a cooling system, what springs readily to mind of course is a refrigerator.
    Just a note of warning, water and electricity are dangerous bed fellows.
    On that note perhaps one of those vortex air units would be safer - they blow hot in one direction and cold in the other, nominally to 100°C

  • Sleep issue and hard disk tick?

    I have been noticing a single tick everytime i put my iMac to sleep manualy. Also a while after it does it again about twice in a row (maybe when it is done falling asleep completely? lol)  Anyways, this bothers me since it is a brand new 27 inch iMac and I fear it has a hardware problem. I dont exactly know when it started, or even if it has been doing it a lot. But it came to my attention when i started diagnosing my computer on a dialy basis to make sure everything is ok. Now, I also have this problem with a WD Passport External HD. When I connect it to my iMac it recognizes it just fine, but sometimes out of nowhere it starts beeping and when I try to open it from the iMac, the beach ball starts spinning untill i eject it. Notice that this does NOT happen when i connect it to a windows computer. At least i havent noticed. And this is a little strange, but when i grab the HD and flip it, it STOPS beeping! and it goes on to do the usual time machine backup. I bring this issue up because i read somewhere that the external hd could be causing the tick as i put my iMac to sleep, and also because it bothers me how it only has happened to me in this iMac and not on my parents windows computer. Maybe a compatiibily issue? Also i would like to run a hardware test but I cant seem to find an option. Thanks everyone! I hope i can resolve my problem without having to take my computer to an apple store.

    By the way, other than this two issues, my iMac seems to be completely fine, exept for the fact that when i wake the iMac from sleep it makes some type of humming noise as if it was booting up (someone tell me if this is normal) and it also tells me that it couldnt find my network but at the same time i go on safari and can use it just fine. Weird

  • Sleep issues and failure code 0x00000200 0x11000000

    hi.
    I was wondering if anyone could shed some light on this error please.
    I tried to wake my imac tonight and I was unable to and had to hold the power button to restart the computer, I have notice in the console log this error in the log.
    Sleep failure code 0x00000200 0x11000000, Previous Shutdown Cause: 3 and BSD root: disk0s2, major 14, minor 2.
    Any ideas? I might have to start shutting down my imac in future despite clearing out the SMC the other day.
    I am running 10.6.1 snow leopard

    Thanks for the message. This has happened a couple of times but this only happens when I switch user and the click on the sleep button on the login window. However I am running a hardware test and the quick one came back all ok. I am now running an extented one and will report back.
    If it is a memory error I will see a genius my imac is still in warranty I don't have AppleCare as I thought it was not worth it. I am thinking it might be a software bug like what was reported if you have the guest account And then finding all your files deleted.
    Any ideas?
    Thanks

    Is the address on your iTunes account exactly the same (format and spacing etc) as on your credit card bill : http://support.apple.com/kb/TS1646 ? If it is then you could try what it says at the bottom of that page :
    If the issue persists, contact your credit card company and verify that they and any company they use to process credit card authorizations have the correct information on file.

  • Still no fix for USB card sleep Issue

    Hi I just bought a 3rd party USB 2.0 card (an IOGEAR GIC251U). When I plug my LaCie extrenal USB drive in it works fine, until the computer has been to sleep. When the computer wakes up the drive has disappeared and I get a message saying that the drive has been improperly disconnected and that I can damage it by not ejecting before disconnecting.
    Looking at the posts on this forum, it seems that this PCI USB card sleep issue is a persistant problem. I have even heard buying a card described as a "crap shoot".
    That is not an acceptable answer to me. I insist that Apple reccomend a USB 2.0 card that it is willing to garuntee will work with my mac (an AGP G4 blue and white tower). If not, how can Apple in good faith sell computers with PCI that isnt equipped to handle built in apple features such as the sleep mode? I don't mean to sound like a demanding jerk of a customer but I dont think it is too much to ask that my computers advertised features (PCI expandability and sleep mode) both be able to work together.

    Hi
    xlr8yourmac.com has a wealth of info on compatable devices of all kinds, it's often worth looking there & other Mac sites before purchasing..
    Apple cannot possibly determine compatability of all available 3rd party devices, it is up to the vendor to determine what systems/OS versions their hardware will support.
    I would stick with a vendor that is known for Mac support, such as Sonnet (or others that are sold through Mac sites such as OWC, SmallDog,etc.,) unless you are willing to do significant research on a specific product for compatability with your specific setup prior to purchasing.

  • Lost USB 2.0 card function and new startup disk issue

    I have recently developed a problem with lost USB 2.0 expansion card function after my MacPro awakens from sleep. My Apple USB ports are maintained without interruption. No recent software/hardware additions but maybe a recent OS security download or Apple software update.
    My USB card function returns after a reboot only to be lost again by any sleep. On reboot I now notice a ? folder prior to my Grey apple logo and normal startup. This finding occurred at the same time as the USB card issue.
    I am running 10.6.8 on a dual core intel Xeon. I had previously lost this same USB 2.0 card function with sleep after a 10.5.1 install.  I think it was fixed in 10.5.2 upgrade. Tried resetting PRAM but no change. Could this be a motherboard battery failure?
    Any suggestions for me?
    John B.

    I am experiencing the same issue. And I also had the same problem back at 10.5.1 as you did. I will turn off the sleep function for now, but this is ridiculous!
    My system only has the internal (Apple supplied) OEM USB card/ports. Nothing installed by myself. So this is insane to think that this problem keeps popping up. Ever since I updated to 10.6.8, all of my USB connections go down after sleep. But that's not all, I cannot even connect many of our external drives to the USB ports. When I connect them, they power up, but nothing ever appears on the desktop, nor can they be found with disk utility. They connect just fine with every other Mac in our office.
    This is all exactly the same as back with 10.5.1, when 10.5.2 came out the problem was solved.
    Apple, please fix this!!!

  • USB Card (w/o sleep issues) for PowerMac G5 1.8 MhZ DP?

    I know this topic has been covered before, but I'd like to get some up-to-date recommendations. I need a powered USB 2.0 card that doesn't have the dreaded sleep issues that many USB cards are plagued with. My computer is a PowerMac G5 1.8 Mhz DP.
    If you used any special drivers, please post a link to them as well.
    Thanks,
    Kelly

    If we understand why the usb powered devices cause issues, it helps to decide what, to hook up, where.
    When a command to sleep (or shutdown, for that matter) is given, the motherboard tells everything attached that sleep is coming, begin your protocals. Then, the motherboard starts powering down internals, one of the first being pci cards. If the devices attached are usb powered (no built in power supply), these devices can no longer communicate with the motherboard. Without these communications (ie replies) the motherboard sleeps what it can, and waits for the others to reply, though they can't. Thus, no deep sleep, sleep lock.
    Input devices, keyboards, mice, joysticks, should always be connected to system native ports. They draw power from the usb, as well as provide vital communication (ie wake up).
    Printers, scanners, scales(?), devices that sit around and wait for use, have their own power supplies, and are usually no problem. BUT, some do cause problems, probably due to proprietory firmware on built in ROM that runs in conflict with the system firmware, and sleep protocals. These devices must be tried, one at a time, to test the overall compatibility when attached thru a pci card.
    Hard drives and card readers are also case by case. Best bet is plug in to native ports, or try to "eject" or spin down prior to sleep. Motherboards communicate with all storage devices at sleep and waking, and a powered down pci will break necessary communications with these devices.
    I think ,as you have read from the experiences of others , it is necessary to have patience and try connections individually, then in combinations.
    If not completly necessary, opting for a powered usb 2.0 hub attached to a native port is the safest, and surest, bet.

  • USB 2.0 expansion card/ System sleep issues

    I have a Mac dual G4 1.25GHz system. I have 1.2 GB RAM and am running OS 10.3.9. I recently installed an Iogear USB 2.0 expansion card. If I have anything plugged into any of the USB ports on the card, the system will go into sleep, but not deep sleep (the fan continues to run). It will NOT come out of sleep mode. I have to press and hold the start button on the front of the machine to restart.
    If nothing is plugged into the expansion USB ports, the system operates normally. I would like to keep devices plugged into the USB 2.0 ports. Any solutions, answers? Thanks

    wow - this is bizarre...
    I have an iogear card in my G4 867 and no problems... Been running it for about 3 months, and leave peripherals plugged in... Though I turn off anything plugged in... Did you set Energy Saver to "never"...? I tried a Belkin card and had problems with it, but the iogear works like a charm... My computer specs are below - maybe something in there is different...?

  • USB 2.0 Card Issue After Waking - Solution?

    I know this issue has been discussed a number of places, and I have read a lot of the threads. I was curious though if anyone has found a solution to the issue of USB cards not working after waking from sleep. I have read that the thumb drive seems to do the trick, but for me I get no response, it still will not work. As you all know this is a problem, and renders my iPod useless b/c I can't dock it or charge it, etc.
    Point being - any solution yet? What about if the thumb drive idea doesn't work? Could it be b/c the thumb drive is not formatted specifically for the Mac (ie FAT32)?
    I just kind of wanted to get the solution(s) out there in one nice place.
    Thanks!

    Thanks, but deep sleep is not the problem. I've read a lot abotu that but have never experienced it. I am referring to the new prodblem induced by Leopard where the USB card doesn't have any power after wakign from sleep. There have been many discussions of it, and I just wondereed if anyone has a solution yet. The flash drive solution that works for some does nto work for me.

    If wjosten's tip doesn't work try plugging it into a USB charger (not through your computer), wait about 30 seconds and it should come on. If it doesn't remove the cord from the phone and keep trying this. I've had this same issue and found a combination of the reset & charging cable tends to work. Sometimes it takes about 5 minutes for the phone to respond.
    Best of luck.
