    Default Simple Computer Question

    Hey guys, here's a question for you guys.

    Recently I notice that my mouse (razer diamondback) keeps connecting and disconnecting when I'm using the computer. It's especially destructive when I'm doing PP work or playing CS, for example.

    Now, here's my situation. All my computer USB ports are filled and I just bought the powered-by-usb flatbed canoscan at comex (with a printer, of course) and I just have this feeling that my PSU is a bit too little for what I have. It's a 450 or 480W one, and the usb ports are used for: Mouse, Printer, Scanner, Camera-USB cable (looking to replace it with sandisk CF reader).

    So, my question is, what can I do to stop this disconnect/connect problem? Razer mice light up when it's powered, and when my problem happens, I see the light in my house flickr, making me believe that there is a lack of power.

    Would those externally powered USB slots work in my case?

    Thanks

    Maybe you can try the remedies below:
    1. replace the battery in the mouse if its wireless.
    2. reset the wireless signal as it can sometimes go bad.
    3. for usb ports, group the less essential usb peripherals into one multi usb adapter (ie four items) and plug in that group if you need one of the to work.
    4. get a good brand adapter (eg berkin), one that comes with a power adapter. It helps send current to facilitate better transfer rates and connections.
    5. or change the mouse and disable some un-important usb items.

    My mouse is wired, so #1 & #2 are out. All my USB connected gadgets are important and used everyday, so that point is moot. I will try #4 first, and if all fails, I'll change my mouse.

    Thanks for the quick reply!

    Which port is your mouse plugged into?

    If it's not a powered port, then there could be some problems with the data/power transfer.
    Alternatively, there could be something wrong with your USB port. Consider switching to another port directly connected to the motherboard to try.

    And getting a powered USB hub to supply alternative powered ports is another idea.

    The mouse has always been connected to the motherboard ports (there's only 4 at the back, and that's all used up now) and has never actually given my a problem until a month or 2 ago.

    I think I'll get a powered USB hub. How much do the reliable ones cost?

    I guess the others here had more or less cover the basics of what might have caused the problem. So I am going to target some things which might need your attention too.

    1) You say your house light flicker when the mouse problem happens. So I am wonder if you are about to suffer a brown-out at home. Some time a power snap or burn out happens really fast...one BANG and your home power get shut down or it trips your power breaker. But at times it is slow to reach that point. Check your main power line from your PC to your power socket to see if you can see sign of like burn or smoke mark on the 3 point plug side. You do that by pulling out the power plug and looking at it. Next is you smell it for something burning. I had that happen to my power socket years ago when I over loading to many plugs into one main socket that heated up 3 pin plug that everything was drawing power from it and it heat up and was slowly but surely burning with some sparks to the point it was melting the brass pin head and the wired inside the 3 point plug. Worth take it a part to check.

    That kind of spark can cause flickering effect in your room lighting too if your light and other stuff is drawing from the same electrical line or source. That too is a very dangerous thing for your data as a flickering electrical source will cause your HDD to be unstable over time.

    If your electrical plug(s) to your PC and other peripherals are not the problem, check other power devices in your room or house even. Flickering usually mean something in the home is underpower or have a faulty wiring..etc.

    2) In XP...go to the control panel and go to hardware and look atyour device manager and go to the USB controller directory which if you collaspe it, all the USB devices on your PC will be listed (mine has 8 your might be the same or 6 eg) You can right click each one and set the power management to let window XP power it down when it is not use. Device that needs to always be left on you just keep it in default (with the check mark disabled) In the same directory you will also see USB host controller or something close to that...here you go into properties and it can tell you many volt is used by that USB point.

    I am not sure how old if your PC....if it is a P4 or Core or Core duo and how many cards and things you have connected to your PC but 450 to 480Watt PSU is not alot AND...one brand's 480 can be very very difference from another 480 PSU. Some people make fun of those who pay as much as a $100 to $200 for a same wattage PSU like a 480 or 500 for example. There are other reasons why there are cheap ones and expensive ones. The Expensive one has additional control and ability to keep the electrical throughput or voltage constant at all time even if the load is pretty high but with poor brand or no brand PSU...what is stated can for one thing be not entirely accurate and you have to also know the rating for some of those power plugs that use to power your motheboard, Graphic cards, HDD...etc. Some of the watt and rating might not be sustain or up to the task to power certain type of devices. That is why most of us power users don't try to be too stingy with getting a good reliable PSU.

    3) If you want to know if your other USB devices are draining too much that it is effecting your mouse's functionality...just unplug all the USB devices you have no use for and then run your PC with it for a day and see if anything like what you describe will happen again. Another reason for unplugging it is not so much due to electrical but if the mouse's IRQ is shared or in conflict with another devices.. This is an OLD problem with older system but with newer ones I have not heard about it but worth trying. Usually in your motherboard defualt bios setting...the motherboard auto control the IRQ setting for all devices but at times certain device might run into conflict with it and thus sometime..a simple patch for your devices does the trick and consider updating your motherboard firmware or patch too. I have known it to help me once or twice before.

    all usb hubs are the essentially the same, except that most does not come with an adaptor... i just bought one for my lappy, a logitech usb hub for notebook premium type, which cost 49.90 SRP, challenger selling at 45 for members... dunno anywhere else cheaper. remember to get the premium one as it come with an adaptor...

    if you are adventurous enuff, you can just get any other brand ones, i got a nice looking one, then add a power adaptor i got from SLT with it, as long as the voltage, plug and polarity fits, it will work. remember to get a 5V one. think most Best denki have those multi adaptor type. can get it as well.

    with your problem, probably you have stressed your ports too much, now its giving way... you're lucky the board didn't give way. i never trust plugging too many things thru the mobo. imagine a surge is all it needs.

    Wa seh. I said simple computer problem.. haha, didn't know it'd be quite complex like this.

    I'm on a 3yo rig. AMD Dual Core 3800+ @ 2.0GHZ (stopped the overclocking already), 4x512mb ddr1, msi nforce4 mobo, 480W 'iCute' (eh?) PSU, Harddrives, audiocards and nvidia 7800gt stock speeds.


    S$45 seems about reasonable for a quality hub. I'll head up to challenger next time I go look-see at john3:16.

    Dang. Forget the hub. The computer just flashed the "Device not working properly" when my mouse keeps disconnecting. And it's doing that every 10secs after I start moving my mouse.

    So, what's a good mouse to get for image editing? Im using a razer diamondback first-gen one and I think it's good, but kind of not worth-the-price. I only got it because of the gaming mouse+pad combo that saved me S$40 last time.

    hehehe...see! Now you know why so complicated. Actually it is not complicated but if you want to save money and not make the wrong decision it is always good to do a few test. It seem "mah-fun" but once you do it a few times ...it is almost second nature to trouble shoot it yourself.

    Good mouse are not cheap if you want something really good, responsive..etc. Razor is one of the better ones around. Logitech makes good mouse...and like it or not Microsoft is pretty good too. For my graphic work I still am very old fashion I want a wired mouse with optic and I like it of a certain size and weight as it helps with my work in graphics...and wired means...it is foolproof against wireless related problems. Good mouse I see spending about $40 to $60 about right anything more I still feel abit gimmick and the extras are not really important to me. If I want to game I have specialised game mouse and external peripherals for setting up my macro key controls.

    in IT the practice is always to take every variable out and add them back one at a time, testing the same scenario.

    I agree with the above. In many scenarios, the malfunctioning device warning came out, so I guess my razer has to go soon. It blacked out just now, but when I changed to another usb port, it rose from the dead.. again. The warning still comes on though.

    Should i get back razer, or should I go with logitech mice? I quite like their old MX510 which I owned.

    I had the same problem. Had issues with my USB HUB.. hence I gave up on my Razer Krait. Happily using my Logitec MX Pro Revolution now.. and no such problems. (and yes, it's wireless now... haha)

    Have you tried refreshing your mouse driver? Anyway, if you had used it lots, maybe time to look for new one. I am using microsoft mouse on my mac, not much problem except batt replacement.

    yours could be a device conflict as what sammy mentioned, too. Have a new IRQ for it may help sometimes. But being windows, its supposed to be able to detect and fix it up. Its not win3.1; its vista now! And microsoft should have some smart tools already built in.

    I'd say the problem is exceeded USB power budget - some of the hub chip implementations seem to be a little dodgy - in theory you shouldn't be able to overload the USB power - each device is supposed to tell the hub what it wants and the hub should supply that and nothing more. The OS should be notified if the power budget is exceeded.

    In practice is appears many USB devices lie about their power requirements and draw more than they ask for, and some hub chips/drivers don't bother reporting power limits exceeded back to the OS - probably due to point one - devices lying...

    I suspect a cheap 'powered' hub will solve all this buy boosting the power available to run all these devices.

    Something else on the USB hub is probably drawing lots of power and intermittantly the lower power levels available to the mouse cause it to reset.

    The age of the PC indicated make me assume it's one of the older designs that only has 1 USB hub internally, so all those devices are being powered through one bridge chip.

    i used to have a diamondback... spotty reliability... the pointer would skip across the screen frequently... gave it away... simple optical mice are the best... actually... no...

    Alright, so the there are 2 possible solutions to my problem. One way is to get a powered USB hub, and another way is to try with a new mouse.

    I'll do both and more. Next week, I'll be heading to Funan to pick up Lightroom2 and a Sandisk CF reader (which will draw even more power next time). So, here are my questions.

    What would be a good USB hub? You guys tell me 'any cheap one' will do, but what's something that is reliable? Any specific brand/model?

    I'm looking to replace my mouse and keyboard.

    To anyone who games and also does photo-editing work, what's a good mouse that goes for under/around S$100? I'm not one who needs those extremely high sens 3200DPI stuff. I'm looking for a more rounded mouse, and I think the razer profile is too low for me.

    So I'm thinking it's between the tried-and-proven (I used MX510 last time) MX518 and the G5. The G5 looks better and the specs are better, whereas the MX518 is a bit cheaper. But which one is better? Oh, the G9 looks like crap, so that's out of the equation. I need on-the-fly sensitivity, which is why I tried Razer last time, but it broke down on my just after 2 years.

    And regarding keyboards, I'd need something with volume control and home/messenger buttons, or programmable macro functions. I need to switch to MSN messenger (messenger button) quickly or the desktop quickly (programmed Home button). Anyone know what keyboards offer these functions? The G15 looks lovely, but it's way out of my budget of.. you guessed it, not more than S$100.

    So effectively I don't want to spend more than S$200 on input devices..

    Any ideas?

    Oookay, I just got the Belkin 4-usb ports hub. I love that beige colored.. thingamagic for wires. Great for putting my mouse wire through so it doesn't get in the way.

    I'm hoping that this works out, power wise. Is there any difference (other than different power source) if I plug my stuff into the hub instead of the computer? Like slower transfer etc etc?

    theoratically, there should not be any speed difference...
