USB Mouse suddenly not recognized

[freakytiki4u]

Anyone ever repair a USB Mouse? It was working fine one day and then suddenly could not be recognized. I tried it on different computer and same thing. A diff mouse works on my computer in the same USB port just fine. Ideas?

Pics attached.

Usually it's a broken wire in the cable.

Re: USB Mouse suddenly not recognized

ok ty, I will meter test it immediately. Just to add, its a FELLOWES 98903. Ya know, just in case any wants to know. lol

Re: USB Mouse suddenly not recognized

All 4 wires test good with meter set to X1K Ohms, but the blue wire only tests about 50% of the way to max Ohms when the other 3 test 100%. That normal that you know of?

Re: USB Mouse suddenly not recognized

Max Ohms? Don't you mean zero ohms? A good conductor which is OK should test 0 ohms or close to it (My DMM for example says 0.02 ohms)

I take it you are measuring from the board end to the plug end?

Which USB pin corresponds the blue wire? There is not normally a blue wire in USB cabling (But I assume this mouse is el-cheapo and they have used whatever colour they could find)

Why are there no wires visible in your photos?

you didnt' feed it enough cheese and it died

Re: USB Mouse suddenly not recognized

not really worth fixing a simple optical mouse (unless it's some "high end" gamer crap which you could sell for a profit)

a no thrills optical logitech mouse is less than 8$ usually.

Re: USB Mouse suddenly not recognized

Why not fix it?

If the cord is broken, just shorten the cord past the break and reattach it.. that costs even less than $8 since it's free....

Re: USB Mouse suddenly not recognized

I completely agree with Agent24. I will post some pics of the wires soon. I'm not an electronics expert by any means so I must have meant zero Ohms, lol, sorry. I will post pics of test Ohm Test with meter in a few minutes.

Re: USB Mouse suddenly not recognized

Ok, I taped the cable to the desk and as you see it, I call the left pin #1 and I test them all with the corresponding color. OHMS is zero for all of them. Not sure why blue was 50% the other day, I may not have been holding the test lead good enough, very hard to work with small cable and hold tester leads all at same time, lol. I test each lead against all 4 wires and none tested bad. Only 1 reading per pin with 1 wire, so no short in any wire. I moved the cable around while testing to look for shorts. See attached pics, sorry for pic quality, was best I could do under the circumstances.

Re: USB Mouse suddenly not recognized

Agent24 yes I am measuring from the board end to the plug end without the cable attached inside the mouse. As you look at the pictures above, the pin on your very left side I call Pin #1 and then next Pin #2 until Pin#4.
They are as follows; Pin1 = White Wire, Pin2 = Blue Wire, Pin3 = Green Wire, Pin4 = Red

Thank You Smason, I decided to shorten the cable by 1 inch and now its perfect. Had to be a broken wire right where the cable comes out of the mouse. LOL

The simplest answer is usually the correct answer. Thank you everyone who responded.

Wooohoo! I was right. That's twice this week.

Re: USB Mouse suddenly not recognized

I did such a repair about two weeks ago to a Logitech optical mouse. I cut the cable a few inches and then painstakingly soldered the old pin headers to the exposed wire leads.

Unfortunately, I cannot get the same comfort and accuracy with it that I get with my old ball mouse while playing CounterStrike. I'm not sure whether it's the laser or the design of the mouse, but I just can't aim at the guys head fast enough. Unfortunately, no one makes ball mice anymore and I have had to resort to mixing and matching different pieces from different mice of this same model when something stops working.

Re: USB Mouse suddenly not recognized

connect your mouse via PS2 if you still have that port.
then set the PS2 scanrate up (there's a tool for that somewhere on the net).

that way, i can set it from painfully slow movement (halfway across the whole desk to get from one corner of the monitor to the other) to insane precision (moving the mouse 1-2cm and i went the whole 22" diagonal of my screen .. it's so quick that it's pretty much useless lol)

if you're using it on USB, pretty much all mice are kinda limited in terms of cursor speed and precision.. don't know why exactly..

PS: most optical mice use red LEDs. lasers are still relatively uncommon..

Re: USB Mouse suddenly not recognized

Yes, I had the thing in the PS2 port and the rate at 200, I always do that.

What I saw recently was Asrock released a motherboard with a USB port overclocked from 100Hz to 500Hz.

http://www.asrock.com/mb/overview.as...20Professional

Fatal1ty Mouse Port is a customizable technology for PC gamers that is a part of F-Stream. After plugging the USB mouse into the Fatal1ty Mouse Port and running F-Stream, gamers can use Fatal1ty’s personal preferred mouse polling rate at 500 Hz. F-Stream also provides the flexibility for gamers to adjust the mouse polling rate from 125 Hz to 1000 Hz. This is helpful for professional gamers to experience smoother game play and faster response time to the mouse.

Yes, you can also overclock your USB ports on ANY motherboard through a software hack, but you don't want to overclock ALL your USB ports, just the mouse port.

If I could find a nice ergonomic mouse shape with the weight in the proper section (The steel weights in the Logitech were throwing off my game because they were too high up in the mouse), I reckon this would work.

Another nice feature here is that this the the only Sandy Bridge motherboard I have seen with a floppy port.

Actually in this case what you are looking for is open circuits, not shorts.

Usually near the entry to the mouse the cable can break (as it's moving around a lot) - and in some positions the broken ends of the conductor inside the cable match together again and the thing works.

Probably your blue wire (which sounds like one of the data pairs) was in a position to have a bad connection last time but this time you moved it in a position where the internal conductors were touching OK.

Usually it's a broken wire in the cable.

Off subject but if you ever have an external power supply that the LED will light but will not perform under a load there is a good chance you have a broken wire at the power plug.

Of course, even if you cut the whole cord off the LED would still light, it's connected internally in the adaptor so not very easy for anything to go wrong with it...
