My iMac OS 10.7.5 will not connect iphone or flash drives via USB.

Hello,
My iMac (Late 2009) with an OS 10.7.5 will not recognize my iPhone 4S or any flash drives when connected to any USB port on the back of the iMac.
I have reset the PRAM many times and reset the SMC once.
I have repaired disk permissions.
I have run Disk Warroir repair.
Fixed other issues, but not the USB connectivity.
The USB ports will recognize my printer, a powered USB hub, and external HD. It does not show in my System Profiler as seen here. One bit of hope was when I first reset the PRAM and connected my iPhone to the back USB port my iPhone made several connecting sounds in a row, but failed to actually show up in iTunes or iPhoto or anywhere. My iPhone and flash drives do connect via USB on my Powerbook. So it seems to be some problem with my iMac USB drives.
Anything else to try?

My ipad will not connect to my computer throught the usb nor will it start

Do you mean that the iPad won't switch on ? If you do, then assuming that the battery isn't empty (and it can take up to 15 minutes of charging before it will respond), then have you tried a soft-reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
Or do you mean something else ?

Is it possible that iMac corrupts connected external hdd-s drive via USB?

Is it possible that iMac corrupts connected external hdd-s drive via USB? (two wd cav. green 2tb from different purchase went down in one day, both from the backside usb ports)
First one of my video storage hdd, full of files suddenly got extremely slow, and a few minutes later, it unmounted itself, but with the unmount error, but nobody even touched the cables, electricity etc. When I tried to mount it again, it did not respond, just give a periodical load light and ticking. First I thought it must be hardware failure, but since I bought a brand new drive today and it made the same problem as soon as I tried to format it. I got suspicious. The consol, said about these - i googled all but now solution so far. (WesternFresh is my drive)
Oct 23 17:10:58 xxxx fseventsd[47]: disk logger: failed to open output file /Volumes/WesternFresh/.fseventsd/636573acca1d6550 (No such file or directory). mount point /Volumes/WesternFresh/.fseventsd
Oct 24 10:55:42 xxxx com.apple.kextd[10]: Can't create kext cache under / - owner not root.
Oct 24 17:23:05 tmdc diskarbitrationd[16]: unable to probe /dev/disk1 (status code 0xFFFFFFFA).
and there was an I/O faliure not but it was on another mac - where i hoped itt will come back to live.
I think - if it is possible - that the OS maybe misunderstand something about these drives, and try to change - maybe permissions - all the time if a usb external connects...? (I am not really into it as you see )
Also about Disk Utility - it does not see any partition on the old hdd, but i shows the name of the product. If I connect the new hdd via the keyboard usb, the disk utility is able to see and format it, but the hdd will be still slow and tikking after it.
Also I tried Disk Warrior (freezd out) and Techtool Pro 6 thanks to some ol'frineds - which also not saw the old hdd, but did nothing useful with the new one.
About cav green: I have 3 of them and no error so far, and got 4 1tb cav green in 2 mybook studio II also without any problem.
Iam a bit scared, and try not to plug in any usb hdd-s now, but I have to continue work, so I need solutions.
I hope if it is not hardware failure, maybe some tricky terminal code will bring back the viability of my old hdd - and I won't have to spend a lot of money to recover data.
strange.
if anybody has a clue?
update 1:
i found this post also:
https://discussions.apple.com/message/15905481#15905481
I also made the mentioned steps - but it is a bit different sice it reproduce itself and I cant use DU.

It turned out that WD is the big bad guy in this game.
According the data rescue company where I asked for an inspection, both of the drives had their reader head loose. And in the one, which was my already-in-use disk its even damaged the platters... xxxxx
So its time to pay bunch of money to recover, and take a walk to wd service to bang on the desk.
Also note - it may be somehow related to intellispeed technology - since macs not really friendly with wd-s built-in solutions.
On the other hand, with WD GP 1Tb there is no problems at all for ages.
thanks guys, thread is closed

My airport network will not connect to to the internet via my modem. My host computer is a hp running windows xp. I have had great connection for 3 years. Then suddenly can not connect. Please can you assist

My airport will not connect to the internet via my modem. Worked for 3 years. Suddenly stopped. Main host computer is hp running windows xp.
When trying to connect windows states connection was cancelled. I have had hp checked by compputer repair and still have same problem?

The router is much, much newer than the computer, perhaps some characteristic of the WiFi network as it's currently setup is preventing the computer from connecting.
Try to go back to the basics: set your WiFi network to "b" mode only (i.e., turn off "g") and termporarily remove the password from it. See if the computer will at least establish a connection at that point. Then start turning on one thing at a time ("g" mode, then security, etc).
Not sure what format your WEP key is, but if it's not 10 characters (the minimum for the standard, which constitutes a 64-bit key), you can try making it that long. If it's 13 or 26 characters, it might be a higher encryption than the computer can support.
If all else fails, you could try looking on ebay/craigslist for a copy of Tiger to install on the iMac, which would have software support for more WiFi encryption schemes. Also, it would provide software support for USB WiFi adapters that would also be able to connect to more modern networks.

Imac suddenly shut down and will not connect to internet

Hi, my imac running snow leapord was working fine. Then when I came to it a couple hours after using it it was shut down. When I restarted it would not connect safari or google chrome to internet. However, some websites it could access. All the login websites can still be used. My internet connection is good, I have another computer running on same modem and it works fine and internet provider has checked out the connection and it is good.
Error message - server has unexpectadly dropped the connection.

My MacbookPro will not recognize when a flash drive is put into the USB port. It does not show in finder at all.

I put a HP flash drive into a USB port and it never shows in finder under devices. I want to copy photos to it to load onto a electronic picture frame. Why doesn't the flash drive show in finder?

First, open up the Apple System Profiler by choosing Apple Menu > About This Mac, and then click More Info.
then select USB off the hardware list. If your flash drive is connected to the system, it will appear here. If it does not appear, there is a problem with either the port or the drive.
If the flash drive shows up in the system profiler, the problem is in your Finder preferences. Finder prefs (⌘+comma) allow you to designate what shows up on the desktop and Finder sidebar.

Officejet 4630 will not connect to computer through wireless or usb since installing Windows 10

I have tried to install updated software for said printer but it still refuses to connect to my pc through either of the two mediums provided. Bit unstuck due to this as it is my work computer. Admittedly should have waited a while to install windows 10 but I got a bit caught up in the moment and didn't consider that issues such as this may arise. I also have a HP designjet T120 connected to this PC and that still works wirelessly no problem at all!

Palm Centro (OS 5.4.9) not connecting to ActiveSync 4.5 via USB

A friend of mine has a Palm Centro (OS 5.4.9) from Verizon. She uses this device to sync to Lotus Notes 8.0. This requires her to have the following software applications installed on her Windows XP pro-desktop computer.
1) Microsoft ActiveSync 4.5
2) Palm Desktop/Hotsync 6.5
3) Mnotes 4.1.4
When she plugs her Centro into an USB port--Hotsync has no problems detecting the device. However, ActiveSync cannot detect the device. Some of the things I tried to fix the problem.
1) Soft & hard reset on the Centro
2) Remove & reinstall ActiveSync 4.5
3) Try every USB port on the computer
If you have any suggestions it would be greatly appreciated. Otherwise I told my friend to turn in her Centro and move to a Blackberry. They are far easier to sync with Lotus Notes 8.0 email.
Thank-you !
Post relates to: Centro (Verizon)

I also have a Centro from Verizon and am synching with Lotus Notes. I am using the Palm Desktop (latest release 6.2 from Palm website) and Lotus EasySync v4.2.6 ( http://www-01.ibm.com/software/lotus/products/easysyncpro/ ). In additon to synching with Lotus Notes I am also synching with my personal emal from comcast. I am able to synch with my calendar and contacts with no problem. However, I am not able to synch with my mail account because I am using the Versa Mail application to get my personal email form Comcast and there is a known conflict between VersaMail and EasySync (Versa is controling the mail conduit so EasySync can not synch mail). If your friend does not need to access a personal mail account like I do they should be able to get full synch with EasySync, if they are using VersaMail they should be able to get calendar and contact with no problem. Another optin would be to subscribe to Verizon's premium data service ($49.99 for me) and access personal email through Verizon Wireless Synch and then use EasySync Pro to synch wiht Notes. i hav e not tried this optio, but based on my conversations with support from Verizon, Palm and IBM this souds like it should work, personally I am not willing to pay the price for the premium service.
If you need additonal information on my setup replay to this thread and I will be happy to give more details
Hope this helps

Both my iMac and macbook pro will not connect to a certain web site?

Both my macs (21" new iMac & a 2008 macbook pro) will not connect to foxcycling.co.uk. I know the site is live as I can access on my iphone and ipad.
From what I've read on the forums its a settings issue which probably migrated from the macbook to the iMac when I migrated the data.
Very frustrating ....
Any idea's and simple solutions?
Both systems up to date etc

OK, OS X does not include Adobe Flash. The website is probably Flash based. Chrome has Flash incorporated into it. If you want to download and install Flash visit Adobe's website and download Flash for your system.

G4 iMac will not connect to internet

Hey all.
Got in a G4 iMac 17'' 1GHz. It will not connect to the internet thru ethernet. It works fine through AirPort though. I've tried everything I can think of. Reinstall the OS, create a fresh user account. Nothing works. I'm guessing there is something wrong with the ethernet connector on the logic board. The computer was dirty and had a lot of water marks on it like it had been sitting next to an aquarium so my guess is water might have gotten in the bottom.
Think I'm right? Or is there something else I can try?
Thanks in advance.
Thomas

I've never had to use it, but the OS X CD/DVD that came with the system provides a set of diag tools. You boot from the disc, and run these tools to check hardware on the machine.
I am sorry I don't have any further clue on that specific tool set or how to use as I never have. I simply know it exists.
Quite sure a bit of searching on the forums here will reveal the boot-disc options, etc. Heck... you may find info on the disc itself, try inserting it, opening and see what is what.

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet".How can I change ip address?

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet". If this is the root of the problem,how can I change ip address?
Ipad will connect no problem to other networks.

First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.

New iMac 27" WILL NOT connect the built in webcam to any websites. HELP!

Hey,
I have the iMac 27'' 2.93 GHz Intel Core i7 16GB.
The built in webcam, (and also any USB webcams I have tried to connect,) will not connect to any websites such as Chat Roulette, or any other broadcast website that requires Adobe Flash Player. I hit accept, and it just comes up as either a black screen, or says detecting video. (Depending on the site.) I have tried on multiple browsers, is there a random setting I don't know about?
The webcam works perfectly with Skype, Photobooth, iChat- but it will not work when trying to broadcast through any website.
Can someone please help me solve this problem!? It's ridiculous.
Thank you! I will paypal anyone who comes up with a working solution for me $10.00!

BUMP!

My imac and ipad2 will not connect to the internet with Windstream using an 2wire DSL modem.

Help my brand new imac and ipad2 will not connect to the internet with Windstream using an "2WIRE" DSL modem. Windstream tech service is useless. i can connect with the built in router through Ethernet or wireless, but still no connecting to internet, help! windstream said everything is working on their end, yea right. What i do know is that both the mac and ipad work at other places and can connect with wireless connected to the internet, so i know it's not the apple products.
these are brand new machines with lion.
This is my first mac, so I’m still new to how it works, which is not helping either so a detailed help would be great. Please help before my wife losses it
thanks

There is a 2701HG-B, and a 2701HG-D. If not labelled on the modem, ask Windstream which one they presently supply or how to tell the difference.
By the way tell your wife it isn't that bad. At least you have an ethernet DSL modem. There were times where DSL modems had RJ-11, USB, and Ethernet, and all three were used to provide access. At least now only the craziest DSL providers still use those modems.
