IMac G3 will not recognize USB upon startup?

The iMac G3 seems to be fine hardware wise, however, it will not accept any input upon startup and I cannot boot from a CD. I have tried booting whole holding down the C key, tried booting into options, open firmware, etc. All with no luck, it just continues to boot into a very blank OS 9.2 screen which I can do nothing with. Once it has "booted" I can move the mouse around, so the UBS ports do work, they're just not recognized when the machine turns on. I am using a standard Apple USB "Blue" Keyboard from 1999, so I can't imagine that being the problem.
I believe it is running a very old version of Macintosh Manager, as after a half hour it gives up trying to find a connection and asks me for a Admin Username and Password to quit into the finder, I have none. I am trying to boot using an original retail version of Mac OS X v10.0.3. This should theoretically be fine, as the firmware update was for v10.2 and newer, correct?
I have no idea, even if the CD drive is dead, shouldn't I at least be able to boot into terminal, open firmware, or startup manager?
Please help.

Jjust out of curiousity, what are you using for "boot from cd"?
I'd concur with your assesment of a bad cd drive. Perhaps you could try another drive from ebay.
Is this a try or slot iMac? Does the slot of firewire? I'd get a firewire cd drive if your machine supports it.
This site provides more information. Best for older machines. Note, serial number is sent in the clear.
"A serial number is a unique, identifying number or group of numbers and letters assigned to an individual piece of hardware or software. It's used for various things depending on the product / brand but what is your Mac's serial number for and more importantly... what is it hiding and what can it do for you ?"

IMac 400dv will not recognize new hard drive installed

Hi,
I had been having trouble with my iMac 400dv's hard drive. I had posted the problems I was having and had gotten some very nice feedback. The final decision was to install a new hard drive and battery.
I purchased a refurbished 40GB Maxtor to replace my old 20GB. Installation was no problem except that my iMac will not recognize the new drive. If I reinstall the old one, it recognizes it right away, so I know it has been installed correctly.
I took the new hard drive back to the store and the tech said that it wasn't set on the "Master" position. He set it and tested the drive and said that it was fine. I reinstalled and get the same result, no drive can be sellected to install the software. No matter where I set the pin, I get the same result. I called the phone help line (MicroCenter) and the new tech told me that the drive was too big for my mac, which makes no sense to me since they suggested I buy a 100GB in the 1st place.
I have 1GB of memory, my installation disk if for 8.6 and I will bring it up to 9.2 if I can get it running again.
Any suggestions?
thanks,
Lucy

Lucy Rust...
In my opinion no Macintosh user should attempt to install a refurbished HD under any condition. Especially any HD that is to be bootable as they are no longer reliable for the Mac.
Master setting is a must for the HD and never tinker with an optical setting. Well, if you could mess with the optical setting, expect to do some micro-surgery.
You should be good for a HD up to a capacity of 120GB. The threshold is somewhere around 137GB but you will not find such odd capacity on the market.
I think the rest has been covered.

Itunes on my Imac G5 will not recognize any of my ipods

I was given an Imac G5, which has hardly been used and had never ever had any updates. I connected my Ipod Classic and Nano ( all circa 2007, 2009) and Itunes doesn't recognize it as an Ipod so I cannot sync them. I am very new to the Mac World and would like to know if I can update the operating system ( Panther Mac OS X) to another more current system. I downloaded Itunes 10.1 but all I keep getting is a window saying "The Installer Package " Install Itunes" cannot be found. The Bill of Materials for this package was not found". I am sorry I have no ides what this means. I hope someone can help. Many Thanks
Simone Cutlack

Panther is quite outdated operating system, it would be better if you could upgrade atleast to 10.4 "Tiger", 10.5 "Leopard" is the last operating system which will work with PowerPC -processors (G3, G4 and G5) so you might want to upgrade as much as you can at once. Apple does not seem to host any versions of iTunes on their website which would work on 10.3 "Panther". iTunes 10.1 will not work with Panther. I Googled quickly and it seems that iTunes 7 is the last series which workd on 10.3 but they might too old to support your new iPods.
I think you'll need to upgrade your OS.

My imac G5 will not recognize my new iphone 4s

The G5 has the 10.5.8 , not sure if this is the problem?
What I really want to do is export my address book from the imac to the iphone. I saved them on the imac as vcards from my android phone.

Yes, your iMac can run Mountain Lion per this article: http://support.apple.com/kb/HT5444
(I assume your iMac is five years old or less.)
You are running Leopard, which is at least three years old, and probably older.
You will need to purchase at least Lion (last year's OS X), and at least iTunes 10.7 (current is 11.0.1).

Windows 7 repair will not recognize USB disk

I have a system image I created in Windows 7 that I want to restore to a partition on my iMac hard disk. It lives on an external USB drive.
However, when I boot Win7 in recovery mode from the DVD, it is unable to see the external USB disk. I assume this is because it needs the Windows boot camp drivers.
How can I make these available to the Windows recovery mode?

I did, thanks.

Satellite L300D will not recognize USB Disc unless WLAN is disabled

I have a venerable Satellite L300D running Vista SP2. I also have a Fujitsu 40Gb SATA disk drive from my old laptop in a USB 2.0 caddy, with dual USB plugs to draw more current.
I can connect the USB caddy successfully to my Windows 7 laptop through a single USB plug on a USB 2.0 socket so I know it works.
On the Satellite L300D it sets up the Generic USB disc in device manager, but does not register the 2 disk partitions as filestore in Windows Explorer. In fact when you try and expand COMPUTER in explorer it times out.
I noticed that the WLAN (Realtek TL8187B) is on the same USB 2.0 Controller, so I disabled it. This switched off my Wireless, but immediately Windows Explorer fired into life and I could access the partitions (D: and G:) and could even run check disk (no fails) and defragment it. As soon as I ENABLE the WLAN driver the disc fails to register.
I have updated the Realtek drivers from the Toshiba web site, but I would like a solution that allows me to use the disc AND the WLAN at the same time.
Anyone any ideas?

Thanks for getting back to me.
I use both USB drives and a Toshiba external HDD and SyncToy to backup my files - both without trouble. The Toshiba HDDworks fine today - in Device Manager it is recognised as "TOSHIBA External USB 3.0 USB Device" (even though I dont have USB 3.0 ports on my laptop) and is recognised by Partition manager as disc D:. The Disc caddy is recognised as "Generic USB Disk USB Device" - but not by Partition Manager - both use the same driver and hang off the same controller. The Caddy disc works fine on my other laptop (Windows 7) and once I've disabled the WLAN.
I had not done any specific driver downloads other than let Windows Update do its thing. It has taken me to Vista SP2 and I note that the "Standard Enhanced PCI to USB Host Controller" (above the USB Root Hub and USB Mass Storage Device in the Device Mgr hierarchy) are at File Version: 6.0.6002.18465(vistasp2_gdr.110505-037).
Since I noticed the recognition problems and interaction with WLAN, I have done some attempted repairs (1) downloaded the latest Toshiba realtek WLAN drivers "6.1162.0610 built by : Win DDK" (realtek_wlan_20100225.zip) - but it was failing before then. (2) I have also upgraded the BIOS to version 1.80. (3) The only other change I've made is to change the driver on the PCI bus from AMD (3GIO) Filter Driver to PCI Bus on advice from another forum.
When you say "remove the WLAN driver, reinstall the chipset driver and install the WLAN driver again" what exactly do you mean? EG in deveice manager - select WLAN - do uninstall ; what do you mean by chipset? - uninstall the Controller as well or some other device?

I have new 2T iomega external HD (Mac Companion) - my Mac (2.8 GHz i7 - Lion OS) will not recognize HD if hooked up with Firewire, but it does recognize if hooked up via USB - how can I get it to recognize with Firewire?

Try a different FW800 cable and also try doing a SMC reset. If neither work try another FW800 device to see if it's recognized, if it is then you know it's not the Mac it's probably the EHD.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

My USB ports will not recognize any devices, iPhone or external drives. Keyboard and printer work, any suggestions?

My USB ports will not recognize any devices, iPhone or external drives. Keyboard and printer work, any suggestions?

I'd start by looking in system profiler.
the blue Apple icon > About this Mac > More info...
goto the hardware section. Scroll down and click on USB
See what happens when you have the device plugged in & not plugged in.
Move keyboard & mouse around to verify that ports work. Plug device in a port that worked with keyboar or mouse. Keyboard usb ports are rather low power.
Perhaps device is taking too much power. Are devices power or unpowered? Try connecting devices to a usb hub.

Hello:
This is not an area I have much experience in......I rarely insert DVDs and I have never had a similar problem.
When the DVD is in the drive (and DVD players is open) click on File>get disk info.

I am reading on this site about the error I am getting and it wants me to change some files that I am not comfortable messing with. Mainly because it is like a foreign language. Will the store do this for me or tell me if it is neccessary?

Just started up my Mac Mini out of the box, using a USB windows keyboard, it will not recognize letters so I am unable to enter serial number. Anything I can do to get the mini mac right out of the box to recognize the windows keyboard? Do I have to buy an Apple Keyboard to get it to work right out of the box?

Is this a normal USB keyboard or is there anything specialized about it? Does this keyboard require you to install any special software to use it on a Windows box? Or is it usually a plug & play keyboard?
Normally if a Mac does not recognize a keyboard it asks you to press certain keys to identify the keyboard. What is happening on screen with this keyboard? What serial number are you referring to?
