1. It depends on whether the devices have their own power supply or get power through the USB bus, as well as how much power they require.

Looking for USB hub

Hi
I've been looking around for a decent USB 2.0 hub, one that gives at least 3-4 additional ports, but all I find are fancy looking ones that cost upwards of $30. Is that the standard for USB hubs, or are there some cheaper ones someone could point me to?
Thanks.

Richard Habiniak,
US$30 for a quality self-powered USB 2.0 4-port hub sounds about right to me. Keep in mind that you don't necessarily want the cheapest hub you can find. Bus-powered and/or cheaply made / poorly shielded hubs can cause USB signal reflection problems, typically spurious wake-from-sleep signals but also general USB signal degradation and noise.
Also, watch out for really cheap USB data cables --- cheap thin cables are prone to the wires breaking and are poorly shielded to where you can almost expect serious line noise crosscoupling into the cables, which can lead to the computer locking up. (Happened to me with a cheap media card reader --- the thin cheap USB cable included turned out to be why a Mac running OS 9.2.2 would lock up randomly. The fix was a better quality USB data cable that as I remember it cost about as much as the card reader did.)

Need Laptop Audio Amplifier for USB Connected Speakers

For a laptop, does Creative have any kind of audio amplifier for USB connected speakers?
I think the laptop has what is called an Express 54 slot.
I am looking for amplification suitable for speakers, not headphones.

If their only connection to the laptop is via USB than you can't amp them without doing some internal modifications. It means the speakers have their own audio device internally which is receiving signal via the USB port, processing it and then outputting it via likely a weak amp stage to the speakers - you'd have to physically intercept that last part of the chain to add an amplifier.
Not saying it can't be done but you're looking at either harvesting an existing amp (which Creative don't seem to sell) or creating one from scratch (like the Penguin Mint amp, Objective 2, etc) for the purpose.

Looking for USB Hub compatible with Mac Pro 8 Core (early 2008)!

I need a good, reliable USB Hub. I was looking at a D-Link with 7 ports but I read a review on Amazon saying it didn't work well with 8 core Mac Pro. The reviewer said the Mac only recognized some of the time upon start up and he had to unplug and replug to get it going.
Not sure if this was user error or faulty product.
Anyone have any experience with a good reliable 7 port USB Hub? Perhaps even with this D-Link?
Thanks!

There are also reports (see http://www.hardmac.com today) of over loading USB ports on Mac Pro... even if you only use the available ports and hubs (like Cinema Display which should be getting its own power, but does not).
I would strongly recommend a PCIe controller first.

I need to find a powered usb hub that works with my Macbook pro

I've got a macbook pro mid 2010. And 2 usb ports isn't enough. Even with the powered hubs taht I have tried none will seem to charge my ipad 2. It only works if it is plugged directly in to the Macbook. So is there a powered usb hub out there that can handle having an ipod and and ipad plugged into them and actually charge these devices. Thanks in advance.

Yes. Google...

Need to find replacement for USB cord

Hello!
(I'm sorry if I posted this in the wrong area, but it seems the Toshiba website is a bit of a hassle to navigate through so I gave up, and hoped that the forums could offer me assistance.)
Ok, so a couple of years ago I recieved a Toshiba External Hard Drive (model: HDDR160E03X). It worked great, stored all the files that needed stored etc. But the cord that came with it broke, and was repaired a couple of times. Now the cord is to the point where it cannot be repaired anymore (without a serious amount of work at least).
So I am looking for a USB cord that will work for it. I've tried multiple cords already, but they don't power the external hard drive (it is USB powered) so it doesn't work properly. I haven't been able to find a replacement, which brings me here! Does anybody know where I could find one?
Any help is appreciated.
Solved!

You don't say so, but I infer it's one of those cables that draws power from two USB ports (aka "Y Cable"). If so, here's one.

I need a power adaptor for my 1st gen Apple Cinema Display

I just moved, and I lost the power cable to my first generation Apple Cinema Display (20" I think). It looked like the old powerbook cable, kind of a blue wheel thing-a-ma-bob. Any ideas? It seems as if Apple only sells the accessories for products they are now selling this week.

This is the usual solution for an ADC display that does not have an AC power cord to be used with a Mac that has only a DVI output. This device adds up to 4 Amps of power at about 25 Volts to power the display:

There are also some cruder versions that use the external Power supply brick "borrowed" from a G4 Cube.

Suggestions for USB hub

I'm finding myself having to swap out USB cables so I can use my printer, camera, external HD, yada yada far too often. I want at least a four port hub that is slim enough that it can be attached to the backside of the iMac without looking too horrible. Has anyone done this that can suggest a good model that is a close match to the iMac?

Hi
A Powered hub is best and I'd recommend a Belkin 7 port powered
hub. Very good never given me any trouble at all. Used with Printer,
digi camera, USB hd etc... Works a treat.
Er fits well under my G5 handle but iMac well it may be visable....

Need help on USB hub for mac air 13 inch (2 external hardisk and Iphone)

Hello everyone, I am a new macbook air user, and currently using 2 external hardisk of 1TB and 2TB. I am looking for usb hub that support both of my external hardisk, ethernet and iphone too. The problem is, limited usb hub for mac air and bad review on balkin product, any advice for me?
One more thing, I just moved from window to mac for the first time, and bought Western Digital 2TB external hardisk, the problem is, I can't save any video/audio file that I downloaded from internet in macbook to be transfer/move to this WD 2TB external hardisk, except for back up and time machine. It refuse to except any file that I try to move in to the external hardisk Can anyone help me? compactibility problem?

First, I have not found any of my hubs to have an issue with my MBA. Just make sure that if any peripherals you attached to the hub are adequately powered. Either by having the hub independently powered, or the devices having their own power supply.
The drive problem you have may be due to the file formatting. If this drive is formatted NTFS, then in many cases you can write to it using a network protocol, but OS X can't write to it if attached directly to the computer, e.g. USB, SATA, FireWire. You will neeed to either format the drive as a HFS+ drive, or use software that enables OS X to write directly to t a NTFS formatted drive, such as NTFS-3G. DISCLAIMER: As the information you provide for your circumstances is limited, this is but one suggestion amongst many, that explain your situation.

Can I use Airport Express to connect to a printer, Time Machine Back up drive, second b/u drive, and scanner through a USB hub? if so, how?

I have an Airport Express that connects to my printer. I'd like to add a scanner, and two back up drives (one for use with Time Capsule, another specifically for photographs backed up from Adobe Lightroom.
The printer connects to the Airport Express through a USB hub and is recognized. I cannot get the scanner nor either of the back up drives to be recognized. Is there a way to do it or will I need to rely on a USB hub wired to the USB port of the MacBookPro? If it is possible, can you walk me through the set up for each?
Thanks,
Doug Earle

I'd like to add a scanner, and two back up drives (one for use with Time Capsule, another specifically for photographs backed up from Adobe Lightroom.
Unfortunately, the USB port on the AirPort Express will only work with a compatible printer.
It will not work with a scanner, copier, or hard drive.
It should be possible to do what you want by connecting a powered USB hub to your Mac and then connecting the devices to the powered hub.
The setup for the scanner and hard drive would be covered by the manfacturers documentation, so providing specific advice for those types of products would be outside the realm of this support area.
But, if you can provide model numbers, it is always possible that another user who is using those products might see this post.

Could I use a USB hub to connection both a printer and an external hard drive to the time capsule?

I am planning on purchasing a new router. The Time Capsule looks amazing. However, I have Macs and PC's in my how. So, I need to know if I can connect a printer (for all computers) and external hard drive (for the PC's) by way of a USB hub on the Time Capsule. I've read that you can do this with the Air-Extreme.

Couple of comments:
You will need to use a powered USB hub to connect multiple devices to the USB port on the Time Capsule
The hard drive for use with the PCs will not be compatible for use with the Time Capsule if it is currently formatted for Windows NTFS, which it likely may be if you have been using with the PCs.
Same info applies to the AirPort Extreme.
The following hard drive formats would be supported:
Mac OS Extended (Journaled)
MS DOS FAT32

Good USB hub to use?

I was needing some input on which USB hubs are good for the MBP? Also, do they make a USB hub that plugs into the firewire port on the MBP?
Thanks

I use D-Link DUB-H7. It has 7 expansion slots, and the option to use an external power supply, though that 's not always necessary. I would use the external supply if the connected devices draw too much power.

USB Hub: What Kind?

I called the local Apple Store here in Walnut Creek, CA this morning and they had one in stock...standard configuration...so off I went and purchased it...obviously some stores have inventory.
I will need when I travel a USB Hub since I like working with a mouse and see myself at times using the USB ethernet adapter as well.
Do I need a powered USB Hub? I've read that the USB port on the MBAir is a bit different in that it supplies some additional power than a standard USB port.
What kind do I need?

The Squid looks interesting...but I see it is not a powered hub...I am wondering if that will work for the MB Air?
Mac Book Air has a single USB 2.0 powered port, whether it supplies enough power for all the devices you want to run off the hub may be another matter .

I need a wireless usb adaptor for a Power Mac G4... any suggestions? (needs to be compatible)

I need a wireless usb adaptor for a Power Mac G4... any suggestions? (needs to be compatible)

With Mac OS X 10.3 or higher, a number of USB Wi-Fi adapters would be possible to use. However, for an earlier operating system, a wireless Ethernet bridge (such as the examples below) can be a better (and sometimes the only) option. A wireless Ethernet bridge does not normally require special drivers, and can thus be used with almost any Ethernet-equipped computer.

I have recently upgraded my iBookG4 from Tiger to Leopard 10.5.8 and find my Bluetooth USB adaptor no longer connects. The Bluetooth pane says inactive. Does Leopard require USB 2.0. I've had the adaptor for some time so may be USB 1.0

I have recently upgraded my iBookG4 from Tiger to Leopard 10.5.8 and find my Bluetooth USB adaptor no longer connects. The Bluetooth pane says inactive. Does Leopard require USB 2.0. I've had the adaptor for some time so may be USB 1.0

Bluetooth icon on menu bar shows bluetooth off. When opening bluetooth preferences it shows the devices I've connected previously,( my mobile phone), and other devices I've attempted to connect but not very successfully: my iPhone and MiniMac. The bluetooth dongle in the USB port shows a continual blue light but does not react and the iBook does not recognise that it is there. There is absolutely no reaction when I try to pair my mobile phone, which I've done successfully before upgrading to Leopard, either by the iBook or the mobile phone.
I assumed that Tiger was not bluetooth compatible with the iPhone or MacMini running SnowLeopard and hoped by upgrading to Leopard I could achieve some file transfers between the three devices (iBook, iPhone and MacMini)
