FireWire/USB hubs compatible with a Dual 2.0 GHZ G5

Hello,
I have a IOGEAR 7 port Firewire - usb hub connected to my dual 2.0ghz G5. Often when I start my G5 there won't be any working firewire and/or usb port. Sometimes they work, but overall is a pain./ Sometimes repairing permissions or reseting the nvram or all helps solve the problem.
Anyway, I would assume that the Hub is having some issues with the Firewire power coming from the G5
I am trying to find a list of Firewire/USB Hubs which Apple officially have said are compatible with the G5.
Do you guys know any of those?
Thank you

I still think save and consider the next revision to the iMac line rather than throw more at your G5.
SATA drives that you can use now and in the future are likely to be safe investments.
People have used 3 x 10K VelociRaptors, along with cheaper but still fast WD Caviar 640GB as a great way to improve performance. SSDs are fast but probably for 1st gen G5 would require a PCI-X controller.

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.

FireWire, USB hub

I'm looking for some advice on a self-powered hub to connect an Epson Stylus Photo 2200 printer, an Epson 3200 photo scanner, a Nikon CoolScan IV film scanner, and a LaCie 120GB external drive. The Epson devices have both ports, while the Nikon and LaCie are Firewire only. USB connection is not critical, but it would be nice to have. The hub, of course, will be connected to the PowerBook.
I've searched this forum, but have not found any postings about a firewire or firewire/USB hub.

Braby -
My experience with hubs has been limited to ethernet and USB hubs. Most have their own power supply, but I once had a USB hub that didn't, and I found it limited what devices would work with it. Since I've never used a Firewire hub before, I did not know whether there were powered or un-powered varieties, so I was just playing it safe.
I've found a number of Firewire hubs through Google and I have checked Amazon.com. Both sources have provided some information, which have been helpful, but not definitive. I was hoping to find an Apple user or two who have tried doing what I am wishing to do, and thereby benefit from their experience.
I'll probably try a Belkin, Buslink or Macally hub from someplace like CompUSA, so that if it doesn't work well I can at least take it back.
Thanks for you input.

IOGear GUH 420 Firewire/USB Hub

I purchased this IOGear GUH420 Firewire/USB hub to use on my new MacPro 2.66 Intel desktop. Ever since I installed it, my firewire devices have been acting up and I couldn't ever figure it out. I was having lockups, spinning beachballs, monkeys flying out the floppy drive slot (oh yea, no floppy drive). Suffice it to say my new macpro wasn't acting right.
I did some research today and found out that some Firewire hubs do not like the voltage that comes from the new G5's and macPro desktops.
When I did the system profile, all my Firewire showed was Firewire 800/400 or the like. No devices, no hubs!
When I disconnect the IOGear hub and reboot... viola! Firewire in system profile shows all connected devices and everything runs much faster and I have zero errors!
So far, I would have to conclude that the IOGear hub is not compatable with the macpro, or mine has just been defective all this time.
Anyone else have issues with this hub?
Thanks,

UPON FURTHER REVIEW
and extensive swaptronics....
The problem is not the HUB, it's the ADS Firewire 800 external drive case. It has 2 FW800 ports on the back and 1 FW400 port. I guess I assumed too much when I thought that I could chain a 400 device off the fW800 case.
When I connect ONLY the FW800 case to the MacPro, and do not connect any FW400 devices off the case, the firewire profile in system profiler shows everything as it should be.
I CAUSED THE PROBLEM AND NOT THE IOGear hub. I have posted my stupidity in case anyone was influenced by my previously incorrect assumption about the problem.

What is the latest OS I can use with a mac G5 with a dual 2.3 Ghz PowerPC G5 processor?

What is the latest OS I can use with a mac G5 with a dual 2.3 Ghz PowerPC G5 processor? Everything on my computer has been running so slowly in the last few weeks. Have I finally outgrown OS 10.4.11? Would there be some other problem that would sudden make all my speed take a nose dive? I have 8.5 gigs of RAM... Please advise!
Thanks! Matthew

Everything on my computer has been running so slowly in the last few weeks.
First open Console in Applications>Utilities, see if you have reapeating messages.
How much Free Space do you have on the Hard Drive?
At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

Is Easy Acc USB 3.0 hub compatible with Mac OSX 10.9.4?

I just purchased a new hub and my Logitech wireless mouse is not responding well. Is it the new hub? Can OSX 10.9.4 support USB 3.0?

USB 3.0 is an international standard. Yes, it's compatible with OS X 10.9.x
Reviews on Amazon from other iMac users have been positive.
Just like with USB 2 hubs, some devices aren't happy sharing.
I can't tell for sure it's the hub's fault. You need to try other combinations of connection.

What kind of USB hubs work with the 2014 version of Time Capsule?

The latest post I could find on USB hubs archived from 2012 and I'm wondering what today's information is.
I have a Sabrent HB-J3U7. It is a 7 port USB 3.0 hub, two charging ports and five "normal". I think I remember reading the charging ports can deliver about 2 amps each. Obviously the Sabrent is a powered hub. I plugged it into the TC's USB port and nothing. No lights on hub indicating a connection at the device plug in ports.
I did a little experimenting and the hub works fine when hooked to my iMac (OS X 10.9.4). The individual devices work fine when connected straight to the TC USB port. All I can discern is that this hub is not compatible with TCs. Too much power maybe? The iMac has a USB 2.0 controller like the TC and the hub works there so I don't really understand the failure on the TC.
Then, for some reason, I tried the hub when it was disconnected from power and I could finally see the Sabrent hub connected devices (32GB USB 3.0 thumb drive and 2TB USB WD Passport - both formatted Extended Journaled). So I plugged the Sabrent power up and it still worked. That is until I tried to rename the TC hard drive through Airport Utility which required an update to TC. TC wouldn't restart. Just a solid amber, not even flashing amber. I disconnected Sabrent and unplugged the TC and replugged and TC worked again but now I'm afraid of the Sabrent.
Does anyone have ideas about what is going on? Any help would be appreciated.

The hub is not compatible. It sounds like the unit is powering the link to the TC.. which would cause the TC to freeze up. You might need a special USB cable which has just data connection but no power.
It is really hard to get info on hubs that work.. particularly because there are so many around and many are changed .. eg if you buy a belkin this year it fails when last years one worked.. that is because all the manufacturer is farmed out to various factories in China who use .. the cheapest parts available today to build them.. next week it could be different.
The TC just doesn't have a huge amount of memory to store drivers for every USB under the sun. So some work some don't. The best I have found is the cheapest brand x USB2. I would not bother with USB3 since that chipset is even more unlikely to be supported than USB2 ones.
I have tried to get people to add to a database.. not much so far.

Is a DKE-2 USB cable compatible with HP Pavillion ...

I tried to connect my Nokia 5300 using the DKE-2 USB cable but it just won't connect to my PC. I've tried checking it on My Computer but it doesn't show up on devices with removable storage. I just want to know if it is compatible with HP Pavillion.

@lilac:
when you connect the phone to the pc, keep your eye on the phone.
On my 5300 the message is: "USB cable conncected, Select mode". Press Ok to acknowledge the message, and you are moved to a menu where you can choose
- "Nokia mode" (= PC Suite compatible)
- "Printing and media" (dunno myself what this is for... RTFM)
- "Data Storage" (= Mass storage device, like an external hard disk)
You should go with "Nokia mode" if you want PC Suite to recognize the phone.
You should go with "Data Storage" if you just want to see the phone's memory card as a disk, and move files to/from as if it were a disk.

USB drives compatible with MAC and Win

Can anyone help me out. I need to encrypt my USB drive but such that it can be decrypted by both my Mac and a Windows machine.
1) If I encrypt the USB drive using the MAC to create an encrypted disk image, will the Windows machine be able to access this disk image?
2) Is there a decent USB drive on the market with encryption software compatible with both Mac and Windows machines?
Thanks for any help (and excuse my Mac ignorance !)

I have the same issue and ended up damaging my USB when Sandisk tried to format it so it can be used for MAC. Its very frustrating that all these big companies can't make MAC compatible software. What's more frustrating is that they advertise their product saying it works with WINDOWS n MAC but when you go check out the encryption software then its only windows compatible.

Firewire & USB Hubs

Hi All
Can anybody suggest a good matching Firewire hub & USB hub to sorta match an
Ali Imac, I am in the UK.
Thanks.

This is probably the wild card solution, but have you considered one of the External Hard Disks designed to match the Mac Mini. The colouring is about right and in addition to whatever backup/additional storage it gives you, you also get a powered USB2.0 and power Firewire 400 hub in the box.
Apparently they fit rather nicely on top of the iMac's pedestal.
I can't find any good ones in the UK but OWC are a great mac supplier and UK buyers have found their prices cheaper even once international postage and VAT is added.

Usb wifi compatible with osx 10.8

Hi I need to buy a usb wifi adapter for my macbook pro 13' mid 2009. The airport card won't work anymore. It's not a problem with airport itself, it seems the problem has something to do with some sort of connection problem between the airport card, bluetooth, the webcam and the mother board, and to repair that connection would be expensive. Does anyone know of any usb wifi adapter which would work with osx 10.8? 150 or 300 MPS? Thank you.

Pages 5 is not compatible with OSX 10.8, or anything else much.
Page '09 is compatible.

Wireless USB Adapters compatible with 10.8

Since updating to Mountain Lion 10..8.2 on my MBP 2008 - 8 gig Ram, the system will not start up when my USB wireless stick is attached. Once I remove it, the system starts up fine. Pop it back in and it shuts down. I can plug other devices including USB music Keyboard, iphone without any problems. Occasionally I can insert the usb stick and wireless actually works but it is intermittent.
I use the stick as the wireless hardware inside the MBP is damaged and have been using it like this for around a year on Snow Leopard without any problems. I also updated the drivers for my USB stick which is made by Realtek.
I repaired disk permissions and reinstalled Mountain Lion before posting this but the problem still persists.
Does anyone recommend any USB adapters that are compatible with 10.8??
Kind Regards

Firewire USB hub/adapter?

Hi
I Need to connect a USB web cam to my fore wire 800 port. Is there any adapter/hub that can do that? The two USB ports my not be used since there is another webcam there wich use all the BUSspeed. Since The firewire port is on another Bus it could be possible if there exist such an adapter/hub. Anybody knows?

I found plenty of USB-FW adapters on Amazon, but none of them worked for anyone. If you know of one that does work, could you please let me know where I might find it?
I need to connect my Canon XL1 to my MBP (which doesn't have FW!). I refuse to buy Apple's Tbolt-FW adapter. I spent a forture on this notebook + I already had to buy a Tbolt-Ethernet adapter + an external DVD drive. This is getting ridiculous.
I looked for an HDMI to FW adapter but found nothing.
I have an old Sony VAIO which has i-link and ethernet. It looks like my only option at the moment. I've had many good macs, but this one is very dissapointing to say the least.
