How do I select a USB hub?

The USB ports on my studio display went out yesterday during a series of power outages. Is the fix as simple as expanding one of the ports on the tower with a hub from Staples or ebay? Will the hub need external power? Are there any hubs out there that are known to work well with the G4?

Sometimes a PRAM zap or a restart will "fix" a USB problem. Also look at the following link.

USB hubs should be universal, i.e., any brand will work. But get a powered one.

How do we know which USB hub is 2.0 & 1.0?????

The two USB ports on your Quicksilver are USB 1.1. To get USB 2.0, you need to install a USB 2.0 PCI card. The external HD will work on USB 1.1, but will have slow data transfers compared to USB 2.0.

Best bet is any card with a NEC PD720100 or PD720101 chipset Stick with the NEC chip, and try NOT to use drivers, Tiger and Leopard don’t need drivers.
All of these Cards are NEC chipset based

How can I make my USB Hub Wireless using TimeCapsul

I have TimeCapsul and I use a 7-port Dynex USB hub. It has an external AC powersupply so it does not need to draw power from what it is plugged into. I would like to take advantage of what apple advertises that TimeCapsul can do, making my USB Hub wireless. However when I plug the hub into the TimeCapsul, the things i have plugged into the hub aren't available. Am i doing something wrong?

The USB port on the TC is used for a disk drive or printer. It doesn't make any other devices accessible. For disk drive or printer you must configure the TC using Airport Utility to share the device, and you need to turn on Printer Sharing and/or File Sharing via the Sharing preferences. Read the manual that came with the TC for configurations.

How do I select NAD USB Audio for Airport Express

I want to pay iTunes from iMac to airport express, optical cable input to NAD 375BEE integrated amp. It requires I turn on NAD USB Audio on Mac. Any suggestions?

I doubt it. All that should be required is to select the remote speakers using the icon to the right of the volume control (in iTunes 11).
It doesn't make a difference whether you use the Express's optical or analog audio output. The streaming audio is not being sent to a USB port.

I can't print wirelessly using Airport Express. I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not.

I've tried several USB connectors, and several different ports on my USB hub; same result. I need to have the HP connected to the hub 'cause from there it's connected to our desktop Mac.

Hi,
I am currently replying to this as it shows in the iChat Community.
I have asked the Hosts to move it to Snow Leopard (you should not lose contact with it through any email links you get)
I also don't do Wirelss printing so I can't actaully help either.

While the many USB adapters seem to be easier to handle, we have had some bad experiences. Their stability is not always up to the task for industrial applications. This might not be an issue when you only use them to control your RS-232 lab equipment for manual experiments, but in our case we have fully automated lab systems running, where LabVIEW controls sometimes up to 8 serial devices and those applications are supposed to run day and night, if possible for many days in a row without interruption. With many of those noname USB-RS232 adapters we noticed various kind of problems. It could range from intermittent communication errors (which could be handled by additional code in our software to retry communication on such errors) to complete failure of the RS-232 port after some time, which could only got back online by unplugging and replugging the USB adapter.
For our purpose this was completely unacceptable and we ended up using ENET-RS232 devices instead which are working fine for months in a row.

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.

How can I get my iPod Classic to be recognized by my laptop through a usb hub?

My new XPS 13" recognizes my iPhone 4 when run through the 3.0 USB Hub but not the iPod. If I connect thhe iPod directly to the XPS iTunes will recognize the device.

recommended only 2.0 usb.

I have BT Infinity at home with the BT modem connected to the phone line and then to a BThub which delivers the wif signal. I have purchased an airport extreme to improve wi fi strength if how do I connect up to hub it states connect modem to WAN on back of Airport Extreme.
Instructions do not mention connection to BT Hub and the BT modem has only one output which you dicsonnect from Hub and connect to airport extreme leaving. Once you do this Hub has no signal.
How do I rectify
Paul

you can also set up the Airport extreme to extend the wireless by hitting the wireless tab in the airport menu then click the drop down menu to select extend
Apple's "extend" function is a proprietary setting that was designed to only work with other Apple routers.
It would be extremely unlikely that this setting would work with a BT product, or any other manufacturer's product for that matter.
But, I haven't tested this with a BT product...and I suppose anything is possible.
Still, I would be extremely surprised if this worked.
The AirPort Extreme might "join" the BT network if you try this......but the AirPort does not provide any additional wireless signal coverage when it "joins" a wireless network. In fact, it really does nothing when it "joins" a network except enable the USB port.

Open Hub: How-to doc "How to Extract data with Open Hub to a Logical File"

Hi all,
We are using open hub to download transaction files from infocubes to application server, and would like to have filename which is dynamic based period and year, i.e. period and year of the transaction data to be downloaded.
I understand we could use logical file for this purpose. However we are not sure how to have the period and year to be dynamically derived in filename.
I have read in sdn a number of posted messages on a similar topic and many have suggested a 'How-to' paper titled "How to Extract data with Open Hub to a Logical Filename". However i could not seem to be able to get document from the link given.
Just wonder if anyone has the correct or latest link to the document, or would appreciate if you could share the document with all in sdn if you have a copy.
Many thanks and best regards,
Victoria

Hi,
After creating open hub press F1 in Application server file name text box from the help window there u Click on Maintain 'Client independent file names and file paths' then u will be taken to the Implementation guide screen > click on Cross client maintanance of file name > create a logical file path by clicking on new entiries > after creating logical file path now go to Logical file name definition there give your Logical file , name , physical file (ur file name followed by month or year what ever is applicable (press f1 for more info)) , data format (ASC) , application area (BW) and logical path (choose from F4 selection which u have created first), now goto Assignment of physical path to logical path > give syntax group >physical path is the path u gave at logical file name definition.
however we have created a logical path file name to identify the file by sys date but ur requirement seems to be of dynamic date of tranaction data...may u can achieve this by creating a variable. U can see the help from F1 that would be of much help to u. All the above steps i have explained will help u create a dynamic logical file.
hope this helps u to some extent.
Regards

USB hub does not work with iTunes

I have been trying to add USB ports to may Mac's and am not able to synch through the hub. They are hi speed 2.0 USB hubs by Rocketfish and Belkin. iTunes locks up until I remove them from the USB cable (spinning color wheel) and then iTunes goes back to normal. I have tried with both my 24" Intel iMac (Metal one) and a new 15" Macbook Pro. When I use the USB port on the Mac iTunes works great. There seem to be a ton of USB problems posted and zero answers on how to correct. I have tried with an Color iPOD, iPhone and an iTouch to no avail. Having a couple of USB ports won't work in my situation. Anyone know if Apple has posted a workaround or a real fix anywhere.

Thanks, I missed where I posted But I tried with my HP - Same issue. I think others have had this. I believe that iTunes is hit or miss on Hubs. I wish I could figure out what makes them a hit - instead of a miss.

Time capsule doesn't see printer through USB hub

I can't seem to get the TC to see my USB printer if it connects through a hub. I have an external drive plugged into the hub and I can plug it into any of the ports and the TC log file shows the disk plug in and unplug. The disk works great.
So far, the only way I've been able to print via the TC, is to connect the USB cable direct to the TC. But there's no indication in the AirPort utility that the printer even exists. Using System Preferences printer setup, I'm able to see the printer, add it and print a test page. At no time did the AirPort utility indicate that the printer was indeed attached to the Time Capsule and functioning correctly.
How do I get the AirPort to give me more log information? I can't believe that I'm able to print via the TC, yet the printers pane is empty, and nothing in the system log.
After doing this test, I again tried using the hub, and the printer is no longer visible on the Mac, but the disk on the hub is there. I unplug the hub and plug the printer direct, and it's again visible on the Mac. At no time does the TC indicate that the printer exists.
I do Linux system admin all day and bought a mac because it runs Unix for command line, and is supposed to be a "no brainer" to manage - a big plus as I really don't want to bring my work home and just use the computer. Sigh....
Macbook is running 10.7.2
Time Capsule is a new 2T unit
Printer is Canon iP4300

The thing that really bothers me is that when I connect the printer direct to the TC, the Mac sees it, but not the Time Capsule... ***?!?
Resetting the print system may...or may not....help here.

You are power cycling the entire network after you make a change in the USB connections, correct?
A powered USB hub will run $15-20 or so. Highly recommended.

MacBook Pro (mid-2010) Internal USB HUB freezes/locks up

MacBook Pro (mid-2010) wilth the latest firmware, etc.
OS X 10.9.1
USB KVM to share keyboard and mouse with another computer
This has been working flawlessly until I upgraded to 10.9.1
The KVM uses the Scroll Lock key to toggle the input between the two computers
I switch back and forth many times a day.
Almost once a day now, all my input to my MBP will lock up when switching the KVM over.
The MBP track pad, keyboard, blue tooth Magic Mouse, KVM mouse and keyboard all become unresponsive.
I am assuming that the interal keyboard/track pad/blue tooth transceiver are all tied to an internal USB HUB.
The MBP is up and running and I can ssh into it. The only error message in the log is that the mouse device coming from the KVM is busy and it will be disabled. I have tried to close the lid for several minutes and then re-open, but it does not resolve the issue. I have tried connecting another USB mouse/keyboard during this time and it will not work. I have tried kill -HUP on the usbd and USBAgent processes. Everything stays unresponsive. The only way to resolve this condition is to reboot the MBP. Note: the KVM works find on the other computer when I switch it back and forth regardless of the state of the MBP.
I am suspecting that when this happens it is some how disabling the internal USB HUB, which if all the other devices are connected through it, nothing no longer works (but maybe I am crazy with that thought). Anyone have any insight? Is there a way to reset the internal HUB short of a reboot?
Thanks in advance!

I'm seeing the same problem with a 2010 Mac Mini with IOGear KVM and MS wireless mouse. This setup worked flawlessly for years on Snow Leopard but started hanging soon after the Mavericks upgrade. I'm running 10.9.4, currently the latest release. The system usually hangs after a KVM keyboard switch from Windows on the other set of KVM cables back to the Mac Mini. ssh into OSX works fine but a shutdown hangs indefinitely. top showed no processes spinning. The 1st console message after the hang was:
8/6/14 8:49:21.000 PM kernel[0] USBF: 1317978.201 AppleUSBHubPort: Port 2 of Hub at 0x6200000 about to terminate a busy device (Microsoft® 2.4GHz Transceiver v7.0) after waiting 10 seconds
There were no other messages for hours before this. I'm using VM Fusion but I think it hung once without it running. The Windows 7 side of the KVM works fine.

DELL 2713 USB hub Issue on MacBook Pro Retina 15

Hello,
I have a new MacBook pro retina 15" and Dell 2713 monitor.
the Dell works fine with the MacBook with supplied DP cable.
BUT the USB hub doesn't work, the monitor is connected to the computer with original dell usb 3.0 cable.
Note: on PC & win7, it works fine
How can I find a proper drivers for this built-in USB 3.0 hub.
thanks,
Tomer

The Retina models are full of flaws. You have found one of them. For some reason the discrete graphic card is being shut off in Windows and you are now using the built in Intel HD Graphics 4000. Why I have no idea.
