Usb hub not working (worked with G3)

Help! I have a wonderful GE brand 4-port USB hub, which I used for several years without a single problem with my old beige G3. It plugged right into the USB port and everything I plugged into it popped right up and worked fine.
On my new iMac, nothing will connect through this hub. The peripherals work great when connected straight to the computer, but not through the hub. I've perused several forums, but to no avail. Anyone have this problem or know what I need? Does it have to do with the Intel processor? GE will not help, saying it is an Apple issue (since it worked fine before).
Thanks in advance,
Jen

Does your new mac have a USB port in the keyboard that you're using? That port has not supplied enough power to ork with devices that need to get power.
Can you plug it into a different port in the iMac? Side of the monitor have a port?
Can you confirm that this little hub really does still work? Got the old G3 still hooked up somewhere?

Belkin Network USB Hub not working with new BT Rou...

Hi,
I received my new hub to use with Infinity when they turn it on in a few days time.
I connected the new router to the ADSL and all works perfectly without any set up needed.
I installed (on my old 'sheep-dip' PC) the BT software, and now this test PC will not connect to any USB hard-drives or Printers connected to my Belkin Network USB hub.
The Network USB hub works fine with all the other PCs in the house - but not if I install the BT software.
(Which appears to be mainly adverts and a link for those too dim to type BT.com in a browser... ;o)
I am guessing that this may be something to do with the software blocking use of the new BT Router using its own USB socket as a Network USB link - as this is being saved for 'future product enhancements'. Is there anyway of curing this and still having the BT software on this machine?
Thanks!

Is this issue likely to go away when the Infinity service starts? - I am guessing not?

Whats wrong with this mainboard ?! system reinstall does not help...

Hi @pheonix1 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv6-6b15ew Notebook and issues with the Fingerprint Reader. Here is a link to troubleshoot the Fingerprint Reader.
I would just start at the top and work my way down. Enabling biometric support should resolve this issue.
Please let me know how this goes.
Thanks.

USB-Hub not working on LEFT USB port?

Hello,
I have installed Windows 7 Ultimate 64 Bit on my MacBook Pro 13" Retina (Early 2013) and it's running fine. Boot Camp version: 5.0.5033.
But I have one problem: I bought an external monitor (Dell U2414H) which has an built-in 4-Port USB 3.0 hub. So I connect the Dell monitor using a DisplayPort 1.2a cable and an USB 3.0 cable. But Windows only recognizes the monitor's built-in USB hub when I plug the USB cable into the right USB port (when I sit in front of the MacBook). Then it works without problems. But when I plug the USB cable into the left USB port of the MacBook Windows only says "USB device not recognized". But other devices like USB sticks and USB drives also work without problems on left and right USB port of the MacBook. Also when I boot in OS 10.9 Mavericks the monitor's USB hub is working on both USB ports of the MacBook. So I think it isn't a hardware failure. I also re-installed Windows, but I have still the same problem.
Do you have any idea, why only the monitor's built-in USB hub is not working in Windows on the left port of the MBP or even how I could fix it?
Is Boot Camp 5.0.5033 the most current version? I checked the box to download the latest Windows support software and also didn't find anything newer than 5.0.5033 to download, but sometimes I read about 5.1.1 - but where could I download it? AND: Doest it help?
Thanks in advance!

I think I've hit a variation on the problem you're enoucntering. I have a late-2013 13-inch Macbook Pro Retina. I've just installed Boot Camp and a copy of Windows 7 Pro. This is my first experience with Boot Camp and Windows on a Mac, so I'm in foreign teritory.
The install all went fine and Windows 7 booted up fine and so far, all hardware seems to be working as expected, with one exception. Things went sideways when I tried use it in "clamshell" mode - lid closed with external monitors and all my peripherals attached to a USB hub. I set up Boot Camp to boot into Windows and attempted to boot. It would give me the usual boot-up fanfair and a then a gray screen for a few seconds, and then it would reboot. It just rebooted over and over. I eventually discovered the issue was the USB hub - without the hub connected , it would boot just fine. Once it was booted into Windows, I could attach the the hub and everything would be recognized normally. Furthermore, I could put the system in sleep mode, wake it up and everything would be working fine. But it simply refuses to boot the USB hub attached. I've stumbled on a couple related threads - see https://discussions.apple.com/message/23802231#23802231. The suggestion is that only certain hubs to not work. I've got two different high quality powered hubs and both display the same behaviour. The other point is, that when booting into OS X with the same hub, it works perfectly. So it's a strange problem.
Note that after reading your post, I did try the hub in both right and left USB ports and that made no difference in my case. I do have one more hub to try (built into my Dell monitor). I'll report back if that happens to work.

USB Hub not working

I have a hub which has worked fine but is now no longer working. A light on it still lights up and it is recognized in System Profiler. Also items plugged into it are also recognized in System profiler.
Any ideas?
Thanks
John

Have you tried a new USB cable between the computer and the USB hub?
And if another USB port than the one being used now, has not been tried
to see if the issue is in one port on the computer, and not another, try it.
Also, sometimes the lights are on, but nobody is home. The hub can be
bad and still appear to be there.
{Have you tried the computer with only the keyboard and mouse attached?
If that works OK, then consider the limits of port power to run other USBs.
Then, a new powered USB hub may work, if the Mac's ports aren't bad.}
There may be a low-power situation (assuming USB hub is powered) that
somehow does not translate into a notice or 'warning dialog box' on screen.
Perhaps one of the connectors in a USB cable or in the computer's USB
ports, necessary for data flow, is not working correctly?
At one point, I'd bought a two pack of powered USB hubs; to find one of
them did not work right out of the box. It was un-powered, yet the AC
adapter supplied adequate power. Items appeared in Sys Profiler, yet
if more than one were used, the Mac's ports could not sustain them.
The package was such a low price, I kept the working one; the store I'd
bought them from no longer had any in stock. The good one still works.
Have you tried to reset the SMC or 'power management' unit device?
This may be a last effort of desperation & signals a service tech visit.
Good luck & happy computing!

USB Mouse not work with Mac OS 10.6

I have a USB mouse can work with Mac OS 10.4 but cannot with Mac OS 10.6. Noticed the different is the USB mouse motion reporting is 12-bit instead of 8-bit. It can definitely work on Windows with standard USB HID driver. I wonder if the OS 10.6 is having a different USB HID driver specification which is not posted in USB-IF.

Ask the Vendor.

USB superdrive not working with Mac Pro

Is there a trick to getting a USB Superdrive working with a Macpro?
The drive in the Macpro no longer ejects and have tried connecting the USB drive to both the front and back ports - does it not work with Mac Pros?
Any pointers in the right direction would be much appreciated.

I had a problem my superdrive. It would play dvd's and cd's that were already burnt but would not burn blank DVDs or CDs- in the recent past it had no problems burning. In addition, the Finder would not display the superdrive. When I put a blank disc in it would go to Disk Utilities and would not allow burning. With help from Apple I discovered the problem-- The settings in CDS & DVDs had been changed from When you insert a blank DVD/CD "Ask what to do to to "GO to Disk Utilities". If this sounds like your problem try changing the settings to this:
Try going to; System Preferences/ CDs & DVDs
Change these two settings to this:
When you insert a blank CD: Ask what to do
When you insert a blank DVD: Ask what to do
NOTE: If they are already set to this you probably have a different problem. If they are set to Go to Disk Utilitiy this is probably a solution.
And
Then go to Finder Preferences
Make sure that under "Show these items on desktop:" that the checkbox for CDs, DVDs, and iPods is checked.
Try to burn the DVD again (reload Disc- perhaps restart) and try again.
Don't know how these setting changed but they did. It worked for me.

USB hubs quit working with 10.7.2

I have a Mac Pro, dual quad-core 2.8GHz Xeon, 10GB ram. Three D-link DUB-H7 usb hubs. After the update to 10.7.2 and iTunes 5.0.1 (not sure exaclty when), my usb devices & hubs quit working properly. For a while they would work occasionally.
I have a USB keyboard which works if it's plugged in directly when the computer boots. But other devices (external drives, flash card reader, iPod dock, USB display) don't work at all. I tested the hubs with another Lion system, and they work on that. iTunes wireless sync quit as well.
I've tried resetting PRAM and SMC. Neither fixed the problem. Tried repairing permissions. No change. Rebooting (many times).
Could it be a USB driver conflict? I removed VirtualBox usb drivers, as well as Parallels, but not vmware, which I also own.
When I plug in a device, I get 'trouble enumerating' and then "The IOUSBFamily was not able to enumerate a device." in the system.log
Any ideas? Is my motherboard dying? If so, why does the keyboard still work, and nothing else?

Followup info. I reset the PRAM and booted into 10.5.1, on another drive.
This time, similar behavior; HID devices (keyboard, mouse, bluetooth) work fine. Hubs (which work fine on another Lion computer!) generate a bunch of console errors:

Acer C710 - USB Ports not working with patched kernel

I have an...
Acer C710-844G01ii
I have replaced the original SSD with a Mushkin 120GB SSD (MKNSSDCR120GB-7)
I've used John Lewis' script at https://johnlewis.ie to flash the firmware. It works great. It loads 64 bit dual arch iso (2014.10.01) written to a USB flashdrive (Well, I'm actually using SD card in a USB reader. Not sure if that makes a difference) without having to utilize the workaround listed on the Chromebook wiki page (https://wiki.archlinux.org/index.php/Ch … stallation). I just create a regular arch bootable usb and it seems to work fine. I can use the bootable USB tools. I can install arch to the hard disk fine. (I did this a couple of times on the original SSD that came with the chromebook before I replaced it, so I know it works without having to change the SSD).
The problem I'm having occurs after I install the patched kernel (linux-chromebook-3.16.4-1-x86_64 or linux-mainline-chromebook-3.17-1-x86_64 I've tried them both. Both times I wiped the hard drive and went through the entire install process from scratch). After booting, everything loads up fine except that I lose functionality of my USB ports. The custom BIOS still reads the arch bootable USB if I choose to boot into it. If I boot from the hard drive though, as soon as the patched kernel loads, the USB ports are not working.
The output of
dmesg | tail
is the same before and after inserting a flash drive into a usb port.
Running the command
lsusb
gives output
unable to initialize libusb: -99

Updated the system, now using arch kernel 3.17.1-1
Problem still exists.

USB Ports not working with specific devices

So this one has me scratching my head. My USB ports on the back of my iMac are working except for a few devices. 1 being a logitech USB receiver, and 1 being a usb mp3 player. When I plug the received into the iMac the keyboard won't work, but when I plug my USB hub into the same USB port and the receiver into the hub it works fine. The mp3 player isn't working in any usb/hub (so that's a mook point).
Here's what I've tried to resolve this issue:
1. Reset iMac
2. Reset PRAM
3. Try every usb port on the back of the iMac
None of these have fixed my issue. Plugging it into the hub isn't a huge deal, but I'd like the option to use my USB ports as I wish without having to deal with this. Anyone have advice on a solution?

It is not a matter of using your USB ports as you wish, it is a matter of what you are plugging into them and the power demands that what you plug into them makes on the system.
Not all USB ports or devices are created equal. How many ports are you using? What exactly are you plugging into the ports? What is the power demand of each item that you are plugging into each port? Are any of the USB devices self powered from their own separate power supply? Are all of the devices dependent upon the iMac for power?
It sounds to me that you have too many high power devices demanding more power through the ports than the iMac can accommodate. Is the USB hub self powered? If so, that is probably why it resolves your issue with the Logitech Unified receiver. There is very little info on this device on the Logitech website, so I could not ascertain its power demands.

Need a USB hub to work with a multifunction printer

Can anyone recommend a reliable USB hub that can work with the HP Officejet J4580 Multifunction (fax) Printer? I bought a Belkin 7-port hub for my G4 FW800 laptop (OS 10.3.9) and it works with an older dedicated printer and a 2-year-old multifunction printer (no fax), but I just got a new Belkin 7-port to go with the same laptop and it won't work with the new multifunction, so I'll have to return it.
Any suggestions for a 2+ port hub that's reliable and would work with this new printer? AC- or laptop powered doesn't matter, though I'd prefer to have the AC option. Amazon's web page on this says it will work with all 1.0 and 2.0 USB devices, but obviously that's wrong, and I like not to make the same mistake twice. Thanks!

I'd have to agree with motsteve too.
Stay away from unpowered hubs, they are nothing but trouble or should I be more diplomatic and say that they do work for some devices but not all and some unexplained behaviour has been known to happen with them.
The same can be said of bus-powered hard drives.
Are you sure it is not a driver problem ?
Are you sure this MFP is compatible with the OS you are using ? Have you checked the system requirements first ?
I think the USB hub you have is probably fine.
If it is USB2.0 compliant and is mains powered then there is something else at work here.
1) Check the cables - try another if you have one.
2) Unplug the printer , turn the computer and hub off.
3) Reconnect everything and then turn on first the printer , then the hub , lastly the computer.
4) If 3) fails ,do the same again but in a different order.
I have had problems with peripherals not showing on the desktop or getting a " Can't connect to device XXXX " so I have turned everything off, unplugged them all, then reconnected and turned everything back on.
Once that peripheral is mounted once I generally find that I don't have a problem with it again.
I think it may lie in the order that the OS extensions load or something along those lines.

Usb mike not working with mac mini

Hi,
I bought a samson CO1U usb connection mike to use with the mac mini as there is no mike connection. The device is recognised by the computer but apparently not by i-movies or Quicktime Pro 7 as when I bring up the audio screen nothing registers in the sound level and obviously nothing records - am I doing something wrong or missing something out or is this device just not compatible? Apple help were no help!
Hope someone can be of assistance in this matter as I need to record a voiceover on to an animation video.
cheers, shadwell

Hi, thanks for your reply - did that but still no joy.
In utilities / audio midi it says output ( and input ) not supported and in system preferences/sound the input level is registering nothing.I'm going to try the mike on a friend's laptop to see if it is a problem with the mike or the mini mac - or maybe I'm just making some simple mistake in setting it up in Quicktime.Do you know if any usb recording devices actually do work with the mini mac?
thanks, shadwell

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...

USB Hubs not working

Hi
I've been trying to connect a usb hub to my iMac and have tried all types of brands (Belkins, unknowns) and none of them seems to work. There's either no connection at all, or it works for a day or two then it starts to disconnect intermittently. I'm at wits end. Any advice appreciated. I'm just trying to connect a printer, iPod and mini-usb cables to the hub to sync my devices. Thanks.

I agree with the other poster that you need a powered USB hub. I've been using one from Cable to Go for about 6 months now and it works great, have never had an issue with it. [Click Here.|http://www.amazon.com/Cables-Go-Port-USB-2-0/dp/B000IZDN60/ref=pdbbs_sr2?ie=UTF8&s=electronics&qid=1219431869&sr=8-2] There are various others available I just like this one because it's small and sleek.
