Trust Curve 7 Usb Powered Hub

Hi guys
I have bought a new usb powered hub, the Trust Curve 7.
It's look nice but it doesn't work properly.
The only way to make it work is to connect the hub without the power supply and only AFTER connect the power supply.
I think this thing isn't normal and i doesn't like this problem (ok it isn't a big problem but...)
Any IDEA
P.s i'm running OSX 10.7 on a macbook pro 13inch late 2011 (i5 dual core 4 gb ram)
I've try the hub on a windows computer and it's work well
Regards Andrea

Hi Schooner17-
Are the drives bus-powered?
If so, do they work with the hub on a Mac? Do the drives work 1 at a time?
That hub might not supply enough juice to power both drives.
Luck-

Any USB powered hubs that DO NOT prevent Sleep???

I have a Belkin powered usb hub.
whenever it is attached my computer will not stay in sleep mode.
keeps waking up whenever i try to put it to sleep.
deos anyone know of a usb hub that does not do this??
thank you!

I have nothing but Belkin hubs (both USB 1 and USB 2) at home and work and none of them keep my computers awake. It could be an isolated incident with your hub, it might be one of the cables (that happened to me at work and drove me half nuts!), and it might actually be one of the peripherals you have connected to the hub.

Intel imac won't boot with usb powered hub attached

My intel imac has started to not boot with a powered (have tried a variety of them) attached. Just stops at the white screen. Also, after I attach the hubs (2, both powered) the computer got into spurts when it just kicks everything attached to the hubs off saying that something pulled too much power. At other times it is fine with the same set up. I've tried resetting the PRam but it didn't make any difference.
I see from other postings that this isn't too uncommon, but didn't see any fix.
Thanks

Can you determine if it is just one of the hubs? Resetting the PRAM probably didn't have anything to do with this problem but the SMC controls the power, try this reset:
SMC RESET
http://support.apple.com/kb/HT3964
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.
The 5 second timing is important to a successful reset.

USB Powered HDD fails - Alu iMac 2.4GHz 21 inch

Hey folks,
I have an aluminium iMac 2.4GHz 21 inch model.
I have been using externally powered USB and FW devices for a while and had no issues. However, I just picked up a USB powered HDD and it cannot consistently transfer data. This same drive works perfectly on my Dell laptop, and I tried another USB powered drive from a friend (which I also know works) on my iMac and it has the same problem - cannot do any sort of mass data transfer.
I have a powered USB 2 hub (4 port Belkin) and obviously three ports on the iMac.
I also have two externally powered drives, both of which work fine.
It appears that any transfers from the INTERNAL drive to a USB Powered drive work ok, but any significant transfers from a USB drive (externally powered) to the USB powered drive FAIL.
I have tried plugging the USB powered drive into the iMac directly, and into the USB powered hub, no difference.
I suspect that the USB on the iMac just cannot handle either the power requirements or the data throughput requirements.
The external USB powered drives are:
Western Digital Passport 250GB.
Iomega Select 500GB.
Any hints? Or is this desktop machine just not made to work with USB powered devices???

If your two powered external drives are always connected to the iMac, you should really reformat them to +Mac OS Extended (Journaled)+, and not use a Windows format. There are other limitation to FAT32, because it is an old file system from a time when hard drives were very small. One is that data is not stored as efficiently, so the same files (especially if there are a lot of small files) will take up more space on the drive. Another potential conflict is file naming convention; an allowed file name on one may not be allowed in the other (between a Windows format and a Mac format). There is also no journaling with FAT32, which is a feature that helps with data corruption issues. There are probably other disadvantages to using FAT32 on a Mac.
As a test with that external USB-powered drive (the one you own), you should use Disk Utility to reformat it to a Mac format. Then, try the file transfer again. If it works, then the cause was the existing formatting, although the exact reason may not be clear. If you need it to be FAT32, you can try using Disk Utility to format it as +MS-DOS (FAT)+. Maybe if the Mac does the formatting, it will resolve this problem, even it is still formatted as FAT32 (and it should still work on a PC).
When going from Mac format to Windows format on the entire drive, you may want to use the Disk Utility Partition tab, and not the Erase tab. On the Partition tab, reset the +Volume Scheme+ to one partition. Click the Options button and it will show the three possible choices for +Partition Map Scheme+. When you format it as +MS-DOS (FAT)+, select +Master Boot Record+. When you format it as +Mac OS Extended (Journaled)+, select +GUID Partition Table+.

External USB 3.0 Powered Hub?

I need a recommendation on which USB 3.0 powered hub I should purchase to go with my MacBook Pro 9,1. I only need 4 ports. The main purpose of the hub is to power a Matrox DualHead2Go display adapter. Quite frankly, the device is only USB 2, but I figured I might as well get today's technology. Any advice is greatly appreciated.

Yes, I know where to get them. What I wanted to know was which ones work best with the MacBook Pro. Believe it or not many of these devices have issues with Apple products for whatever reason. Just check the amazon.com reviews.

Hi. I have the Apple connector kit...and actually played Garageband via my M-Audio Oxygen 25-keyboard thru my iPad2--without a powered hub.
But that was two month ago.
Now...I can't get it to play--with volume. I can hear the notes...but faintly. And I have pushed ALL possible volume controls up (Keyboard & iPad).
I know the keyboard is triggering, because I tested it on a MacBook: got full volume, just like before.
But just can't get full volume from the iPad2. I got a 4-port USB hub...and tried interfacing it between the keyboard and the connector kit/iPad2. But still no volume. It's almost like a switch is off in the iPad???
Any help would be appreciated. Dan

hello again,
i didn't really dare to delete the blue home folders before, just in case everything went wrong, but now i think i have so little space that i can't afford to lose 2.25gb!
one thing that slightly worries me is the fact that the 'proper' library folder (in the home icon) is 2.09gb, whereas the 'wrong' one (from the blue folder forenamesurname) is 2.24gb - this is the one i would be deleting. just seems odd to delete a larger file than the one i presume i'm using.
"Move everything you want to keep out of the blue folders, and then place both of the folders on your desktop. If everything works properly after a few days, delete both folders. If you are asked for your administrator password at any point or if either folder is copied instead of moved when dragged, don't delete that folder."
by 'everything you want to keep', does this include the library folder? 'cause there doesn't seem to be much else, and i'm not sure if deleting the library folder would ruin all my preferences.
i've put both of the folders on the desktop, it didn't ask for the admin password or try to copy them, so i guess that's good news. what kind of things should i be looking out for to act differently?
are the folders not in use now that they are on the desktop?
also if i put them in the trash will they have no effect? i.e. the same as permanently deleting them, so i could put them in the trash as a test.
cheers, stephen.

Satellite P750 - Shutdown issue after removal of external monitor USB 3 hub

Have operated my Satellite P750 laptop with external DeII monitor for a year or more now.
Monitor has a Usb 3 hub. (i have some ext HDD plugged into these. So far no issues. I unplugged the monitor usb hub from laptop (to create wndows image backup straight through the sole usb3 port on laptop.
After this finished i found that i was unable to shutdown or restart laptop. It gets to the light blue 'shutting down' screen; HDD light flashes for 5/10 secs then it stops accessing disk with power still on and stuck at blue shutdown screen; laptop even sounds like it shuts down.
Two things, i can hold down power button till hard stop, then press again to restart, and all is fine; no error messages when win 7 start up again. Or i have once just left it sitting without holding power button- it seemed to be like this for about 4 hours (monitor went to standby cause idle) before powers down.. When i start laptop after this i get windows warning failed to shut down properly.
It took me a while to work out which device was causing the issue; but can now replicate any time.
So - unplug monitor usb hub from laptop; laptop fails to shut down/restart.
Replug DeII usb hub back to laptop; no problem laptop back to normal shut down.
Any ideas??? (this means whenever i go portable with laptop i have to hard shut down/ hold power key to turn it off????)

To be honest I dont know why the system cannot shut down properly without connected USB monitor hub but system shut down issues are mostly related to some processes which are running in the background.
Sometimes such processes are locked and could not be closed due to different reasons. This may prevent the system from shut down
Maybe this is the case
Try to clean the system as well as the registry using CCleaner (its freeware tool).
You should also check what processes are running in the background maybe one of this processes is related to the hub which cause your shut down problem

Belkin MacMini 6 Port USB/Firewire Hub F5U507

Does anyone have the Belkin F5U507 6 Port MacMini USB/Firewire Hub?
I want to buy it but I'm hesitating, being concerned that it doesn't have its own AC power unit to attach to the wall socket.
It does look nice, matching up to the Mini, but I don't want it to be a case of more form than substance.
Any recommendations?
Thanks.

Well, this may be an "oopsie" for me then. I just purchased this hub a couple of days ago from the Apple store (my powered Belkin hub - the lozenge-shaped one - just failed).
I was wondering how they got around the fan-out issue with the new hub being unpowered. Well, I have time to cancel the order.

Audigy 2NX USB Root Hub Prob

Hopefully someone here will have some suggestions to help resolve my issue.
I have fi've USB Root Hubs on my computer; the USB system is 2.0
Only two of those hubs are in use. One hosts my Canon scanner.
The other hosts every other USB device on my system.
That in itself is an issue, but because not all of my USB devices are in use simultaneously, it hasn't previously been an issue.
Now, however, it has become one.
Both my Audigy 2NX and a four-port self-powered USB 2.0 hub are on one USB Root Hub. The four port hub has my two printers connected to it.
The issue is that when I use my laserjet printer, it disables the Audigy 2NX. The Audigy normally comes back up after the printer has gone back into sleep mode.
However, if I am playing a game when the printer is used (I share it on a wireless home network) it disables the Audigy and it can only be brought back up by restarting the computer.
I think it is one of two issues;
. The four port hub with the printers on it cannot share a root hub with the Audigy 2NX; when the laserjet comes out of sleep mode, it uses all of the bandwidth on that root hub and disconnects the Audigy.
2. A recent driver update to the Audigy is conflicting somehow with the printer.
I might also be tempted to think it was a power supply issue if I didn't have a robust 650 watt PSU on my system.
To try to get the two devices on separate root hubs, I turned off my computer and disconnected all of my USB devices. Then I connected one at a time, powering down in between connections.
The device assignment remained the same.
My next step is to uninstall the Audigy 2NX completely from my system, and then re-install from the base drivers.
My question is; does anyone know how to force devices to install to a specific and/or different root hub outside of their physical connection? An .ini edit or perhaps a driver edit's
Thanks in advance for any help.

I have an Audigy 2 NX myself, and I found it works best off of a direct root usb port (not off a hub). The problem is that on most computers 2 USB ports share hub. Which is why you are having that comflict.
My conflict doesn't happen there, it was on the mouse at first, now it's on an external IDE Adapter i'm using.
All I do is unplug the IDE adaptor when it stops working, waiting a few seconds, then plugging it back in.
So what I suggest is to do like I did, and switch what ports things are plugged into until it's something that can plug & unplug with no real issues.
Why this happens, in opinion, is that there just isn't enough power getting to all the usb ports when there's alot of stuff plugged into them. My limit seems to be 7 items, even though most of them are lower power stuff, mouse, joysticks. I do have a 3.5" hd in a case, which is self powered, and the ide adaptor which is self powered, and the audigy 2 nx, which is, as you know, self powered. I can plug another item in, but anymore after that will knock my ide adaptor. and i still have usb ports i'm not even using. oh, the joysticks are on a hub which is where I usually plug another item in, either my mp3 player or thumbdri've.
I think it most likely an electric problem, and that it only affects people with faulty usb componets or something. I haven't heard of it being widespread or specific chipset/usb controller problem. Can't think of anything else it could be, but i'm not an electrition.
Sorry i could be of much help, but maybe you can at least make it less of a bother to deal with.
good luck

USB-C Hub/Dongle issues with new MacBook early 2015

With the new MacBook that has the single USB-C port I find these results and would appreciate any comments:
I purchased an Apple dongle that has 3 ports: USB-3, HTMI and USB-C. I also got a new Belkin 'USB-# / USB-C" 32 gb Flash Drive.
With this dongle (hub?) I can utilize a USB flash drive or USB 500 gb HD via the USB port while charging the MB
I can use the new Belkin USB-C/USB-3 flash drive in the USB port while charging, too
BUT if I remove the charger and just plug-in the Belkin Flash Drive on the USB-C side to the USB-C port on the Apple Hub -- NOTHING NOTE: The Belkin 2-size Flash drive works fine in USB-C mode if DIRECTLY connected to the MB
I also purchased a Belkin USB-3 3-port hub with 1 more port - an Ethernet port. (Note: This is an UNpowered hub - no transformer, power comes from the Mac)
This works great if all 1, 2 or 3 USB ports are being used with Flash drives of 500 mb to 64 gb in size.
But if I plug-in a SLIM 500 gb USB-3 HD (not an SSD) - then if there are any flash drives in the other ports, they immediately lose power and are "ejected" - and I get a warning message. So it seems to use a true HD with a USB Hub it will have to be a powered hub. (I returned the other for full credit and have not yet purchased a powered hub because frankly, I want something portable - so don't plan to do that experiment myself)
So would this hub have worked with a MacBook Pro or iMac? Is it just that the new MB-2015 model doesn't supply enough power? (Maybe, I think - but not so sure).
Same result with a 4-port Targus USB-2 hub I use on my MBP-2010. I'll test that on the MBP with the 500 gb HD tonight.
OK so just wondering if there is anyone out there with similar experience(s) using either the new MBP or in general with HD's and Flash Drives utilizing powered and unpowered USB Hubs. And the first question about why the Belkin Flash works from the USB-3 side but not the USB-C WHEN UTILIZING THE APPLE HUB/Dongle. (The Belkin 2-size Flash drive works fine in USB-C mode if DIRECTLY connected to the MB).
Thanks very much.
Best regards,

To add. The following note appears on the Apple store site pertaining to T-tech's mobile USB Disk: "Note: The G-Tech G-DRIVE mobile USB 3.0 Hard Drive is not compatible with the Apple USB-C Digital AV Multiport Adapter or USB-C VGA Multiport Adapter."

Will powered hub allow both a external hard drive and printer?

I have a 500g airport purchase in June 2009. I believe apple updated the products shortly afterwards. I am not home so don't have the model number. It has one USB port. Connecting one printer has worked with no problems. I just bought a 1T external hard drive and connected both the drive and printer to a powered hub. The hard drive is discovered by the airport but not the printer. What am I doing wrong?

Have you power cycled your complete network?
If not, power everything down, order is not important. Then start the modem first and let it run a few moments, then start your AirPort Extreme, then your hard drive, printer, and computers one at time, waiting a moment or two between each device.

Does anyone have a USB powered external hard drive that works?

I bought a really slick USB powered hard drive to take with me when I travel. The whole reason for purchase is to have it power off the laptop. It works on all the Windows machines, but my Mac doesn't even know the drive exists unless I first plug it into a powered USB hub. If I plug it directly into the USB port on the laptop, nada-zip-zilch.
This doesn't fit the plan I had.
Any help? Anyone need a slick little hard drive? 8-)

Hi Kitty, I have a lacie porsche designed drive that works with out a hub, but it needs to use two usb ports to mount on the mac. not ideal but portable enough for me

Powered Hub

when connecting a powered hub to my macmini's usb port, i notice that the power indicator on my macmini gets lite even no power is applied to the mac. does this normally happen? as of now i dont use the powered hub as it may cause me my mac mini.
thanks

If it's plugged into the wall, then the fact that it charges your iPod only means that it has power. That's all that's required to charge the iPod.
I would double-check the cable that runs between the hub and your computer. Make sure it is fully connected and plugged-in all the way.
Also, try another USB cable between the Hub and your computer.
And, try plugging the Hub into a different port on the computer.
If none of that works, take it back and get another one.
I hope this helps.

3 USB ports missing +5 Volts., HP X18 1027CL Laptop, Win7, USB powered cooling fans, no message.

Has anyone else seen this before. I have been using this process to supply coooling to the laptop for a long time, but today the cooling fans quit and now none of my USB ports will recognize any of my devices that require +5 Volts.

You should have used the cooling fans with an externally powered hub. You may have fried some of the traces going to the Southbridge chip on the system board of your notebook. This limit for a USB port is in most cases 500 mA. You may have exceeded it.

Usb 2 hubs that work with 5gen

Which USB 2 hubs (Specific brand model) will work with the IPOD 5g with the Imac g5s?
I bought a Dlink self powered and it wont see my ipod 5g.

I just bought and used successfully a self-powered Tripp-Lite Ultra-Mini USB 2.0 Hub 4 ports (model U222-004-R). This solved my problem of the USB port timing out when loading large numbers of photos. Today I was able to download all 7961 photos and their originals to my ipod in one transfer!
