Convert USB 3.0 to USB 2.0? Why?

Sounds useless, since most USB 3.0 devices are backward compatible. But apparently there's enough slop in the spec so that at least my 3.0 HD won't work with my Netgear WNDR4000 N700 router's USB 2.0 port, and I can't mount it as a network drive on my Macbook Pro Retina. You'd expect that the compatibility is achieved by some part of the doohickies ignoring the 3.0 connections and shuffling control signals to their 2.0 counterparts. In any case, the Netgear's not smart enough to do that or something.
Ideally, what I'd like is to have my USB 3.0 HDD plugged into the router so I could do wireless Time Machine backups like a Timecapsule, but take that portable 3.0 HDD along with me and do wired backups and restorals with the speedy 3.0 interface on the road or when I had to do a full restoral. I've tried to fake out the thing by putting a powered USB hub in line, but there's apparently something the Netgear is looking for that the 3.0 HDD doesn't send to allow me to mount that drive wirelessly through the Netgear.
Is there a "smarter" hub that might make the Netgear happy with my portable HD? Or a USB 3.0 to Ethernet converter or someting? I don't expect to find a router with a USB 3.0 interface, considering that extra speed would be wasted going through the wireless interface.
How can I get a drive to be a 2.0 to use it wirelessly via the Netgear, yet 3.0 when I wanted to use it wired directly to my Macbook?
Any ideas?
TIA!

USB3 is totally independent of USB2. The USB3 host sockets provide both USB3 pins and USB2 pins. USB2 also provides compatibility with USB1. When USB2 and USB3 connections are mated only the USB2 pins connect. When you use a USB3 extension or hub, the USB2 and USB3 signals are routed/buffered/split independently.
A USB2 device can thus be plugged into either a USB2 or USB3 host socket with no problem.
A USB2 compatible USB3 device ditto, but if only USB3 is implement the USB2 can't host.
However, I believe USB3 devices are meant to provide that USB2 backward compatibility.
There is a market/standards hole at the moment for actual conversion between USB2 and USB3, either way.
I haven't been able to find any device that does this - the so called converters just route USB2 signals as needed.
I would like a USB3 to USB2 hub or extension that IGNORED the USB2 host interface and uprated USB2 devices to USB3 signalling - this is dead easy and allows (say) 8 USB cameras or memory sticks to get full high speed USB2 bandwidth from one USB3 controller. But for your inverse problem, there would need to be some more complexity, negotiating the lower bandwidth available and/or buffering and/or handshaking for flow control.
Note USB3 is full duplex, so you have the bandwidth in both directions (so the 8 USB2 cameras could store data back on USB3 disks), whereas USB2 is half duplex (one way).

No you can not.
You can connect USB 3 components to you MB if you wish to use them but will only run at USB 2 specs.

Converting a snapped image from usb webcam to rgb model color

Hellow everyone,
I am trying to convert a snapped image using usb webcam to RGB model. I have two VIs, for snapping and the other for converting JPEG to RGB as the attached VIs bellow. My problem is how to connect these two VIs in one VI to make direct conversion from snapping to RGB model. I am using LABVIEW 8.6
Attachments:
NI-IMAQ for USB Snap LV 86.vi ‏43 KB
GetRGB_LV71.vi ‏30 KB

So the two VIs that you have are not directly compatible with each other. Notice that the first one uses IMAQ VIs (an add-on), while the second is using VIs from NI's Base Package. This means that the first VI (the snap) outputs an "Image" type, while the second VI is using an "imagedata" type.
To clarify, you want the histogram of each color in the image, is that right? This is what a histogram is:
http://zone.ni.com/reference/en-XX/help/372916J-01/nivisionconcepts/histogram/
If so, you can use the IMAQ ExtractColorPlanes VI to extract each individual color plane...
http://zone.ni.com/reference/en-XX/help/370281M-01/imaqvision/imaq_extractcolorplanes/
...and then you can use the IMAQ Histogram VI to map the histogram of that color plane.

IPhone 5 micro USB conversion to standard USB for car iPod input.

My car has a USB port for iPod, but my iPhone 5 micro USB won't fit. How can I convert the micro USB to a Standard USB?

It works now, must have been user error. Any suggestions on getting Pandora to work using iPhone 5 on my 2013 Honda Accord EXL? I downloaded the Honda Aha App, but still didn't work. Previously had a Droid X that worked slacker radio and Pandora with no problem in the car.

How to use iPad (4th gen) to edit with iMovie - but using an external source such as a USB stick or external USB hard drive

Want to use my iPad (4th gen) to edit a movie using iMovie - easy enough if the movie file is on the iPad - but what if it's too large - can I keep the source file on a USB stick or external USB hard drive and edit from there? How can you do this?

You can't export any type of file using the camera connection kit, so a USB flash drive or SD card won't work.
There are some wireless external hard drives that can be used with the iPad.
The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.
Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its wireless connection. You can actually fit up to 300 HD movies on it.
Another option:

Why do USB drives plugged into USB hubs make my Mac Book Pro (Retina late 2013) wake from sleep?

I have 2 x USB hubs, a Logitech USB 2.0 hub and a Broway USB 3.0 hub. Tested both and both seem to be the cause of my late 2013 Mac Book Pro waking from sleep. I ran syslog to find out why (syslog |grep -i "Wake reason") and the reason I got back was "kernel[0] <Notice>: Wake reason: XHC1" - this means nothing to me, but it didn't take too much mucking about to hunt the problem down and figure out it was the USB hub with any USB drive attached. If the drive is attached directly to the computer. No problem, computer sleeps fine.
This was a problem I encountered (and never solved) with OSX 10.6.8, a 2008 Macbook Pro the same Logitech USB 2.0 hub, but with different drives. I put the problem down to a bug that never got solved in an old system. But I am simply AMAZED after my update to a new MBP and new system that it is still about almost 6 years, a dozen MBP's and 4 systems later.
The other problem is that not only does the USB drive/ USB hub combo wake the computer it also loses the drive upon sleep and mounts it again upon wake. Then repeats this process every couple of minutes. And it obviously doesn't eject the drives properly because each time I return to the computer after I put it to sleep or let it go to sleep I get a giant list of "Disk Not Ejected Properly" notifications about it. Which I'm guessing could eventually cause some file damage.
I've tried combinations of different drives, different hubs (a Belkin and a no-name Chinese brand 2.0 hub) and the problem persists. Is there a solve to this problem? I'm surprised to see so little posts on forums about this. Am I just unlucky and got another combination of faulty/problematic hardware, or is this a real problem that exists for everyone? If not I would love to know if people have found winning combos of USB hubs and drives. But if it is, then it HAS to be solved.
If you have a Macbook Pro, then you are limited to 2 USB outlets, this is obviously a bare minimum and I would say that 95% of people using their laptop computer in the office or at home have a hub, and very likely a USB drive attached to it. I know actual Apple reps don't really pay much attention to the community support posts, but I've got 6 months worth of Applecare left and would like suggestions about how to get Apple's attention about this problem.
BTW Jettison (a 3rd party app that ejects drives properly before sleep) is not a solve. It is a 3rd party app that tries to fill a hole in a broken system. I don't want to eject my drive upon sleep, I want it to got the **** to sleep.

Is there a pattern to the time of day or other detail that may be
traced back to a OS X system cause of this odd phenomenon?
Are there any copies of system files on any of the attached USB
external drives? Any libraries, such as iTunes, iPhoto, etc?
Once the drives are indexed by Spotlight, are their permissions
ignored by the OS X? Content, if neutral, should not affect the
wake or sleep cycle; especially if they're ignored by the OS X.
Could there be a bad cable or other component? If so that would
be a difficult process of elimination to detect it. Usually replacing
most suspect components in the USB stream (external to Macs)
is a rote way to mechanically test that idea; & not 100% sure.
Does the equipment all have a good ground to the utility or house
electrical field? An intermittent ground may affect more than sleep.
Hard to say at this point. Maybe a late-night talk radio guru on
remote viewing could peer into your situation and sleuth it out?
Sorry to have run out of ideas, but the process must be electrical
& mechanical to some extent. - Or perhaps odd software inspired.
Do you have any phone-home spyware items inside, just jumping
at the chance to spill your information? Little Snitch may help.
PS: Perhaps the computer needs to go into Apple & have a genius
or product specialist at AASP test the unit thoroughly... BlueTooth?

USB Device Not Recognized - USB device attached has malfunctioned & Windows does not recognize it

I have an HP Pavilion dv4 Notebook running Windows 7 Home Premium and the USB ports worked fine for an HP deskjet printer and an older Casio digital camera. Then one day, the laptop decided not to recognize the Casio digital camera and gave the error message "USB Device Not Recognized" and also indicated that the device attached to the computer has malfunctioned. This prompted me to buy a new Canon digital camera. Well, a new camera did not fix the problem. Now, anything connected to either of the 2 USB ports will not be recognized by my laptop. Help! I'm at a loss to figure this out. I've tried the suggested Microsoft help below:
Suggestion 1: For the issue with USB devices, uninstall and re-install all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition.
The USB controllers represent the USB ports in Device Manager.
a. Click Start, type device manager in the Start search box and hit Enter.
b. Expand Universal Serial Bus controllers.
Note: You might have to scroll down the list to find this item.
c. Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
d. Repeat the above step for each USB controller that is listed under Universal Serial Bus controllers.
e. Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
f. Check the USB device to see whether it is working.
This did not correct the problem. Then from device manager, I tried updating drivers on all the USB controllers and root hubs. While some may have received downloaded software updates, it still did not correct the USB device not recognized problem after restarting the computer. I'm hoping someone knows of the fix to this situation and can pass it along to me. Thanks for reading and posting any help.

Hey 655micha,
I'm sorry you're having an issue with a USB device. Do you get an error window that pops up? If so what does it say? Have you checked Device Manager? Is is just one device that isn't working? Has it ever worked before? Is it just one USB port in particular that isn't recognizing devices?
What model do you have? Here are the steps to find your product number. FN + ESC is the easiest way to find that information.

HT202731 Unstable operation when 2 or more USB devices connected to usb port on a MacBook Pro running Yosemite

I have tried connecting a number of devices to my MacBook Pro but I have found if I try to connect 2 or more using either usb ports or a usb hub the computer reports 'disk not ejected properly' and sometimes it will fail to recognise the device and remove it from the desktop or it stalls operation and I have to turn the computer off at the power button.
I have tried erasing the hard drive and reinstalling the operating system.
I have done various types of reset suggested by apple support.
The computer has been to an Apple dealer who has tested the hardware but found nothing due to the intermittent nature of the problem.
I have operated the computer with only the software originally installed on it present.
Could it be possible that a virus could be present on the usb devices I am trying to connect?
My computer is a MacBook Pro (13-inch, Mid 2012)
Processor 2.5 GHz Intel Core i5
Memory 4 GB 1600 MHz DDR3
Startup Disk Macintosh HD
Graphics Intel HD Graphics 4000 1024 MB
Operating System X Yosemite 10.10.1
Devices I have connected to USB ports all USB 3.0 compatible in a variety of combinations:-
7 port superspeed USB 3.0 hub (powered).
4 port Inateck USB 3.0 portable hub (not powered).
Buffalo ultra portable 500Gb USB 3.0 hard drive.
Seagate Expansion portable 500Gb USB 3.0 hard drive.
Seagate Expansion desktop 2Tb USB 3.0 hard drive (powered).
Seagate Expansion desktop 3Tb USB 3.0 hard drive (powered).
ScanDisk Cruiser Edge 16Gb USB stick.
ScanDisk Cruiser Edge 32Gb USB stick.
Hewlett Packard 16Gb USB stick. (This causes an instant crash now.)

Why?
- Because when I'm editing/ rendering lots of HD video everyday, I don't want to share system resources between virtual machines... I want the entire system's resources devoted to what I'm doing.
- I don't want to spend anymore money than I have to in order to buy one of the faster virtual systems. Not to mention, I've had a bad experience with Parralels in the past and I'd rather not use one again.
- I really don't want to clutter up my system anymore than I have to for a project that's only going to take a few weeks.
- I don't mind swapping hard drives... it takes two minutes, and I have an empty ssd just sitting on the shelf.
So, back to my original question. Can I just swap the computer's drives, then install Ubuntu on the second drive and be good to go without any harm to my MacBook Pro or OSX on the other drive (which wouldn't be connected when Ubuntu is running)?
Thanks.

Usb 2.0 to usb 2.0 drive transfer rates

hi everyone. this may be obvious but i wanted to ask anyway. one of my external HD's drives died (well, the electronics died, the drives were fine). luckily i had everything backed up on a USB 2.0 OWC USB drive. i bought a new interface to plug the drives into from the dead drive which is also USB 2.0. so i'm trying to transfer the info back from the backup drive to the original drive, but its painfully slow, like 1GB an hour. is this because i'm transferring from usb 2 to usb 2, or is it possible the drive is damaged? the old interface was FW800/400/USB2, and i remember it was slower than i thought it should be to. i don't have the drive specs with me right now, but i do remember it was a 500GB fantom drive.
hope i haven't lost you here.
any info is greatly appreciated, i'd just like to figure out why its so slow.
thanks!

Hi jhw1,
That doesn't sound right, at all. I did a quick check of my hardware and got the following:
Test #1: A single 2GB file (.dmg)
Test #2: Ten files totaling approximately ~2GB (.dmg)
Test #1: 2 mins, 24 seconds
Test #2: 2 mins, 19 seconds
I tried it again and got pretty much the same result. In writing a single 2GB file from the internal HD to both external HDs at different times the transfer took about 1 min, 40 seconds. The drives I used were an Iomega 320GB drive and a LaCie 250GB drive and they were connected to my MacBook Pro's USB ports.

iMac 20" Mac OS X (10.4.8)

Personally, I would not launch into a rant against Nokia about this as you have now done unless you have some evidence that it is actually their fault.
I have only seen this problem with recent Nokia phones reported by just a couple of people and I have seen no evidence that it is strictly Nokia's fault - it may be so or it may not be. It does not seem to be widespread.
If you do a Google search for "Error 633 Modem in use" you will see that the problem is encountered, seemingly randomly, by some users with a wide variety if devices not just phones as modems but other modems as well and all from a wide variety of manufacturers, not just Nokia.
If you read through the thousands of Google links on the error 633 problem you will also see that there seems to be no well defined solution to it - seems to be encountered by small proportion of users of a device but not all so it would seem that there are usually local machine issues involved.
In the end, as I set out, if it is important to you that you have the modem working I have found that for me with an N8 (Anna) it all works fine with Win XP installed in a virtual machine on the Win 7 64 PC.

From usb 1.1 to usb 2

With the new iPods video and nano using only usb 2, I'm wondering: can I upgrade my usb 1.1 to usb 2 on my PB 12in. Not that I'm looking to do it myself, I just want to know if it's feasable.

Get as big a capacity as you can afford, SMS1.
Looks like a nice little drive. You might want to have a look at the LaCie portable drives too, if that is what you are after. Of course, if you don't really need it to be "bus powered" you can get a much larger drive that runs off mains power for the same sort of money (I rapidly found that an 80 gig drive was only just large enough for backup and other purposes with my own PB 12 with a 40 gig drive).
If you go for a larger, powered, drive LaCie's D2 series, Maxtor's "One Touch" and the Seagate externals are all good, and are offered with Firewire. If buying in the US for use in China , though you will need to make sure that they are compatible with Chinese voltage.

I have read on some sites that not all USB adapters work properly.
You should firstly google around for more informations about such adapters.
If you are sure that it will work so you can buy it.
Anyway, the PCMCIA is a good solution

Is there USB 1.1 to USB 2.0 Upgrading Software-Patch?

Hello,
I wanted to buy External-DVD-Writer with USB connection,
all the models are *USB 2.0* specific,
my imac has *USB 1.1* on the computer and the keyboard,
sales person told me that there is *USB 2.0 UPGRADE* that i can download
and upgrade my *USB 1.1* to *USB 2.0*.
Is there such a download?
Thank you.

Hello,
It would be far better to purchase a Firewire External Drive. You cannot boot a PowerPC (G4) iMac from a USB drive and Firewire is faster for sustained transfers than USB2.0.

I would suggest that you shop elsewhere in future; this sales person clearly doesn't understand what they are trying to discuss(!).

Is there an easier way to transfer your iTunes library on windows to a mac than copying the library to a usb and plugging the usb into the mac and put the library in the iTunes file

is there an easier way to transfer your iTunes library on windows to a mac than copying the library to a usb and plugging the usb into the mac and put the library in the iTunes file? I recently swapped to Mac and this is how i moved the library from windows to mac and library is in tact but is there an easier way? My cousin just imported her cd's again, but it was harder for me as i have an ipod with over 150 apps and i needed to move them. i think it would be helpful if i knew of an easier way so i can help a friend move his. Thanks

The general method of use is to download a script (double-click or right-click and use Download or Save As...) to a folder of your choice, e.g. your Desktop, Downloads folder or create a folder at ...\iTunes\Scripts. Select a playlist or highlight some tracks in iTunes and then double-click on the script to execute it. If no specific tracks are selected the script will try to work with all tracks in the current playlist or sometimes the entire library.

Anker Powered USB Hub (7 port, usb 3.0) often won't light up (function) after waking Mavericks from sleep

My iMac is 27" (mid-2010) with 8 GB RAM. My only problem is that my new Anker Powered USB Hub (7 port, USB 3.0) often does not wake when computer does. In other words, the power lights remain off following waking the computer from sleep and I must unplug and replug the HUB. I called Anker and they told me that Mavericks has a new "energy saving power mode" that may turn off power to a USB hub. This is most annoying and I hope that Apple can update Mavericks power management to fix this USB issue. Has anyone else experienced this problem? I've seen similar posts from D-Link USB hub owners. Perhaps if this "question" has a response trail, Apple will see it and create a fix.

Hopefully, Apple will monitor this issue and correct the USB power management issue. We'll see what happens with Yosemite.
