USB port for iPhone

My computer's USB port is only 1.1 and the iPhone requires a 2.0 port. Is there an adapter available to convert my USB to 2.0? Or do I have to buy a new computer as well as an iPhone? Any suggestions?

Question: If Hi-Speed USB 2.0 is a 480 Mbps interface and FireWire is a 400 Mbps interface, how can FireWire be faster?
Answer: Differences in the architecture of the two interfaces have a huge impact on the sustained throughput.
* FireWire, uses a "Peer-to-Peer" architecture in which the peripherals are intelligent and can negotiate bus conflicts to determine which device can best control a data transfer
* Hi-Speed USB 2.0 uses a "Master-Slave" architecture in which the computer handles all arbitration functions and dictates data flow to, from and between the attached peripherals (adding additional system overhead and resulting in slower data flow control)
* Read and write tests to the same IDE hard drive connected using FireWire and then Hi-Speed USB 2.0 show:
*Read Test:*
5000 files _(300 MB total)_ *FireWire was 33% faster than USB 2.0*
160 files _(650MB total)_ *FireWire was 70% faster than USB 2.0*
*Write Test:*
5000 files _(300 MB total)_ *FireWire was 16% faster than USB 2.0*
160 files _(650MB total)_ *FireWire was 48% faster than USB 2.0*

Splitting the Time Capsule USB port for 2 devices ??

So if i have and external HD plugged into tc usb port and I also need to plug in a netflix ready blue ray player to the same port- is there a splitter I can buy to do this or what other options do i have?
I have an extra airport extreme I am not using-could I run an ethernet cord to it and use that usb port for my second device without and problems?
Thx

First, yes it is possible to attach multiple devices to the TC's USB port. You will need a USB hub though. Some users have discovered that not all hubs are compatible with the TCs USB port. So you may need to shop around if the first one doesn't work.
However, the USB port on the TC is designed primarily to handle external HDs or printers. That is, it is designed to make them available to your local network, not to the internet. So I have doubts that the BR player will be able to have full interest access via the TCs USB port.

im not shure but if you get an 3.5 mm sterio headphone jack and plug that in your car and shuffle it should work just as good

If all your ports are in use, try buying a USB hub, they are inexpensive and will give you several more ports. Google for them.

Which USB port for extra power for external Superdrive?

I just bought an external USB slimline optical drive that doesn't use AC power, instead it comes with a USB Y-connector so that it can use two USB ports for power. I can't really spare the extra port. I read that the Mac mini 2011 is compatible with the Apple USB Superdrive. It does this by supplying additional power over USB, like the MacBook Air. I've tried my drive with just a single port and it powers on and can do some stuff, but suddenly it'll crap out and the OS will tell me the disk was removed without being ejected. I've determined it's a power issue. Does anyone know which port in particular the extra power is delivered through? I'd test myself, but I'm afraid I may be damaging the optical drive when it craps out.
Thanks

I'd get a good AC high powered USB Hub...

Macbook Air - USB port and iPhone 4 Madness

Hi there, I have a brand new 2013 macbook air, love the weight and speed - but - I'm running still 10.8.5 and have the iphone 4,
plug into the usb ports and the iphone goes crazy with on / off charging and buzzing, i repeat that a few times and it calms down
has anyone had issues with older iphone 4 and the usb ports on the latest Macbook Air? I have the news itunes now installed also,
but no help
thanks, its truly freaky, going to sit it out until 10.9.1 is out, as my girlfriends Macbook Air has now Mavericks and its acting up on the Mail app,
had to recreate all the accounts from scratch to avoid 100% cpu useage and battery drain, so avoid Mavericks for a bit

Hello null.
I have OS Mavricks installed on my MBA 2013 and I have the same issue with my iPhone 4s. I noticed that when my iPhone is charged about 60% or 61% and above it connects normally without any issues, so the solution at the mean time is to charge it to that percentage and above and then connect it, Weird!

Using USB port for dial up networking with mobile phone?

I am thinking of using my mobile phone as a dial up modem when i am away from home and it uses a data cable to the USB port. is there a way to use the USB port on a Mac as your source for the internet?
Thanks
Jason

well i dont have the cable yet i just was wondering if that would work. Yes it has bluetooth but i was told you cant use the bluetooth for a modem. Dont know why the phone has the option. How would i set up that option?

Can't use front USB port for external Hard Drive

I have had some problems for about the past year with the front USB port on my 2009 13in Macbook Pro 5.5.
As you know, there are 2 USB ports on the left side on a 13inch Macbook pro. The one closest to me (the front one) works fine when I use it with a flash drive. But when I connect my external 7200RPM external drive to it, after about a minute, it ejects then re-recognizes the disk.
I video edit with FCP and use the external as one of my scratch disks.
At first I thought maybe it was the cord or the drive that was messed up. But then I connected my other external drive to this port and the same thing happened.
But when I connected it to the back USB port, everything works fine. I haven't had any trouble. So i make sure it's connected to that port when using the external.
Why would this be happening. It only screws up when using a standard external drive but not flash drives or any other peripherals.
Thanks
Brandon

Exactly what Ogelthorpe mentioned.
I bought a Seagate 500GB 7200RPM and bought an external case from Staples that has a big fancy led to show HD activity. Sometimes it works and sometimes it doesn't.
Tested it on my PC and it works all the time so it got me stumped. Thought it was my MB.
Decided to try another external drive drive on my MB and everything works. So I returned the fancy external enclosure and bought the simple $10 one.
Now everything works fine.
Maybe changing your external case might help you.

Using the USB port for an external HD dumb question

OK. Forgive a possibly really dumb question here...
My external HD has a USB 2.0 interface and I hooked it up to the USB port using a cable that came with an old USB 1 hub I'm not using right now.
My dumb question is this: is there such a thing as a USB 2.0 cable? Or are the USB cables all the same?
Also, how long should it be taking to transfer 12.1 GB of data (about 9,000 photos) from my external HD mounted on the AirMac base station to my MBP? There are still 48 minutes left and it seems an awfully long time for 12.1 GB of data. That's why I was wondering if the cable could be an issue...
Thanks,
doug

I am suspecting now that my HD might really have been a USB 1.0 drive...

Distortion using USB port for audio output

I did some research in the Mac Mini community regarding the problem I'm experiencing but most of the posts were several years old so I thought I would start a new thread.
I am using one of the USB ports on my 2011 Mac Mini (2.3GHz, i5) to feed a High Resolution Technologies Streamer II USB DAC which then connects to my audio systems integrated amplifier. The issue I'm experiencing is that I am getting distortion when I first open iTunes and start a music track playing. I can hear the music but it is overlayed with this static like distortion. It seems to happen specifically when I first wake the computer from sleep and open iTunes and try to play a track. If I close and reopen iTunes and start a track playing again the distorion usually goes away and all tracks after the initial distortion play fine. I've done troubleshooting with regards to the HRT USB DAC and made sure the Streamer II is operating on its own USB Bus and I've tried a powered USB Hub to feed only the Streamer II but the distortion continues. So aside from the obvious hardware malfunction possibilities I was wondering if anyone else has experienced this problem. Thank you,

well i dont have the cable yet i just was wondering if that would work. Yes it has bluetooth but i was told you cant use the bluetooth for a modem. Dont know why the phone has the option. How would i set up that option?

Motorola Hz800 Bluetooth headset shorts out MBA Bluetooth Module when plugged into MBA USB port for charging

This is the weiredest thing. Everything is fine with my MBA, I have an apple bluetooth keyboard and mouse running smoothy then I plug in my Motorola HZ800 bluetooth headset using a USB to mico USB cable to my MBA to charge it and BAM! I get a the bluetooth logo with a sawtooth wave through it. It shuts down the bluetooth module completely. I have to restart the computer to bring back the bluetooth module to life. And now my keyboard won't pair again, but that's a whole other issue. Any reason why this would be? Thanks.

Yes. USB ports are limited to a maximum of 500 ma of current. Check the current rating on the charger for your headset. It is probably higher than 500 ma. It overloads the port forcing it to shut down.

USB Port for iPod Not Found

The problem seems to be that the USB port is not being recognized by the software. I tried using Anapod and when I launched the program it could not find the iPod device even though it was connected in the USP port on my laptop.
BTW - I tried all four USB ports and the results were the same
Any ideas how to fix this?

I'm having the exact same problem. I've reinstalled all the iTunes software several times. I have an iPod mini and an iPod nano that will not show themselves in iTunes. However, if I take them to my laptop, they connect perfectly with iTunes. Is there some way to rid myself of the usb drivers for iPod so I can get it to try to recognize the iPods?

So what is the USB port for anyways?

I hear that we can not use the USB2 port with Hard drive, so what is it for?

The USB port is intended for internal Apple usage, such as troubleshooting; it is not usable by customers except through hacks.

Cannot get my iMac chooser to acknowledge the USB port for Epson SP 700

I have an old iMac (that looks like a big blue bubble) with OS 9.2. I have an Epson Stylus Photo 700 that I’ve had since 1998.
I have a set of 9 year old triplets that I want to set the two up together! I’m thinking Good Luck…because I have tried everything. I downloaded the Epson drivers, bought a USB/Parallel adapter (as the Epson has no USB port.) The apple acknowledges the SP 700 under the chooser, but there is NOTHING on the right of the chooser to acknowledge the Epson in the USB port. Do you have any suggestions? I have a feeling there is some adapter card that is not on my OS 9.2 that needs to be downloaded. I saw something on the site 1.4.1, but I am scared to download that as under the apple system for the printer it says “O” next to the USB port , but it says 1.5.5, so I figure it is not smart to download any #’s less than that (like 1.4.1). Do you know of any adapter card that would work? Or some download I don’t know about, or is there one? Or can this even work or am I out of luck! I would be greatly appreciative of anything anyone could suggest.
iMac Mac OS 9.2.x

Hi pbk333 and welcome to the discussions.
THose early Epson USB drivers could be pretty pernickety, and even more so when used with a serial to USB adaptor. I see HERE, that there are a couple of "Driver updaters" available for use with the iMac etc. It may be worth trying them. THere is also some relevant information on the Epson site at http://www.epson.com.sg/other/help/inkjetcommonfaq.shtml
But a couple of other points. Firstly you've posted in the iMac G5 forum (which is mainly inhabited by people using the much newer "flat screen" iMacs that run much later operatings systems than 9.2. You are more likely to find someone who knows about this probem (or at least can remember whether there was a simple answer!) in either the iMac G3 forum at http://discussions.apple.com/forum.jspa?forumID=888 or in the OS9 forum at http://discussions.apple.com/forum.jspa?forumID=669
Secondly, those old printers can be pretty expensive to run , especially where children and colored ink are concerned! You may find that you can get a much newer printer, with cheaper ink and less problems with set-up, for not much more (maybe even less!) than a set of inkcartridges for the old Epson. I know OS9 compatible printers are getting hard to find, but something a little later than your Epson 700 (even a second hand Canon i560 or similar) might be a lot less trouble, and cheaper in teh long run, especially if children are using it.
Cheers
Rod
