High-Powered USB vs Non High-powered USB ?

I have a new shuffle(512 mb). I have successfully loaded the itunes software on my 2 year old Dell PC. I have 2 USB ports(500 ma) on the back of the tower.
I have plugged the ipod into a USB and itunes has recognized it. I have successfully uploaded several playlists.
I have however received window messages that a high-power device is plugged into a non high-power USB port. I plugged my ipod in for charging and the status light is amber. How do I know if the ipod is being charged by this non high-power USB port?

Hi,
From your description it is very clear that the USB ports in your computer is a low powered USB 1.1 port, to charge the battery of an iPod shuffle it should be connected to a USB 2.0 port.
You may plug in the iPod shuffle to any computer which has a High powered USB port for a maximum of 4 hours for a good charge. Right now the iPod shuffle is in low charge.
Otherwise you may buy an USB power adaptor from Apple Store.

"This High-Speed USB device is connected a non High-Speed USB Hub" pops up!

Hi. I have an iPod mini and a Window XP desktop. I've checked my computer as stated in the forum. I know I have a USB 2.0 port according to one of the posts I've read, but I guess it's not a high speed LOL. So I was wondering if it takes more time to fully recharge the iPod mini with a non High-Speed USB Hub than it does with the High-Speed USB Hub.

USB 2.0 high speed card won't run Canon MP800 printer

I have a Power Mac G4 AGP graphics. I installed OS X 10.4.4 on it. I purchased a new Canon PIXMA MP800 multi-function- printer. It needed a USB 2.0 high-speed connection. I purchased an Allegro USB 2.0 high-speed adapter card and installed it in my empty PCI slot. Here's my problem: When I connected the Canon printer, it would not print or scan.....it just went through the motion of sending, but not completing the task. I called Canon to trouble shoot the problem. I connected the Canon printer to my native USB 1.1 port and it worked fine. I then, removed my PCI card and reinstalled it, to be sure that it was seated correctly in. The Canon still would not work. So I plugged my old HP 1200C printer(USB 1.1) into the USB 2.0 port and my printer did work, but at the USB 1.1 speed. I contacted Sonnet Technology on the Allegro USB 2.0 PCI card and they said to try a utility called Cocktail or Tiger Cleaner to try and fix the problem. I downloaded Coctail and ran it to see if this would work. It didn't fix my problem. Any suggestions?

what type of USB 2.0 PCI card did you put in? have a look at the card and find out what chip is on it and let me know. I put one in mine that has the VIA VT6212L chip in it and it doesn't work either, despite OS X having native drivers for USB 2.0 cards.
The USB ports on my card didn't work at all until I installed a driver that I got from VIA. Even then though only 1.1 devices work while the 2.0 devices are not even recognised.
From what I hear, adaptec brand USB 2.0 PCI cards are what you want to get in future, plug them in and off they go (wish I'd done my homework). No messing around with drivers that support only half your new hardwares features.......of course its the other half that you actually need.
I've spent hours reading through all sorts of info and scanning forums everywhere to try to find a fix, I understand why you're a little woozie. A possible fix that people seem to keep suggesting is to zap your PRAM (restart holding command-option-P-R keys, don't release the keys until after the 3rd chime), didn't help me and I doubt it'll help you but at least when people tell you to try it you can say you've done it.
here's my post to my problem:

Which iMac usb port is high power?

Which iMac USB port is high power?

I'm not sure this is the case, at least on the newer iMacs. Some ports will adequately power some devices (most notable the USB Suerdrive) while others won't. Or, this has been the case recently, anyway; USB with Apple devices seems hopelessly arcane anyway, which makes no sense at all!)

Thinkpad W530: None of the USB ports work when used with a 4338-35U replicator

I have tried mouse. keyboard and a generic USB stick with a LED. None of the USB ports work on the replicator. Everything works fine when connected directly to the W530. The replicator ports must not have power because the LED doesn't come on.

Hi mmjmm123,
How long have you had your replicator?
Has it always been like this?

None of my usb flash drives are mounting

OS X 10.6.8 - None of my usb flash drives are mounting. They don't show up in disk utility either. System proflier does show the flash drives. I've run disk warrior and the flash drives show there as well. I've tried all of the usb outlets with several flash drives and none of them show up. I can use the same usb outlets to use my wireless keyboard, mouse and also my ipad.
Finders preferences are all checked to show items on desktop.
One of my flash drives I tried several times and finally got this screen message. "System extension cannot be used The system extension "/System/Library/Extension/IOStorageFamily.Kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update. Non of my other 6 flash drives mount and they do not receive any screen message.
I've also run repair disk permissions several times and the it says permissions repaired so I run it again and the same issued it said it was repaired, it lists again. I've done this several times with the same results.

Hello
from that
"System extension cannot be used The system extension "/System/Library/Extension/IOStorageFamily.Kext" was installed improperly and cannot be used"
try this
- boot from your original system disc
- plug one of your usb flash drives
- see if installer software could use usb flash drives as target for install
( testing your usb flash drive from a know good system software )
- DO not perform install on flash drive , just need to know if flash is usable
if it could , re-install your system or if it was updated from a previous version re-install 10.6.8 combo update

checking for any missing update ?

USB 1.1 but no USB 2.0 on MS-7125 [solved]

I have Gentoo AMD64 2005.0 with kernel 2.6.11-gentoo-r11 running on an MSI K8N Neo4 nForce 4 Ultra Platinum motherboard (MS-7125). I tried two different USB memory sticks. The first is recognized by the kernel with no problems. dmesg reports the following.

The BIOS has two settings for USB which allow only enable/disable and both are enabled. Also, a thread in this forum indicated that connections to pin 10, USBOC, might cause problems but I have nothing connected to that pin.
Has anyone got USB 2.0 working under Windows XP on this motherboard, MS-7125?
Edit: USB 2.0 (the ehci_hcd module in Linux) now works flawlessly using the newest kernel, 2.6.12-gentoo. In Linux, at least, good things happen to those who wait.
Edit2: USB 2.0 malfunctioned in later kernels while it worked under XP x64. I believe it depends on the kernel and maybe udev. Under my latest kernel, gentoo-2.6.14, and udev 071 USB 2.0 is restored.

maybe use a different OS or put this in the "operating system" section and see if they can help?

It is possible to charge an iPad3 over USB and transmit data over USB at the same time?

Hello,
it is possible to charge an iPad3 over USB and transmit data over USB at the same time?
If yes, how?
Thanks
Best regards

OK!?
That is right that the USB data oins are not connected to +5V pin.
But i found a description for a self built power supply for iPad.
http://timothyb.net/DIY_iPad_2_USB_Charger.html
and
https://www.mikrocontroller.net/topic/262610?goto=2726627#2726627
The description say: data pin D- need a voltage level of 2V and D+ 2,857V
when the data pins have this special voltage levels and VCC has +5V only then the iPad is charging.
The voltage "D+/D- coding" is the key for the iPad to charge.
OK now back to my problem.
The regular USB data pin voltage level is 0,3 - 3.,0 voltage. When the iPad is charging the data pins have this special voltage level. Now i try to transmit data over the usb data pins with the. Normaly the USB port transmit the data with a voltage level of max. 3V.
And here my problem. The higher voltage level at the data pins cares therefor that the iPad stop the charging.
Is that correct?

Can't copy large files to an USB Disk pugged in an USB hub

When I tried to copy large files to my USB disk pugged in an USB hub, it stopped at 220 Kb... When I plug the disk to the internal back USB port it works fine ¿Any idea?
Thanks

Hi, cguzman -
Related to what Templeton suggested, if your USB hub does not have external power (self-power), try replacing it with one that does.
If your hub is self-powered, many of those have a small selector switch on the side or rear which allow the choice of self- or bus-power. If yours has such a switch, make sure it is not set to 'bus'.

Can I use a USB hub to connect to multiple USB ports from one GPIB-USB-HS?

I have one instrument which has a GPIB-USB-HS connected and the USB cable is connected to a USB hub. Can I have multiple PCs to connect using USB hub at their respective USB ports? If so, how many PCs can I connect using the USB cable?
I have downloaded the latest NI-VISA from the website.
Solved!
Go to Solution.

You would first need a hub that allows you to switch between multiple pc's and then only one pc at a time would be connected and in control.
When you buy this special type of hub, one of the specs is how many pc connections it has.

I'm new to apple after years of MS OS! How do I transfer files from my USB memory stick to another USB memory stick? cheers

hi all, i've just switched to apple after many years using MS OS! I'm now using iMac desktop 21.5" with 2.9GHz processor and latest Yosemite software.
How do I transfer files from one USB memory stick to another USB memory stick on the iMac? cheers, linley94

Plug in the memory stick and it should open then create a New Folder and drag and drop the contents from the memory stick to the new folder you created. Remove the original memory stick all the information should be in the new folder you created. Now plug in the new memory stick with nothing on it when it opens drag the folder with the contents from the original memory stick folder and all into the new memory stick that opened and there you have it.

When it was originally released it only worked with the MacBook Air which came with a special version of OS X that supported this adapter. Apple seem to have since built this support in to versions of OS X 10.6 and later for all Macs.
If you have an older version of OS X e.g. 10.3 to 10.5 then an unofficially driver is available here http://www.sustworks.com/sb_site/downloads.html

IP4 Charging..USB to PC (MAC) vs USB Wall Charger??

Could there be a difference in the way the battery is recharged when charging the IP4 using a USB cable connected to a USB dock, which is connected to a Mac Mini vs charging the phone using the USB wall charger?
Couple days ago my IP4 battery drained normally, indicator went red since it was less that 20% capacity, so I plugged it into a USB cable that I had been using to charge my IP 3G. That cable goes to a USB dock connected to my Mini, my 3G always seemed to charge fine using same calbe...seems the IP4 charged ok as well...though it did seem to take longer for a full charge. I briefly used the phone that evening. When I went to bed, battery was at about 90% charged, almost full charge. Next morning, it was down below 20%. Charged it again next day using USB wall charger, used the phone more last night, but phone was close to 90% available this morning.
I don't believe the previous evening I ran any wacky app or process that could have been running overnight, I checked that first, same few apps I normally used showed.
So, does how the IP4 get charged, USB to PC vs USB to wall outlet make a difference in how the battery charges?

it will take longer to charge on a computer because there is less power going to the phone thats just the way it works
however no matter where you charge it and how long it takes to charge its not going to deplete quicker based on one source or another there must have been something that drained your battery
