USB bus powering is no longer available?

Hi,
Previous to updating to 10.4.3, I was easily able to bus power my midi controller (a Korg MicroKontrol). I recall after updating to 10.4.3, the controller would no longer get powered, and I had to resort to powering it by battery instead! Did other people experience this also? Does 10.4.4 solve this problem? Really annoying.
Thanks;
John
Powerbook G4 15"   Mac OS X (10.4.3)  

No idea but try 10.4.5 and see if it works better.
Also the more power you take by USB /FIREWIRE leaves less for the underpowered cpu as is.
If the cpu is 1.5 it should have at least 1.25v for max performance.
If it is 1.67 it should have 1-50% or 1.38V or 1.4v to be safe.
Unfortunately it is not a viable option for Apple to get this up as it is cheaper to build it like this or build a complete new one that fixes bugs etc. in the hardare.
To see how much juice it uses get HARDWARE MONITOR as it can show fan speed temps. Voltages used ect. depending on the sensors in your MAC. (GERMAN program in English)

  • USB Bus powered externals?

    Hello,
    I have a PowerBook G4 hi-res.. Has anyone had any success in hooking up an external bus powered USB/Firewire based external drive without under power issues? I was told that even the Macbook and Macbook Pros still suffer from under powered USB ports, but surely since the PowerBook I have has 2 USB 2.0 high powered ports, surely this is the same as on the macbook and macbook pros?
    Which hard drives through firewire/USB bus power work well with the PowerBooks which have 2.0 USB ports? Now that I can boot off a USB on my PowerBook G4 with ease, I wanted to take advantage of such a drive as I am in the process of determining if its better to not replace the internal hard drive which is only 100GB and to just get a 1TB or 500GB external hard drive(internal enclosure would be SATA-II).
    Thanks.
    And no, I am aware that the PowerBook won't take SATA, but since the sata drive would be in the external enclosure, the only thing hooking up to the powerbook would be USB or firewire.

    Look, I am not dismissing firewire at all... I just like the option of USB and using that OF boot code it does indeed work.. Its good that both options are available.. using the Y-cable adapter for both USB ports is fine... for my purposes.. but I am well aware that firewire is the way to go for ALL macs, INTEL AND PowerPC..
    But sometimes you need another option in rare circumstances.. Plus, a friend of mine has a PowerPC mac and I am showing him next week that USB can indeed be bootable, provided one types in: boot ud:3,\\:tbxi or boot ud,\\:tbxi(if this is the only external device).
    Sorry to ramble on about this.. I am just defending the proof that PowerPC macs can indeed boot from USB 2.0 drives.. whether PPC G4,G5 - I haven't tested it on a G3 though.

  • Bus powered external drive for MacBook

    Hi,
    I'm looking for an external HD to use with my MacBook, and I'm a bit confused about power. I'd rather avoid lugging around an extra power supply and international adaptor when I'm traveling if it can be avoided.
    Does the MacBook's firewire port provide bus power? Is it sufficient to power a 2.5" external HD?
    Is USB a better option if I want a bus powered HD? Are there any clear advantages to one or the other?

    For the longest time, FireWire was the only practical solution to bus-powered hard drives. FireWire provides a heck of a lot of power (typically 7 to 8W) while USB by definition provides up to 2.5W per port (if powered). FireWire has so many advantages, but cost seems to be the consideration that's won out.
    Current USB bus-powered external drives seem to be feasible because of newer 2.5" drives with reduced power consumption. Still - many drives come with (or they can be bought) cables with two male ends. One end is used for data/power, while the other draws more power from a 2nd powered USB port.
    I have no problem getting a 160 GB WD Passport (Black) USB 2.0 drive to work on my iBook 1.42 or my new MacBook. It does take a while to mount in the OS though, although the same goes for Windows.

  • Early 2011 17" MBP -- USB 3.0 portable, reliable, bus-powered option?

    Hi everyone,
    I have the above mentioned MacBook Pro, and have been scouring the Internet for quite a while trying to find a solid USB 3.0 solution.
    Ideally what I'm looking for is accesibility for portable, bus powered USB 3.0, 7200 RPM hard drives.
    I know there are limitations in what expresscard/34 can deliver in power, and have been really trying to figure out solutions, as my drive isn't getting sufficient power from my current card, especially if both usb 3.0 ports are occupied (even if the other is just a camera SD card, the HDD will just 'click').
    I've looked at different adapters, and Sonnet seems to make a pretty decent one that has two ports, and can be powered by a wall adapter is purchased from a third-party like OWC. This, however, would still leave me in a situation where I would always be reliant upon electricity, detracting a lot from the portability factor. It is also limited to pretty much only storage devices, and doesn't support USB 3.0 hubs
    CalDigit makes an adapter as well that seems to be well received, but it cannot be externally powered from what I can tell… so I assume it would not provide enough power to the drives?
    One option I have thought of is to get a USB 3.0 y-adapter, and plug the extra "power" USB plug into the adjacent USB 2.0 port.
    Would this work, and likely provide enough power?  Or would the speed be throttled down to 2.0 speeds?
    Another option seems to be the CalDigit Thunderbolt hub, which, while expensive… seems to provide a great deal of value. However, that would really limit my portability and effectively limit my USB 3.0 usage to home, or wherever I drag the box around with me to.
    Do any of these seem like they might work, or are there any other options I am not thinking of?
    It seems like the only way I will have true USB 3.0 functionality is either the CalDigit Thunderbolt hub, or parting with this particular mac (which I'd hate to do). The other thing I would possibly like to expand to is a Blackmagic Intensity module ... which come in USB 3.0 or Thunderbolt ... with the USB 3.0 a bit cheaper (and not requiring a cable...) -- I would never be able to use that with the Expresscard/34 adapters, it seems.
    I apologize for this being long, but am hoping I am giving enough information for my question to receive some feedback.
    Thank you!
    John

    As a (likely) final update to this thread, after talking to CalDigit one last time, this product is no longer being produced by them, and one of the only vendors left for it seems to be OWC.
    The card does not come with the USB "ac adapter"-type cable to add the extra needed power for bus-powered storage devices, and is not available through them, either. The CalDigit tech support rep recommended a regular USB 3.0 y-cable.
    When I inquired about driver updates, the gentleman said it will likely continue to be covered for approximately 2 more OS system updates (typically 1.5 years each, so 3 years, according to him). He said that, as I have read, that it is indeed possible that the driver is more unstable under Mavericks.
    At this point it seems there is no sure-shot solution based on expresscard/34. This is a huge pitfall, as everything else with my older macbook pro is wonderful (and upgradeable).
    Anyway, just wanted to give that final update, as it varies significantly from what I was hoping for in my last post. I suppose I could "try" it, but OWC has a 15% restocking fee, along with having to pay return shipping...both of which I confirmed I would have to pay with OWC. I am not willing to do that, as that comes out to almost $20 just to return the product if it doesn't work correctly. Shame, as I would like to give it a fair try, at least, but they don't seem to be willing to budge, and after getting burned on bad products from the past (from other sites with restocking fees), I am no longer willing to go along with those business practices.
    Good luck, everyone.

  • How many bus-powered usb external drives per hub?

    I'd like to have two bus-powered USB hard drives (to be used as backups with Time Machine) connected to one powered USB hub. Would that work, or would a powered hub be likely to support only one bus-powered external hard disk? (In that case I could get a self-powered hard drive for my second backup drive.)
    Thank you.

    Likewise it your needing another External Hard Drive, I would recommend spending a little more for a more rugged Desktop drive to use for storage or backup.
    Go with an OWC Mercury Elite Pro or a LaCie Little Big Disk and stay away from those cheap-o WD MyBooks.

  • Bus powered USB switch with a printer

    I think I know the answer to my question, but I'd like to get a few other opinions.
    Here's the question: Will the Airport Extreme supply power to a USB switch?
    Here's what I want to do: We have a Canon all-in-one printer in our office. When it's connected to the AE, we happily print wirelessly. However, when we need to scan, we have to unplug the printer from the AE and plug it into our Macbooks. Inevitably, the printer doesn't get reconnected to the AE (cough, DH), and so I get irked. To keep a blissful household, I'd like to connect the printer to a 2-port USB switch. One port will then be connected to the AE and the other port will have a dangling USB cable for use when we need to scan. My issue is that I can't seem to find a simple USB switch that also has an AC adapter. Everything I see online is bus powered and from what I can gather, the AE does not provide power to the USB port. Is this in fact true?

    Thanks DaddyPaycheck - I looked on amazon, newegg, and tiger direct with no luck, but hadn't checked OWC. Whatya know, I found exactly what I was looking for.

    I ended up buying it on Amazon for the same price with free shipping. It's good for two USB devices, even though I only need to share one printer, but the single USB switch was actually more expensive.

  • Why won't my 2011 MBP boot from bus-powered USB devices?

    In the past, I have often made use of OS X's ability to boot from an external USB device. Before installing major OS updates, or new productivity software, I usually clone my system drive onto an external USB drive using Superduper or CarbonCopyCloner. Once the clone is complete, I can then boot from the external drive (by holding Option at startup, and choosing the cloned image from the boot disk menu). This has been incedibly useful in the past when I've had hard disk problems, or when I've upgraded to a new Mac.
    My issue is with my new 2011 model 17" MBP. I am only able to boot from an external USB drive if the drive isn't bus-powered. If I try to boot from an OS X image located on a bus-powered USB flash drive or pocket hard drive, the drive seems to power down upon choosing it from the boot menu and I'm greeted by a blank gray screen. I've also tested this technique using a bus-powered DVD drive containing the Snow Leopard retail DVD (and a Windows 7 install DVD for what it's worth) and the problem remains. The optical drive will spin up upon startup, but power down as soon as I choose to boot from the DVD.
    This issue only seems to affect my 2011 MBP. I've had no issues getting the same technique to work on my old 2007 MBP or a 2008 model MacBook.
    Any help would be much appreciated.

    Fair enough.  I'll give that a try as a last resort.
    I used my wife's MacBook Pro, Target Disk Mode and a Firewire 800 cable to install Snow Leopard on my MacBook Pro as I don't have an internal optical drive any more--just the standard HD and the SSD. 
    I did use the retail disc, and I'm wondering if the issue might be that since my machine is fairly new, I might have had to use the stock install disk--which I seem to have lost.  I have the Applications DVD, but not the OS disc.
    To that end, do you know of a way to get a replacement disc?  I bought my machine at the store, I wonder if they'd be willing to copy one for me...

  • Bus powered USB drive

    I have an early 2011 MBP and would like to put a large USB drive on it that's bus powered. My recollection from earlier times was that USB drives required two ports, one for the data and one for the power. Is that still the case, or can current USB 2.0 drives carry data and power the drive on the same port?
    Thanks very much.
    All the best,
    Tom

    Tom,
    Current drives either get all their power from one usb port or if they require more current then the usb provides, they have their own power supply that plugs into the wall.

  • Bus-powered external enclosure, too many choices.

    Hi, I'm shopping for an external enclosure for my Macbook's Sata drive as I just ordered a 7200 Hitachi drive as a replacement, I would like the enclosure to be bus-powered, firewire is a good option but not necessary.
    I noticed there are a few on eBay with those characteristics, are they any good. Checked the ones on Newegg (even though they don't ship to Canada), and they are a little more expensive. There is also one that seems nice on OWC but it's pretty expensive at 80$.
    Not sure if I can trust the ones on eBay, what are you guys using/usggesting ?
    Francis.

    Hi
    I did exactly the same thing a couple of months ago so that I could save money with the white macbook versus the black. I bought a 120GB drive for my iBook and switched it with the shipped one when the machine arrived from the Apple Store. Result = I get a better specified machine than was available on line (and in white) and a removable 60GB drive with bus power, firewire 800/400 and USB 2.0.
    To get to the point buy one of these:
    http://discussions.apple.com/thread.jspa?threadID=736770&tstart=30
    works a dream, is neat and compact, comes with useful short wires, can be powered if necessary, and looks cool.
    I searched for a long time and the OWC enclosure was easily the best for me, even to import to the UK (i.e need to add on a few pounds sterling for customs - still way cheaper and better than alternatives).

  • Bluetooth is no longer available?

    Hello,
    I have both an Apple wireless keyboard A1016 and a wireless mightymouse A1197 and when I booted up this morning they were no longer available. I verified that the batteries were good and zapped the pram twice to no avail.
    When I type in bluetooth in the search window for the settings panel it says that the bluetooth tab is hidden because I don't have a bluetooth module installed or attached. Huh? It has been working just fine for the past couple of weeks. My system is completely updated up to 10.5.3.
    When I click on bluetooth in the system profiler it says: No information found.
    When I click on USB and then on USB IR receiver I get the following info (in case it's helpful): IR Receiver:
    Version: 1.07
    Bus Power (mA): 500
    Speed: Up to 12 Mb/sec
    Manufacturer: Apple Computer, Inc.
    Product ID: 0x8240
    Vendor ID: 0x05ac (Apple Computer, Inc.)
    I am kind of baffled by this and will be deeply disappointed if I have to go out and buy an aftermarket bluetooth dongle and wireless setup because this one is dysfunctional and unreliable.
    Thanks in advance for any help or guidance.

    Hello
    I have had the same problem for weeks now. I have read all the threads and lots of different machines have the same problem - In my case a first generation MacBookPro running 10.5.3
    I have tried pretty much everything suggested: a simple restart will not typically work. It requires a PRAM reset, sometimes twice. I have also noticed that it fluctuates: sometimes it will drop by itself (with no action or BT device connected) and it will restore itself on occasion too.
    A sure way to bring it down is to try to connect an Apple mouse or keyboard (both first generation): they will connect on a clean restart, but after a few seconds or minutes the BT not available 'zigzag' will come back.
    A collateral problem is that once the zigzag is 'active' it seem to screw up the PRAM: the machine no longer sleeps properly, wakes up by itself, drains the battery all the way to shutdown, etc.
    Like many people on this board I have tried everything: disk utility/permission repair, disk warrior, hardware tests, etc. I now have to set my PRAM several times a day and I am at the end of my tether!
    This reminds me the case when Apple denied problems with wifi under 10.5 and then magically cured it with the next OS update...
    Any ideas, Apple?

  • Can an aftermarket display tax the USB bus?

    I just had a very weird issue, I purchased a 22" samsung DVI display I got pretty cheap off of Ebay, I originally was using a 20" Cinema Display and love it, but I want like most of us I guess ,more real estate. The Samsung has no USB ports as the Apple display, which I guess for me is the first issue as I use a wireless keyboard connected to USB, A Digidesign MBox2 connected to USB a iLoc key and yeah, connected to USB AND my wireless USB aircard. I had to use my old Apple keyboard as a USB hub because I of course ran out of ports on the computer and no longer had any on the display, maybe that's my issue but I didn't think I had so much to load down the usb ports from the computer. My air card began acting erraically, my MBox2 died and upon reboot I got a message warning that USB device was no operational due to low power in the USB bus. Is my problem the fact that I don't have an additional powered USB hub anymore (cinema display)? or could the Samsung display be at fault? Going back to the 20" seems to have solved all my problems, so far. But I really want the larger size, However I don't want to spend on a USB hub unless I really have to.

    Hi-
    Your Samsung is not at fault.
    The hub in the Cinema Display has additional power, which helps with multiple devices.
    Using the keyboard hub is no good with unpowered devices, as there is no additional power to the ports.
    You just need a powered USB hub to connect all the other devices.

  • Bus powered external DVD burners risky?

    I am thinking of putting a second HD in my 1.83 MBP with the Maxupgrades kit , and getting an external DVD writer.
    Years ago I had a firewire bus powered Formac DVD writer, which took too much current out of my Ti powerbook and burnt the internal firewire bus.
    Are the modern generation of portable bus powered (USB2 and FW) such safe in this respect?
    I see that offering includes an internal battery. Why would they do that if the no-battery ones are OK?
    Thanks for any input.

    so the battery is not there to prevent overload of the USB port,
    I doubt it, though having a functioning battery may do so
    but so that the device can be used independently (from computer)
    Perhaps the drive could power headphones so you could listen to music, but the battery is there to provide additional life when you aren't plugged in. If your MBP normally gets 4 hours of life from a full charge, add that bus powered burner and it will drop - bigtime I'd expect. The extra battery in the device gives you a bit longer life.

  • IMAC USB BUS

    I have encountered a scenario where multiple video webcasting softwares will not work with 3 AGENT V5 usb webcams at once. Wirecast (software) tech has indicated to me it is (probably is) my IMAC's usb bus cannot handle the 3 camera's streaming at once and this is why I am only able to see 2 AGENT V%'s and my isight at ONCE in Wirecast options. This happens to ring true to me based on differing scenarios I have tried with Photobooth, Camtwist, BoinxTV.
    I was wondering if anyone has the math that would allow me to verify if the reason above is in fact the source of my problem? (I mac usb bus capability).
    I have 4 usb connectors on my new IMAC, they should all be able to be used at once...apparently not?

    I have nothing technical to add to Dah•veed's good comments, but one of these might be of interst.
    (1) If your multiple camera setup is for security purposes, you may be able to use your existing system with different software such as http://www.securityspy.com/ that uses a timelapse feature to reduce bandwidth requirements.
    (2) If your requirement is for actual streaming video, perhaps reducing the frame rate and dimensions of the video images might give you access to the additional streams you need. If you have not already considered them, it is possible that Apple's QuickTime Broadcaster and Streaming Server might be worth considering:
      • http://www.apple.com/quicktime/broadcaster/
      • http://www.apple.com/quicktime/streamingserver/
    They may not be easy to use, but they offer very powerful, professional-level, capability.
    (3) If you do not already know whether the problem is with limits internal to your Mac or might be related to your streaming connection's available bandwidth, you can check the latter for comparison against what you are paying for by using http://speedtest.net/

  • What's the largest capacity bus-powered external hard drive?

    I realize that this isn't a Mac specific question, but I'd really like a recommendation. What's the largest capacity bus-powered (preferably USB) external hard drive available. My new MBP has a 500GB drive so I would need something with probably 640GB or bigger. Problem is I can't find anything over 500GB that's bus-powered. Everything I've found requires an external power supply which is what I'm trying to avoid. If anyone has a recommendation, please share it.

    Have a search on the web for USA retailers who supply empty enclosures and drives separately. The enclosure is the physical case and the bits of circuitry and the physical ports. Tell them what you want and ask him what drives and enclosures he has to suit your purpose and if he can fit the two together for you. I have such a supplier but am in UK.
    Does it have to be a USB bus? Firewire is better and gives more power. One way I power a 360GB pocket drive is to feed from TWO USB ports on the computer into one input port on the drive(now in the enclosure) you should be able to buy a sort of "Y" shaped cable with two full size flat USB connectors at one end and one single connector at the drive end. The drive end often will be a mini usb port. What you want will depend upon the size of the input into the drive.

Maybe you are looking for
