PowerPC :: Powered USB Hub Won't Work - Not Even Pigtail Wire
Feb 26, 2009
I have a 15" PowerBook G4 1.33 Ghz and I discovered that the provided USB ports do not power such devices as portable hard drives or audio interfaces.
So I heard that you need a POWERED USB hub.
I get one, Plug it in. And the PowerBook still doesn't recognize my external hard drive.
My hard drive has two wires on the opposite side from the enclosure that connect to female USB ports. I run an extension cord from one of the males to the other USB port on the PowerBook which is said to work but that also does nothing.
i just opened my imac g4 1.25 ghz 17" (lamp imac) and found a wire that is taped at the end and apparently not connected somewhere.. as you can see in the pics, the one i'm holding with an orange tip at the tip.. i dont really know the history of this imac.. :c
is this a cause for concern on my part? i'm replacing/upgrading the dvd rom and hard disk.. that's why i saw that wire.
I had a powered USB hub attached to my computer, w/ a mouse and two printers attached to it. For a while, it seemed to work fine, but then the printers wouldn't work, and I had to connect them directly to the computer. I decided the problem must be with the hub, so I went out to MicroCenter and bought a new powered hub. Again, it seemed to work for a while, but then the printers again wouldn't work. There aren't enough USB ports to run all my peripherals so I have had to disconnect a backup USB hard disk. The hub is now disconnected entirely, and I have to switch connections around. Needless to say, this is a pain.

I bought a Belkin powered USB hub and hooked my MacBook Air Superdrive to it and it won't work. I was under the impression it would in a powered USB HUB. Anyone share any experiences with me on this?
I recently have been having start up problems, when I would hit the power button I would sometimes hear a healthy startup and everything would boot up and then I just get a black screen and you can still tell it has power. I would start and restart untill it would boot. Now the only way the machine will start is if I unplug the moniter cord and plug it back in then it will start.
I have a G5 / no iSight iMac. There is rumor that a power surge occured. When the machine is powered on, there are a few seconds of static, sounds a bit like pink noise, coming out of the internal speakers. After that, it will boot properly, and there's an occasional static sound. If there is no RAM in the machine, it obviously won't boot, but there is no static at all. Just that "tone" signaling the absence of RAM. Any ideas?
I have an snow iBook G3 that I use everyday as my machine for doing schoolwork etc., so it is a very critical machine. The battery doesn't hold a charge anymore, so I just plug it in. No big deal. However, just a few hours ago the iBook started to not recognize it was plugged in. The prong has always been bent a bit, I think, and it always worked (before MagSafe type). The charger is beat up at the cord going into the power brick from the wall outlet, but it has always worked too and it seems to be a problem with the prong going into the computer. I have to hold it a very certain way for it to even detect power. So, the machine has NO way to get any power. I was thinking about taking it in to the Apple store to see if they could still get me a non-magsafe charger, but what if its something different then the charger?
The specs are as follows: 12 inch iBook PowerPC G3 500 mhz 128 gb RAM
I have a Vista laptop I can use until its fixed, but I'd rather not use Windows. No speical prgrams or anything, I just really like Mac OSX. I have files on the iBook, too.
I have an old PowerBook G4 that my son uses for simple stuff. One day the screen went dark gray (not powered off) and it won't boot. When I try to boot from a Tiger disk, I get what appears to be a kernel panic. I don't get any strange startup beeps
I was thinking that if i bought an external MOBILE hard drive (un-powered) i could take it with me sometimes when i need it in UNI (in Lectures where there is no power source to plug drive in), but also attach it to the mac and since it is un-powered and mobile time machine will work without needing external power.
So, I've bought a new house (well, a very old house), and I'm having some work done on it, which includes getting Cat-5 and other comm. wiring installed.
I was thinking of dispensing with phone wiring, since I imagine in 5-10 years phones (cat-3 wiring) will be irrelevant and we'll be on VOIP. Instead, I figured I could get each room wired for 2 or 3 cat-5 (ethernet) jacks. In the meantime, I would use an adapter so I could plug a phone into the ethernet jack. Then at the patch panel in the basement, I'd use the same jack, and wire the phones together.
1) Does that adapter exist? I think it would be an RJ11 to RJ45 adapter.
2) Any problems with this plan? Obviously I'd be careful about which jack is for which, because I imagine that the ring signal wouldn't be so good to send to a computer.
I have 1 ethernet port which I share with my Netgear internet and my printer (Mac G4 via Asante talk). I keep switching the cords between printer and internet. Is there a easy solution ? Most of the time I have to reboot after switching ethernet wire.
My Fire wire port on my IMAC 24 inch is not working now. I have tried switching cables, etc. This started when I had to have the hard drive replaced. The drives do work if connected by USB or FW 400.

I have a 15" mac book pro with 4G of ram and 320G of HD.
Due to the internal HD filling up, I have decide to install a new internal HD myself which will be with me in the next few days. Installing the HD I have no issues with its the loading up of the new HD that I�m a little unsure of.
Until a few days ago my time capsule was a 320G Western Digital fire wire 800, which has worked well but is now full, this coupled with the need to back up my girlfriends Mac book I decided to buy a Time Capsule, which I made the default. However it took 24hrs to back up 200G wirelessly and the girlfriends Mac book via Ethernet is not going much quicker (only 80G).
My question is this, when I have installed my new internal HD would it be better to restore from the external hard drive or from the time capsule bearing in mind it took nearly 24hs in the first instance?
I am thinking of using either superdupper or carbon copy cloner will my external drive be OK to boot up from it is as followsFreecom 1TB fire wire P/N 31252
i have been reading all the post regarding the bluetooth issues with the wireless keyboard and mouse. Now base on that, is it worthy getting the wireless KB and MM from apple, or should i get wire KB and MM?
I tried to re-apply the thermal paste myself but when it came to disconnecting the wire connectors from the logic board, 3 of the connectors came off completely from the logic board or has damaged the pins. (the battery connection, and two for the left fan)
I have a feeling that these three became brittle or weak from the heat that was generated from the laptop (hence i wanted to do the thermal paste mod). Or it's just my stupidity that these broke. But the others came off without a problem.
I am trying to test the coolant pumps on my g5 because one cpu is overheating and there are no coolant leaks, there are 2 Delphi pumps each with 4 wires, they are connected to a black 12 way plug. I am wondering if I can connect a 12v supply to the pumps to check that they function OK..
Just had to replace the logic board on my PMG4 DP 1.25GHz machine. For the life of me, I can't remember the operating temperature before I swapped the board. Currently it's running at 130F - 140F. This seem about right for the other folks running these machines?
I have a modem (Tilgin Vood 342) that came from the phone company which I use to connect my old desktop PC and my new MacBook Pro to the internet, through two separate ethernet cables. The modem has three ethernet ports and connects to the internet through an ethernet port in the wall. I want to buy an Airport Express in order to get wireless internet to my MacBook, but since my desktop PC can't receive wireless internet, I still need it to be plugged into the modem through a cable (I don't mind that). So my question is, can I use one of the modem ports for the Airport Express and another for the ethernet cable without there being a conflict?
I'm asking because I went to an electronics store and I was told that there might be a conflict and that I should buy an Airport Extreme or another router with ports in order for it to work. I would really prefer the Express because it's and it's the most I can pay for.
One day I couldnt wake my macbook from sleep with my firewire WD Mybook 500G connected, so I power off the macbook manually and start it up again. It then triggered kernel panic, and i found that my macbook resume normal if i do not connect the firewire external HD. I performed PRAM reset and even PMU reset but it still couldnt help.

now that windows 7 (64) is working properly another question came up. Does win7 support fire wire because my external MyBook does not mount when I connect it to my iMac with fire wire 800.
while trying to make a presentation or simply playing a video from my MacBookAir over thunderbolt/HDMI table to large screen I am experiencing problems with audio only being played from the MBA and not the soundsystem built in to that screen (unless using a VLS application and manually selecting the audio output target).
how to steer audio output device using 2in1 cable such as thunderbolt?

I love my iMac but the one thing I hate is that it only has 4 USB ports...
I have 3 USB 2.0 External Drives.... My digital camera, iPhone, iPad, Kodak Zi8, Elgato Eye, and Harmon/Kardon Sound Sticks... and a few other USB devices...
Can anyone suggest a good Powered USB hub? I have this little 4 port laptop USB hub.. right now, but my external keep disconnecting..
I have a problem with Disk Utility , when trying to format an external fire wire drive.
I cleaned out the drive and proceeded to erase it with zeros. After this Disk utility will not display the subdirectory or verify, repair, partition, erase the disk. The main disk name is still visible, but I cant access any functions. Error message says input output error.
DiskWarrior will not help, as the original directory is beyond recovery.
I suppose that I have damaged the original directory, and now I would ask the honourable forum if there is any remedy for my actions?
Imac, osx Leopard. Was working fine for many months (except for the 27 vertical lines but won't bore you with that), I bought a powered usb2 hub to power a usb hard-drive, when connecting the hub after a few minutes the Internet connection stopped and does so any time I connect the hub, now without the hub being connected the internet stops and starts every few minutes making it impossible to do any work. Other macs in the house are unaffected (s I'm having to write this on a minimac). Has something damaged the imac for good ?
I occasionally have trouble charging my iPhone via my iMac USB ports. I plug in the iPhone, the screen indicators change to show that the phone is charging (green battery indicator and the lightning bolt symbol). However, when I come back to the phone several hours later, the charge indicator hasn't advanced any. For example, if the indicator showed half-full when I plugged it in, it remains half-full.
The iMac does go to sleep a few minutes after I leave it, but sleep has never precluded an iPhone battery charge on my MacBook, and most of the time it works on the iMac.
Is there anything, besides shutting down a computer, that causes a USB port to unpower while the iMac is sleeping? Does it matter whether I am logged in or simply at the login screen?
I recently got a Macbook and have a iPhone and iPod shuffle. The thing is there isn't enough usb ports on the Macbook so I had to get a hub. The hub I got IS self powered and does not require a external power adapter. My concern is that I am withdrawing too much power from my usb port through this hub. It is a 4 port hub and a External HDD ( has own power supply), Optical mouse is connected to it. also I charge my iPhone and shuffle via the same hub.
I am afraid that there is power limit feature and it will fry my computer. I notice if I boot in boot camp to windows. Windows will display a error message telling me, I am not allowed to have this many device drawing this much power. Anyone know if I should be okay as long as OS X doesn't give me a message or should I really consider getting a USB hub with its own power adaptor?
