USB Hub versus PCI Card?
Hello, I have a G4 MDD that only came with 2 (4 if you count the keyboard) usb ports. I am not very concerned with the 1.0 versus 2.0, so considering that - my question is this: Should I get a usb pci card or just a usb hub? If I do get a pci card are they specific to the platform (i.e. mac/pc) or will any usb pci work on a mac? -Jeff _ Hotmail® goes with you. http://windowslive.com/Tutorial/Hotmail/Mobile?ocid=TXT_TAGLM_WL_HM_Tutorial_Mobile1_052009 --~--~-~--~~~---~--~~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: USB Hub versus PCI Card?
Howdy, A hub is cheap, and works for a lot of things. What do you want to plug in? Each USB hub on the computer can drive .5 amps. If you are plugging in multiple devices that need power, you may need a powered hub or the pci card. Not all PCI USB cards work in the Mac. Look in the archives for messages about that, or wait for further responses here. If I knew specifics on that, I'd give it to you. I remember having to be carefule when I bought my PCI USB 2.0 card.

The keyboard and mouse are two, so that port can only have 2 (or 3?) more. I would go for a PCI card with 4 ports. It seems I am always looking for another port. I hate dragging the mac out where I can get at the ports. I have a couple of extension cables to help, but then there are cables running everywhere. My MDD is loaded up with things and I even have a Firewire card to add ports.

RE: USB Hub versus PCI Card?
Hello Thanks!, I found this post when searching the group - looks like if i get a card with the chipset NEC, ALI, TI or OPTI it should work.

Any USB port is rated at a maximum of 500mA (it could be less) and a minimum of 100mA. Any device plugged in automatically is allocated 100mA. To get more it has to tell the computer how much it needs. If the computer allows it the device can then draw more. If you have an un-powered hub the hub itself takes 100mA so it (and the computer) can dole out 400mA to 1-4 ports on the hub. But if the hub is powered every port can use up to 500mA. If you branch out from the computer port using powered hubs you can go up to 127 devices. I believe each hub counts as one device in that total. There are 7 port USB hubs, they are always powered. By powered hub I'm referring to an external power supply connected to the hub. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting I'm a designated driver on the Information Super Highway --~--~-~--~~~---~--~~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: USB Hub versus PCI Card?
I had problems before where a USB Hub might have been a better choice, but ... Out of curiosity, since I'd replaced my QS 2002 Dual mobo, I'm again trying my adaptec Duoconnect AUA-3020A USB 2.0 / FW400 PCI card alongside my M-Audio 2496 PCI audio card. Seems to be functioning - playing back iTunes music through the audio card and scanning on my Nikon Coolscan 5000, saving to disk via the USB 2.0 adaptec port. No hiccups at this early date. Has an NEC chipset if I read the right chip on the card before inserting it: NEC Japan D720 101GT, etc. More info on the card and connected device: USB High-Speed Bus: Host Controller Location:Expansion Slot Host Controller Driver: AppleUSBEHCI PCI Device ID: 0x00e0 PCI Revision ID: 0x0004 PCI Vendor ID: 0x1033 Bus Number: 0x54 LS-5000 ED: Product ID: 0x4002 Vendor ID: 0x04b0 (Nikon Corporation) Version: 1.02 Speed: Up to 480 Mb/sec Manufacturer:Nikon Location ID: 0x5450 Current Available (mA): 500 Current Required (mA): Unknown (Device has not been configured) AFAIK, Adaptec no longer officially supports the card much past OS 9 ... so insert one at your own risk ... --~--~-~--~~~---~--~~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

I was running at the time Mac OS 9 + Mac OS 10.2 on a Beige G3, and both systems did not recognized it. The driver doesn't work under OS 9 at all, it's strictly OS X. If you notice, there are multiple versions of the OS X driver, one for each version of OS X. I suspect you installed the driver for 10.3 10.4 on a 10.2 system? Perhaps try again by deleting the driver you installed and using the correct version. You'd need to click the tiny Old Drivers link of the page I posted and use the v.1.10 for Jaguar or 1.50 driver for Panther. The 1.60 driver was for Tiger. OS 10.2 isn't very good for USB, both Panther and Tiger are large improvements for USB. The Beige G3 isn't very good for PCI cards (the Beige has a PCI 1.0 bus, whereas almost all PCI cards are PCI 1.1 or newer, so some VIA USB cards won't work, but it's not the fault of the driver or the card, it's the fault of the PCI bus on the Mac). --~--~-~--~~~---~--~~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Flash Drive Issue
I have a Sony monitor that has 4 USB ports on it.
Earlier tonight I stuck a 3rd flash drive in and it came up (name
shown: Kingston I). I saved 2 files to it and was saving a 3rd when I
saw a message saying something about it being removed and the files
might be messed up {I forget the exact message}. Problem isI did
NOT remove it.
What might have caused this? Is there some reason I cannot put 4 USB
Flash Drives on this thing?
The setup is this:
Smurf has 2 USB ports
1) My Logitech USB Mouse
2) The Sony Monitor (lists it as a Hub in the Apple System Profile)
Also shows the 2 USB Flash Drives plugged into it

Is that port a bit loose? I have one on my QS ... whatever's plugged
in needs to stay very still ... otherwise its a bit flaky ...
