Currently Being ModeratedNov 27, 2006 5:33 PM (in response to Steve Phillippy)Just to let you know, I don;t think it is an issue with Intel based Macs. I have many similar USB devices, cameras, card readers, printers, scanners, etc, and have not had any problems with USB devices.
However, one common upgrading process that is known to have a few problems is when you migrate applications, drivers, and other files from a PPC based Mac to an Intel Mac. In many cases the use of the migration assistant to transfer settings can produce problems, including the ones you have mentions.
You may want to try removing most your USB device, including any drivers or installation files that may have been part of their install, then pick one device, maybe your printer, and then reinstall the device and its needed drivers, then test and go on from there.
If you still have issues, you may wish to consider doing a re-install of the OS from scratch, to ensure that no old PPC files are present.

Good thought and thanks for the reply.g5, Mac OS X (10.4.5)

Using a hub or straight to the Mac Pro? I have no issues. I use a Belkin USB Hub.

Currently Being ModeratedNov 28, 2006 3:05 PM (in response to Steve Phillippy)Hey, just to chime in, I'm not convinced yet that it's a problem of architecture even though I sort of "feel" like I get more USB device related problems (mostly removeable media/drives).
Some of the USB thumb drive problems that are reported are interesting - I tend to think that my own problems come from the formatting of the drive. I use the FAT16 formatting in case I'm stuck in the PC world, and I think it might be something to do with either (a) the format compatibility (less than native, let's say) or possibly the architecture of the cheap thumb drive I'm using.

Currently Being ModeratedNov 28, 2006 11:09 PM (in response to Steve Phillippy)I've also seen some odd behavior with USB devices on my mac pro; most disturbing is the whole system locking up (with the spinning pizza thing) during heavy transfers to/from USB storage devices, including my ipod. Seems out of place on a machine as heavyweight as the mac pro.Mac Pro Quad Xeon 2.66, Mac OS X (10.4.7)
Currently Being ModeratedNov 29, 2006 2:31 AM (in response to Steve Phillippy)Hi,
I have similar issue with My new Mac Pro 3GH Dual-Core Xeon is USB port too, ecently I keeps encountered the same annoying problem...
My Mac Pro can't recognize the USB pen drives when I or my co-worker plug into Mac Pro's USB port.
For a few times, if we are lucky, Mac Pro shows the pen drive on the desk top, but sometimes it can't read or write the data from/to the pen drive at all, many times, it simply freeze over.
Luckyly, during the Thanksgiving long weekend, I think I might accidentally singled out the cause of my problem.
I have my HP printer and one multi-card reader constantly pluged into the two USB ports at the back of my Mac, and always tried to use the front side USB ports for the 1GB USB Pen Drives, and that's where the problem lays!
When I unplug the Multi Card Reader from the back USB port, and suddenly all USB ports on my Mac works just fine with the Pen Drives!!!
So, for now, I plug the Multi Card Reader in one the the front USB port, and the rest of the USB ports on the Mac work with Pen Drives flawlessly, it seems that I sloved my problem for the time being...
As for those two USB ports on the back of my 23" Apple Display, They can not take my USB Pen Drives, cause it does not have enough power for the USB Pen Drives.
Just try to provide my own experience with this issue, hope it will help a little...

Currently Being ModeratedNov 29, 2006 4:37 AM (in response to Steve Phillippy)While I feel for you, I did want to chime in and say that I've had zero problems hooking up scanners, printers, my iPod, my camera, my card reader to my MacPro.
Since your setup works on your laptop then may I suggest there may be something defective with your MacPro. Did you run the Apple Hardware Test (found on your install disc and you boot into it by holding the D key).

Currently Being ModeratedNov 29, 2006 7:00 AM (in response to Michael Flynn)I haven't tried the apple test thing yet, it may come to that. I like the idea that I may have an item or two which could be screwing up the USB ports, as I have none plugged in my laptop except mouse, this could very well be the problem. This day every add-on you buy is USB. (I have 2 printers, camera, mic, mouse, Keyboard, digital movie cam, iPod) I'm thinking another USB card may be the ticket - you'd think even if an item is plugged in - if its not being used it wouldn't be a draw on the system. (Yes I have 2 hubs and both are external powered). Thanks for the responses, I'll let you guys know.g5, Mac OS X (10.4.5)

I used to have a G5 and "upgraded" it to the new mac
Never had issues with USB devices, but now printers
suddenly stop being "seen" data is dropped, and my
digital camera locks up the computer - requiring me
to unplug it (then I get the dreaded message about
device not removed properly) I've tried plugging
items directly into computer (no hub), turning off
all devices but one in use, restarting, with only
minimal success. Any ideas?
Yes I have latest firmware. (PS Devices all work
flawlessly in my laptop (NOT intel

I suspect device incompatibilities....I had the same problems. Suspecting my older Belkin USB hub, I replaced with a new one. The problems went away, but a new one showed up. The mac wouldnt sleep, and sometimes crashed when placed in sleep mode. I tested it with each USB device unplugged, and the culprit appears to be my SanDisk 12 in 1 card reader/writer, whether connected to the Hub or directly to the front USB port.

Currently Being ModeratedJan 26, 2007 5:49 PM (in response to Kev C)I noticed the exact same thing on my Mac Pro.
When I have my printer and my video ipod plugged into the mac and plug in my media card reader the computer locks up.
I later noticed that when the printer and the media card reader was plugged into the mac, the ipod would not mount nor would it even charge when it was the last device to be plugged in.
Not sure what's happening but I can not have the ipod and the media card reader both attached to my machine at the same time.
If anyone is wondering, all the devices are being plugged in directly to the machine without using a hub.

Currently Being ModeratedJan 27, 2007 3:01 AM (in response to Robins)I have just bought a MacPro, and experienced the same sleep problems. As far as I can tell, it was my Lexmark laser printer stopping the MacPro from sleeping. I have to make sure it's turned off before putting the Mac to sleep. So far, that's the only USB related issue I've had with it.
