Some PowerBooks, iBooks exhibit USB 2.0 port problems

One MacNN reader notes that some of Apple's newer laptops may exhibit USB 2.0 port problems: "It seems that on the newer aluminum-clad G4's (and iBooks with USB 2.0), when the computer goes to sleep, the USB port does not properly come back after waking up. Some USB 1.1 devices will power up and mount, but no USB 2.0 devices will. I have duplicated this with our devices and USB drives from M-Systems, C-One, Sony, Lexar and SanDisk. It affects Mac OS 10.2.7, 10.2.8, and I'm currently verifying it with all versions of 10.3. Interestingly, this problem does not happen with the G5. Different chipset, I guess?"

I agree with the USB 2.0 problems. I've noticed on my PowerBook G4 15" Alum. that after being asleep and then plug-in a USB drive in any of the two USB ports sometimes the USB drive will not mount and I have to reboot to make it work. A real pain sometimes.

Glad to hear I'm not the only one with this problem. I've had to reboot my 12 Aluminum G4 powerbook so many times just to get to recognize my USB 2.0 thumb drive or flash card readers. Very frusterating.

I noticed I could always duplicate the bug too. That is I could put the system to sleep, then wake it up, after waking it up, if I inserted a USB 2.0 device, it didn't recognize it. And sometimes, if the device was inserted before I put it to sleep, it would loose the device.

Thanks for posting your findings, until now thought I was alone, hopefully they'll find a good fix for it soon.

Even without sleep, USB does not always work with any brand of USB 1.1 or 2.0 flash memory devices.

the new Aluminum systems really SUCK.

I have this problem also and have told Apple using the OS X feedback page. All you other posters have notified Apple, right? The only way they'll fix it is if thousands of people complain about it.

Another me too post - this has been driving me nuts. I've replaced KVM's, cables, you name it.

Now let's see Apple fix this damned annoyance.

I've found that if I pull it out and replug it in it usually works, sometimes takes two or three times. Not the end of the world for me. Hopefully the bitching will get them to address it in future units, cuz if its a chipset thing don't expect new motherboards. I'd say that this problem makes me only 99.88% satisfied with my powerbook instead of 100%. You're right, these machines suck, let's sue!
