    I'm having USB bandwidth limitation issue with my TV tuners. Never have this issue with Tiger. I'm sure Leopard has some USB issues as I have folks reported that some USB devices don't work properly after the upgrade.

    I am using a Logitech MX 518. After closing and reopening the lid, it doesn't work anymore till i plug it into another usb-port.

    My USB peripherals seem to randomly stop working after installing Leopard, particularly the aluminum keyboard. Unplugging the usb and plugging it back in gets it working again.

    Try things in this USB faq. Do the Combo Update too.

    I got my new macbook with Leopard preinstalled, and yes I have problem with USB on one of the port. The problem is only with external device like disk which doesn't have it's own power. I even suspected it was the problem of the logic board, that I have it replaced at the apple center, but the problem won't go away.

    Tried to install vista using bootcamp, and both USB ports recognized just fine by windows. So probem with Leopard?

    I have several problems with USB issues since I've installed Leopard. With both 10.5 and 10.5.1 (maybe even worse in 10.5.1). On my main workstation a Mac Pro, after varying periods of time the box will kernel panic with various USB traces, or the mouse and keyboard and all USB devices just stop responding. It's rendering my workstation useless.

    I'm really hoping there is a patch for this soon.

    Am having similar issues on my Mac, my EyeTV used to work perfectly under Leopard now it records when it feels like it, sometimes none of my USB devices except the keyboard works and Bluetooth has conked out a few times as well, overall am not that impressed with Leopard, but cant get my Tiger install on my external drive to boot up for some reason!. Apple had better fix it soon!

    I've had problems with many USB devices after upgrading to Leopard. Particularly the ipod and my Blackberry Pearl. If the ipod is plugged in during startup, the computer will not boot. Once when I plugged the Pearl into a port in the back of the computer and the computer rebooted itself. Needless to say I avoid that port now and am wary of plugging in my ipod in any port.

    I am experiencing problems with the sleep mode on my MBP. Some on this forum say its related to the USB. Usually when I wake from sleep, if it does wake successfully, my bluetooth Mighty Mouse and keyboard behave erratically.

    I had a problem with usb in my new black macbook..

    If I plug in my Toshiba HD in the left port it not showing me any HD icon on desktop and the usb stop working! and I can't use it any more with any device ( like usb mouse ..etc) tell I restart the system. the right port it's working fine without problem.

    But after that I test it with GNU/LINUX Fedora Core 8 Live CD and the 2 ports working perfectly without any problem! (with my HD too).

    So I think the problem it's about software not hardware!

    Sorry for my bad english language, because it 's not my mother language.

    I'd like to echo others' experiences.

    My previously-perfect MacBook C2D 2GHz (2GB) now has hilariously basic USB I/O issues, including:
    - poor data transfer rates from USB flash storage devices; both data rate and CPU load during Finder copies are fluctuating randomly
    - data rates are sometimes so bad it feels like USB1.1 on USB2 devices
    - very serious random disconnections of USB storage devices, often during copies
    - built-in USB bluetooth module occasionally appears to go missing; the OS says BlueTooth is 'not available'; does not see the module again until a reboot

    In Leopard (unlike Tiger), the console is a constant trickle of runtime errors (many serious, most unreported at GUI level) indicating that many parts of the OS are in a chaotic state and are in difficulty. USB is no exception; here is my console during a finder copy to a known-good 4GB USB flash key:

    Dec 27 17:43:05 odysseus kernel[0]: disk2s1: device/channel is not attached.
    Dec 27 17:43:05 odysseus kernel[0]:

    The copy failed and the OS accused me of unplugging the device. This is remedial; it embarassed me in front of a Windows-using friend. Under Tiger, I would have been dumbfounded at this.

    Yesterday I noticed my BlueTooth module had taken the day off. Here's what appeared in the console:
    Dec 24 23:21:36 localhost kernel[0]: E:[AppleUSBBluetoothHCIController][StartInterruptPipeRead] there is alredy a pending read, skipping.
    Dec 24 23:21:36 localhost kernel[0]: [InterruptReadHandler] Received kIODeviceNotResponding error - retrying: 1.

    I had to reboot, and guess what? The Bluetooth module re-appeared. Again, remedial. Under Tiger, I rarely had to reboot the machine for any reason other than patching.

    These USB devices all worked beautifully under 10.4.x, as did BlueTooth. Only Leopard can be to blame. It's clear that (at the very least) kernel extensions for USB are very buggy. Why have even these parts of the OS disintegrated like this? Tiger was rock solid in comparison.

    General comment: I'm having so many issues with Leopard (too many to list here) that for the first time in 6 years of using Mac OS X (and over 20 years on the Mac platform) I have recommended anyone who asks me to stick with the previous release, perhaps for another two years. That's how much my confidence in this once-superlative operating system has been shaken.
