This is likely a new problem introduced with new USB power management
in Leopard.
Unfortunately, we don't know when an update with the fix will be
available. You might try disabling Bluetooth (if you don't need it)
and see if that helps.
Meanwhile, it sounds like you have a work-around with using a USB hub.

Greetings again,
I had posted last week with a question about usb ports not resuming
correctly after sleep, since then I have had a chance to do a
little more research into the problem, and I'm hoping this
additional information may allow someone on this list to possibly
point me in the correct direction. Although a longtime engineer, I
am new to the Mac. This one (24 inch 2.8Ghz intel iMac w/ 10.5
installed from the disk included in the box with the Mac) is brand
new (a couple of weeks old) and nothing has been done to it. It
has no third party drivers installed (I had installed MS
IntelliPoint for better mouse control, but uninstalled it after I
first noticed this problem. It didn't make any difference.) It is
literally about like it was when I opened the box.
To Recap:
The problem seems to occur only when all three physical usb ports
on the Mac itself are used. It doesn't mater what is plugged into
them as long as all three are used. The ports fail sequentially,
one after each sleep (see below). If I only use two of them, and
it doesn't seem to matter which two, all is good. It looks from
the outside as if the failed ports have been suspended by the host.
I can, however, plug all the usb things I want into an external hub
(I have five things plugged into the hub right now and everything
is working fine) as long as I don't have more than two things
plugged directly into the Mac itself. To Sum Up:
With (any) three usb things plugged directly into the Mac itself:
Boot - All good.
Sleep/Wake - Rightmost (looking at back of Mac) port not working.
Sleep/Wake again - Middle port now also not working.
Sleep/Wake again - Leftmost port now also not working. Keyboard/
mouse now dead so have to use power switch to....
Reboot - All good again.
With two or fewer things plugged into the Mac itself, sleep/wake
works fine.
The failed ports cannot be brought back to life externally;
disconnecting/connecting a device from a failed port has no effect.
With the right port = LaserJet, middle port = flash drive, and left
port = powered hub with keyboard, mouse, and external hard drive,
here is what the logs say...
After first sleep after reboot:
system.log
Nov 11 15:35:08 Macintosh kernel[0]: USB caused wake event (EHCI)

And the usb logger (level 7) says:

to be suspended for conversion, but it is not!!
Putting it the Mac to sleep and waking it a second time causes the
middle port to fail and once again produces this in the system.log:

Nov 11 15:48:15 Macintosh kernel[0]: AppleUSBHub::setPowerState

1571.791 [1] ControlTransaction: control packet 1 error 0xe0004057
After a third sleep, the left port has apparently failed and since
the keyboard and mouse are connected on that port I can't get any
additional information from the computer after that. The hard
drive connected to the hub on the left port is also spun down and
appears suspended. I have to reboot the Mac using the power
switch, but then everything is fine again.
I am stumped, and a (rather long) drive to an Apple Store didn't
resolve the problem. For the time being I am using the Mac with
only two of its usb ports in use, everything else is plugged into
an external hub. But I really need to get this problem resolved.
Is it a hardware problem? A driver/OS bug? Something we can fix
here? I really need to know. Any help would be very greatly
appreciated.
Thanks in advance,
Mark
