It also seems that the USB controller/serial PCMCIA card described here: http://www.ka9q.net/5220.html
does not work under 2.6.5-rc2-mm1 either. It is recognized in lspci as that page says it should, but it isn't fully set up by ohci_hcd nor do the USB serial devices attached to the controller show up. The following is the only relevant output from /proc/bus/usb/devices:
What does alt-sysrq-T show is happening when this flakey "devices" output appears? It's hiding the root hub strings ... very wierd. Something probably happened _before_ that "relevant" section.
One experiment: "modprobe ohci_hcd power_switching". Maybe your controller is wired so that works. When it works, it sometimes gets rid of problems by enabling a more complete enumeration. (If you have an external bus-powered hub with power LED, and that LED goes off when you "rmmod ohci_hcd", power switching works.)
If you can show the /sys/class/usb_host/usb5/registers file (which you should have, you seem to have CONFIG_USB_DEBUG), that may be useful too. Preferably along with the "async" file, while it's hitting this "not accepting address" error; there'll be retries, 5 seconds each, during which the "async" file will have contents.
Is this an x86 laptop, or does it use some other processor?
What's suggestive to me is that your card uses the Lucent OHCI. One person mentioned some strange quirks with that, and I suspect that some recent (2.6.4) bugfixes might have provoked them ... or maybe more likely, uncovered a different bug. In any case, please send along "lspci -nvv" output for that card too.
