Got to do this sooner than I thought and the diags are attached. The
blah.post-boot.txt snapshots are taken after the system has booted but before
any usb device is attached. the blah.post-cf.txt ones are taken after my
compact flash adapter has been plugged directly into the laptop's usb port.

I've also built and tried 2.6.3 and it _works_ fine with all the devices. I
can plug the wireless, IrDA and CF adapters directly into the laptop or via
the hub and they work fine (well, actually there are no drivers for the IrDA
adapter in 2.6.3, but it is listed by lsusb and dmesg shows no error
messages, so I'll count that as OK)
Looking forward to advice :)
