me too (again!)

[   95.408000] Suspending device 3-1
[   95.408000] suspend_device(): usb_generic_suspend+0x0/0x144 [usbcore]() returns -16
[   95.408000] Could not suspend device 3-1: error -16
[   95.412000] Some devices failed to suspend
[   95.412000] Restarting tasks... done

rmmod-ing sd_mod usb_storage usbhid uhci_hcd can finally suspend to disk
and resume (s2ram).
usbcore tells it is in use (count=1) and can't remove it.
The device is a memory stick reader.

I have the same problems also with suspend to disk. BTW I can't resume
from disk since 2.6.17-rc5-mm1, but I'll try to be more precise
tomorrow, as it seems removing the usb stuff makes it do some more steps
toward resumimg (eg: with usb modules this laptop immediately reboots
after reading all pages, without them I can reach "resuming device.."
stage).
