Thanks for the response! I have put the complete verbose dmesg from new boot, insert of usb memory, sleep, resume, (doesn't work), kldunload/kldload uhci/ehci, insert usb memory, (works again), and a log of the shell session covering the same here: http://www.sics.se/~bengta/fcd49b361c6d9b06b5d7e6adc2349629/ Both have annotations "==== " for clarity. Is it worthwhile to compile with USB_DEBUG and redo the above? Bengt
