What SVN/P4 version did you test? Recently I have added a lot of sync code to help out on non-x86 processors. What kind of processor are you using? Could you do something like "sysctl hw.usb.debug=15" before you plug your memory sticks. Then afterwards "sysctl hw.usb.debug=0". Post or send me the resulting debug output. > usb2: <EHCI (generic) USB 2.0 controller> on ehci0 > usb0: USB revision 1.0 > usb1: USB revision 1.0 > usb2: USB revision 2.0 > usbd_fill_iface_data: invalid wMaxPacketSize=0x0000, addr=126! > usbd_fill_iface_data: invalid wMaxPacketSize=0x0000, addr=126! > usbd_fill_iface_data: invalid wMaxPacketSize=0x0000, addr=126! This error clearly indicates that something is wrong. wMaxPacketSize should never be zero with a few rare exceptions. > uhub_explore: usb_new_device failed, error=USBD_TIMEOUT > uhub2: device problem (USBD_TIMEOUT), disabling port 6 > The transfer timed out. How nice. --HPS
