This is a problem with the connected device. My expirience about this is that such devices have bad oscillator designs and notebooks tend to have a worse power quality - especialy when running on batteries. I asume that most of this device work if you give them more time to get ready after connecting than required by specs. It seems that we already wait longer than required, but you can try to increase USB_PORT_POWERUP_DELAY in src/sys/dev/usb/usb.h a bit more. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
