in the past i have been able to plug in and unplug my phone to the usb of my pc without problem. now after the first time i connect the the pc after a pc reboot it is recognized but, then after i safely remove the usb connection and attempt to connect it again later it is not recognized. i have tried rebooting the phone, with debugging on, with debugging off, as mass media storage. i updated wmdc. reinstalled the phone drivers. i am stumped. i never had this trouble before. i have even been able to hot swap sd cards and and my pc would still see the phone.
