just got my HTC evo 4g today, its about 8 hours old. hooked it up to computer and everything worked fine transfered a few videos to SD card all was good. charged phone as battery was dead, then plugged into computer again and now it wont recognize HTC sync program on computer and computer wont recognize SD card if i tell it to be a disk drive, wont recognize with htc sync on computer and computer wont even acknowledge that the phone is plugged in. the phone will charge via usb plug in but thats all it will do, further more, if i plug it in and it fails to work like its supposed to, then the phone says i have no SD card installed in it... even if there is. and i have to reboot the phone to get the sd card mounted on the phone again. anyone else have this problem?
