Hey there just thought id share a stroy of my own that i think fits your problem perfect.
i have windows 7 on my pc and had that same problem with a phantasm v3 staff. i spent soooo much i was expecting it to be perfect and after a month it still snt;) will be tho soon;) the usb port not recognizing it is thje exact situation i had and all i had to do is contact deep. (
[email protected]) and told him. he promptly told me i need to send it in for repair. i did and he is fixing it up, well was, it shippiied out a few days ago and should be home any day:) long story short, just email Deep and ask for a usb repair and he will probably say ship it back and ur problem will be eliminated:)
