I tested the 2 cables I have and ac adapter that came with the n900 they work fine with my jabber cruiser 2. usb port definitely seems to have a issue. Talked with the seller and I will be shipping it back for refund, though will wait a couple days got 2 batteries and a stand alone charger coming hopefully they get here in day at most 2.

all the usb micro b male adapters had the hooks filed down so I didnt damage the usb port on the n900 I got. Again tested my jabber's usb micro b port and work fine with it.
