I have a weird problem. I can connect my android phone to my laptop, it keeps connecting/disconnecting (about twice per second). I tried on another laptop with Ubuntu installed, and it worked fine.
Big problem is that, aside of no file transfer, I can't charge my phone. I keep getting the message "unable to open MTP device '[usb:003,]'", where num keeps increasing (I assume it is communication attempts).
What may be causing this problem? I have no idea where to start. It's the only USB device that does that (my ipod charges fine, and I can even access the music no problem).
Is there a way I can "deaden" one of the usb ports, such that only power is provided, but no data transfer attempts?
P.S.: My phone is a Samsung Galaxy S2.
P.P.S: It does that on all USB ports.
