Hi, I have an externally powered USB HDD which I want to connect to my Home Theater (which has a USB port and the HDD can be connected to it) as well as my Time Machine (which uses it for my Time machine backup of my MBPs and other media related stuff) at the same time. Of course the Home Theater will perform read-only functions on the HDD whereas the Time machine will do read-write functions, i.e. there is no chance of the both the connections doing write at the same time. Is there any such device which I can use to connect to both the devices. It'll be a plus if I dont have to do a switching manually and both the device can access the USB HDD at the same time..
