Hi All,
I recently bought an external usb drive for my mythtv box. It is a passport 
western digital drive. The drive works on my labtop as well as my roommate's
labtop. however i cannot get it to work on my mythtv box. I'm guessing that for
some reason the USB bus isn't providing enough power since the drive is
running purely on the USB bus, there is no external power source. I have 
tried using a USB cable that has two USB plugs for devices that draw a lot 
of power, but that doesn't work either. My next step is to try a USB powered 
hub, whenever i can get my hands on one. Has anyone else has these problems or 
know of a solution? dmesg reports the following over and over with the only
difference being the sector reported by the OS at the end of the 2nd to last
line.
