According to the TI documentation, the bridge chip first becomes active and contacts the host USB controller for some firmware. My USB controller could probably not handle this at the time, since it did not have the ehci_hcd driver autoloading. The bridge chip never got its information, therefore looked "dumb", with the Interface class and Sub Class not filled in. Eventually I got the driver to load (and loading nicely, thank you). Then I turned on the device and the bridge chip got its firmware, filled in the proper Class and Subclass, and everything was happy. Now, IF I had followed the instructions in the manual and had: o Plugged in the power to the drive first o Turned the drive on with the blue button o Plugged in the USB cable to the drive first o Plugged in the USB cable to the computer it *MAY* have worked first time, but I will never know unless I buy another one. Yes, they tell you to do that step-by-step. Silly me, I thought plugging in the power to the drive last would be the safest thing to do. and it may be....just not the first time. By the way, the TI documentation of their firmware start-up process was great. It even had flow charts. I can not remember the last time I saw a flow chart. I think it was when I was teaching CS over twenty years ago. md -- Jon "maddog" Hall Executive Director Linux International(R) email: [EMAIL PROTECTED] 80 Amherst St. Voice: +1.603.672.4557 Amherst, N.H. 03031-3032 U.S.A.
