>From the looks of the rear of the case, it could use a wall wart, there is a plugin that says 5 [EMAIL PROTECTED] amps next to it, but it didn't come with one. When on the lappy, it spins up and works just fine with only one of the dual connector cables plugged in. The led in the front of the case is just as bright when plugged into a port on this box as it is when plugged into the lappy, hence my reticence to blame the power gods. Since its only a 4 wire connection, I'm not sure how it could effect a non-spinup and still have a nice bright white led which blinks when theres traffic. As a C.E.T. and electron chaser for at least 55 years now, that doesn't grok, so it stands to reason there may be some sort of an enabling command sent from the lappy that is not being sent when its plugged into this box due to a missing module. This is 2.6.22-rc7-cfs-v18, whereas the lappy is running a stock, fairly recent FC5 issued kernel. Or at least that's the current theory. >Try turning on CONFIG_USB_STORAGE_DEBUG and see what shows up in the >debugging log. Done, and the build is underway, or maybe even finished. Yup, done, so I'll save this and reboot, brb. Humm, interesting, when I rebooted it was still plugged into the front panel hub, a 1.1 hub. And it would not complete the bus scan in post! I tried to get its attention from the keyboard via the usual vulcan nerve pinch etc, finally got up and walked around to unplug it. I was going to hit the reset button, but the floppies started seeking the instant I unplugged it and before I could hit the button and the post completed normally. Now, to plug it in after unplugging something else and tail the log. It still takes about 1 minute to give up, and the log is no more verbose than it was.

Its plugged into an Alps 7 port USB2.0 hub, which is itself powered from the USB cable plugged into a 2.0 port on the rear of the mobo, and everything else plugged into it is working with no obvious problems. > >Alan Stern -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
