Sorry for the late reply, but why is HCHalted (above) normal? Looks like the HCD or controller hit a problem. Of course, it could be my problem... | > == after hot-plug == | > | > HC status | > usbcmd = 0008 Maxp32 EGSM | > usbstat = 0020 HCHalted | > usbint = 000f | > usbfrnum = (0)264 | > flbaseadd = 2b998264 | > sof = 40 | > stat1 = 0080 | > stat2 = 0080 | > Frame List | > Skeleton QH's | | This is odd. It says the USB controller in your computer is not aware | that anything has been plugged in. It's just as though no electrical | connection was made. In particular, look at the stat1 = 0080 line. The | least significant bit of that value is the Current Connection Status | indicator; the fact that it is 0 means the controller is unaware that | anything is attached to the port. | | Three possibilities: your USB controller is bad, your cable is bad, or | your USB device is bad. Since the same thing happens with multiple | devices (and also multiple cables?) we can rule out the last possibility | (and the second as well?).
