>Environment:
Toshiba Satellite 2140 XCDS running 1.4Y as of 20000524.
The machine's USB devices are found as:

ohci0 at pci0 dev 11 function 0: NEC USB Host Controller (rev. 0x02)
ohci0: interrupting at irq 11
ohci0: OHCI version 1.0
usb0 at ohci0: USB revision 1.0
uhub0 at usb0
uhub0: NEC OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered


>Description:

Using a Toshiba Satellite 2140 XCDS and a 3COM usb->ethernet adapter I
get:


kue0 at uhub0 port 1
kue0: 3COM 3COM HomeConnect Ethernet USB Adapter (3C460), rev 1.00/0.05,
addr 2
kue0: cold boot, downloading firmware
kue0: failed to load code segment: TIMEOUT
kue0: loading firmware failed

The machine has USB on a ohci.  The same device has worked before on
another Toshiba machine (Satellite 2640XDVD) that had USB on a uhci.


Worse now, unplugging the device:

uhub0: port error, restarting port 1
kue0: at uhub0 port 1 (addr 2) disconnected
kue0 detached
usb_transfer_complete: bad dequeue 0xc058b800 != 0x0
panic: ohci_add_done: addr 0x01b42710 not found

Stopped at     cpu_Debugger+0x4:    leave
