Public bug reported:

I don't think usbutils is the correct package for this bug, but it won't
let me choose linux-image and I am not sure what the correct package is
- linux-image, hal, dbus, etc.  The kernel seems like a good place to
start.

Bug description:

I have a laptop that has 3 USB ports.  Two of them generally work fine,
but one of the ports does not recognize or inconsistently recognizes
many devices.  A simple example, is a USB key I have.  In the other two
ports, the following very standard exchange is seen in the output of
dmesg when the key is inserted:

[17181261.944000] usb 3-1: new full speed USB device using uhci_hcd and address

On the third port, inserting the USB key generates the following
exchange:

(error=-84)

It appears to repeatedly try to connect the device and fail.  This sort
of things keeps going for as long as I keep the key inserted.

This same port has problems with many other devices, but simple devices
like mice work fine.  I have also tried this same USB port with the same
computer and USB key when booted into Windows and the key works fine.

I am using an up to date Edgy Eft installation.

I will attach the output of lsusb -v to this bug as a file.
