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
4
[17181262.172000] usb 3-1: configuration #1 chosen from 1 choice

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

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.
