device descriptor read error
Some USB controllers will be loaded with the wrong USB standard applied (e.g. a USB 3.0 controller is initialized with a USB 2.0 kernel module assigned) causing a loss of performance and an error message that looks something like "device descriptor read/64, error -32" at boot time. A supposed fix I found involves issuing the following command as root: "echo -1 >/sys/module/usbcore/parameters/autosuspend". Since I don't have a USB storage device handy it's hard for me to verify that the performance impact was fixed, but I can verify that this at least supressed the error message. This also does not specifically pertain to USB storage devices, but there is not a wiki page specifically for general USB controller usage and I didn't find it in order to create one just to add a single troubleshooting step.
