I have a Compaq cq5115uk dual booted Windows Vista & Ubuntu 14.04 and a HP Laserjet 1020 printer. Under Windows the printer only works if I disable the usb 2.0 devices in Windows device manager leaving only the usb 1.1 devices. Under Ubuntu the printer doesn't work. I'm guessing the problem is the same as Windows, so I'd like to know how to disable usb 2.0 under Ubuntu. Thanks

How to disable usb 2.0 under Ubuntu?

Try with one feature in the kernel, the ability to bind and unbind drivers from devices manually from user space.

In the sysfs tree, every driver now has bind and unbind files associated with it.

In order to unbind a device from a driver, simply write the bus id of the device to the unbind file.
