I have installed the latest version of Audacity 2.x software download onto W7 32bit Home premium. Seems successful but when plugging in turntable it says USB device is not recognised and leaves unknown device saying no driver for this device. Looked for software update but none to be found by any means and Windows update.
Maybe something here:
