I tested usb on DM6446, montavista kernel 2.6.10 patchlevel 45 And every usb peripheral i plug led to the same error: # usb 1-1: new high speed USB device using musb_hdrc and address 4 usb 1-1: device descriptor read/64, error -71 usb 1-1: device descriptor read/64, error -71 usb 1-1: new high speed USB device using musb_hdrc and address 5 usb 1-1: device descriptor read/64, error -71 usb 1-1: device descriptor read/64, error -71
Does anyone know how to solve that ?
