Fixing USB bus
After booting for the first time, it is likely that messages such as this will flood your serial console:
[ 453.142468] usb 2-1: new high-speed USB device number 97 using ci_hdrc [ 453.222475] hub 2-0:1.0: unable to enumerate USB device on port 1 [ 453.662416] usb 2-1: new high-speed USB device number 98 using ci_hdrc [ 453.852421] hub 2-0:1.0: unable to enumerate USB device on port 1 [ 454.292397] usb 2-1: new high-speed USB device number 100 using ci_hdrc [ 454.382381] hub 2-0:1.0: unable to enumerate USB device on port 1 [ 454.822327] usb 2-1: new high-speed USB device number 101 using ci_hdrc [ 455.022335] hub 2-0:1.0: unable to enumerate USB device on port 1 [ 455.462285] usb 2-1: new high-speed USB device number 103 using ci_hdrc [ 455.672275] hub 2-0:1.0: unable to enumerate USB device on port 1 [ 456.112232] usb 2-1: new high-speed USB device number 105 using ci_hdrc [ 456.192244] hub 2-0:1.0: unable to enumerate USB device on port 1
This command can be run after a cold boot and it will fix the usb bus:
i2cset -y 1 0x08 0x66 0x48
After this command runs, the following data will print to the console:
[ 456.798644] hub 2-1:1.0: USB hub found [ 456.802728] hub 2-1:1.0: 4 ports detected [ 457.102481] usb 2-1.2: new high-speed USB device number 107 using ci_hdrc [ 457.312481] usb 2-1.3: new high-speed USB device number 108 using ci_hdrc [ 457.447255] hub 2-1.3:1.0: USB hub found [ 457.451603] hub 2-1.3:1.0: 4 ports detected
