I have an Netgear r8000 that was previously serving as a secondary AP and backup server with DD-WRT. I've since reinstalled with OpenWRT 18.06 and have been having trouble reproducing my setup, specifically because my external USB3 hard disk does not make a /dev/sda entry when turned on. I'm assuming this sequence in dmesg is the reason:
[ 335.040264] usb 4-1: new SuperSpeed USB device number 3 using xhci-hcd [ 335.072566] xhci-hcd 18023000.xhci: ERROR: unexpected command completion code 0x11. [ 335.120442] uas: probe of 4-1:1.0 failed with error -12
Any suggestions as to what I might try to resolve this?
