my usb meter only shows .00 but anything like my ftdi usb2serial even with led on shows .00 any and all devices that show .00 will not work; usb 1-1: new full-speed USB device number 9 using xhci-hcd [ 1744.708325] usb 1-1: device descriptor read/64, error -71 [ 1744.943858] usb 1-1: device descriptor read/64, error -71 [ 1745.180184] usb 1-1: new full-speed USB device number 10 using xhci-hcd [ 1745.307877] usb 1-1: device descriptor read/64, error -71 [ 1745.544013] usb 1-1: device descriptor read/64, error -71 [ 1745.657037] usb usb1-port1: attempt power cycle [ 1746.316452] usb 1-1: new full-speed USB device number 11 using xhci-hcd [ 1746.316715] usb 1-1: Device not responding to setup address.

if an idle device jumps between .00 and .01 50 percent of the time, then it will enumerate 50 percent of the time. If i simply add a small load to these devices with a resistor or a inline usb vol/amp meter then they work fine. im using the 5.7 patches ive tried the interconnect dts patches (dunno if that even makes sense) i know that enabling wifi in dts would break my right side usb port until recent patches. i may try with wifi and panel removed from dts and the min max regulator settings that come with those too and see if its any different.
