The Hub in question is internal to the RPi3B. It also shows up on my RPi3B with no external hubs involved. (But I've never had the failure mode occur.) Manufacturer=20 Product U-Boot Root Hub SerialNumber=20 bind node usb1@1 It is a hub with 5 ports, one associated with the EtherNet port and 4 for plugging things in. Or, that is my understanding. I've little clue what would interfere with its operation in this specific way. > is (sometimes) underpowered ( 1,5MB), has to be 480MB instead.. > While even a broken USB cable can of course trigger this issue , > I guess this is not the first time that an USB hub-port fails by = underpower on those dev boards or elsewhere, > So `ring ring` HPS,... how to force inject more power to port1 in = /common/usb_hub.c ? :-) Ha Ha=20 =3D=3D=3D Mark Millard marklmi at yahoo.com
