This time I plugged the keyboard into the hub and got a stream of uhub_reattach_port: giving up port reset - device vanished which didn't stop when the keyboard was removed. If the keyboard is moved to the Pi's internal USB connectors the keyboard is recognized and works, but the once-per-second "...device vanished" messages continue. Attempts to repeat this behavior were frustrating. After a few iterations the error message was triggered by plugging in an FTDI usb-serial adapter, but the messages stopped when it was unplugged. The hub is Bus /dev/usb Device /dev/ugen1.4: ID 05e3:0610 Genesys Logic, Inc. 4-port hub The disk adapter is Bus /dev/usb Device /dev/ugen1.5: ID 152d:1561 JMicron Technology Corp. / JMicron USA Technology Corp. JMS561U two ports SATA 6Gb/s bridge Are either of these known troublmakers? Thanks for reading! bob prohaska
