I subscribe to a monthly electronic surprise box <https://www.instructables.com/HackerBox-0061-Props/>. This month's surprise is a Propeller 2 8x32bit processor on a circuit board that connects to a computer with USB. The circuit board and chip are RT232RL Serial USB Interface.
The FT232RL chip by ftdichip.com does not identify itself to the usb hubs. Tried many. Tried different cables. Loaded the suggested driver. It's transmit and receive lights flash when plugged in. The dmesg output when device is plugged into a 3.0 port is: [Thu Dec 10 21:32:13 2020] usb 3-1: new full-speed USB device number 14 using xhci_hcd [Thu Dec 10 21:32:13 2020] usb 3-1: device descriptor read/64, error -71 [Thu Dec 10 21:32:13 2020] usb 3-1: device descriptor read/64, error -71 [Thu Dec 10 21:32:14 2020] usb 3-1: new full-speed USB device number 15 using xhci_hcd [Thu Dec 10 21:32:14 2020] usb 3-1: device descriptor read/64, error -71 [Thu Dec 10 21:32:14 2020] usb 3-1: device descriptor read/64, error -71 [Thu Dec 10 21:32:14 2020] usb usb3-port1: attempt power cycle [Thu Dec 10 21:32:15 2020] usb 3-1: new full-speed USB device number 16 using xhci_hcd [Thu Dec 10 21:32:15 2020] usb 3-1: Device not responding to setup address.
