Hi, I have bought an ESP8266 Lua NodeMCU board, which has an FTDI-like chip on board to map USB to serial and vice versa. It is an CH340 one. There is an according module in the driver (compiled and - to get shure - loaded by hand).
When I connect the ESP8266 board to my Gentoo PC nothing happens (dmesg shows nothing). When pressing RST on the board, I see this sometimes: [ 4340.105221] usb 7-4: new full-speed USB device number 9 using ohci-pci [ 4340.630234] usb 7-4: device not accepting address 9, error -62 (both lines are printed right after another - no delay...) or this: [ 4473.567739] usb 7-4: new full-speed USB device number 11 using ohci-pci [ 4473.712306] usb 7-4: New USB device found, idVendor=1a86, idProduct=7523 [ 4473.712316] usb 7-4: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [ 4473.712321] usb 7-4: Product: USB2.0-Serial [ 4473.763259] usbcore: registered new interface driver ch341 [ 4473.763278] usbserial: USB Serial support registered for ch341-uart [ 4473.763295] ch341 7-4:1.0: ch341-uart converter detected [ 4473.786463] usb 7-4: ch341-uart converter now attached to ttyUSB1 [ 4473.888987] usb 7-4: USB disconnect, device number 11 [ 4473.889485] ch341-uart ttyUSB1: ch341-uart converter now disconnected from ttyUSB1 [ 4473.889511] ch341 7-4:1.0: device disconnected [ 4474.292773] usb 7-4: new full-speed USB device number 12 using ohci-pci there is no new device under /dev/. Do I miss something seriously important here related to using the CH340 driver...or is this board simply demaged ??? Thank you very much in advance for any help! Best regards, Meino
