Subject: [gentoo-user] [OT?]: CH340 working/not working with ESP286 Node MCU
Date: Fri, 8 Jul 2016 05:22:02 +0200 [thread overview]
Message-ID: <20160708032202.GA4623@solfire> (raw)
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
