Hi, |
| 2 |
|
| 3 |
I have bought an ESP8266 Lua NodeMCU board, which has |
| 4 |
an FTDI-like chip on board to map USB to serial and |
| 5 |
vice versa. It is an CH340 one. |
| 6 |
There is an according module in the driver (compiled |
| 7 |
and - to get shure - loaded by hand). |
| 8 |
|
| 9 |
When I connect the ESP8266 board to my Gentoo PC |
| 10 |
nothing happens (dmesg shows nothing). |
| 11 |
When pressing RST on the board, I see this sometimes: |
| 12 |
|
| 13 |
[ 4340.105221] usb 7-4: new full-speed USB device number 9 using ohci-pci |
| 14 |
[ 4340.630234] usb 7-4: device not accepting address 9, error -62 |
| 15 |
|
| 16 |
(both lines are printed right after another - no delay...) |
| 17 |
|
| 18 |
or this: |

| 32 |
|
| 33 |
there is no new device under /dev/. |
| 34 |
|
| 35 |
Do I miss something seriously important here related to using the |
| 36 |
CH340 driver...or is this board simply demaged ??? |
| 37 |
|
| 38 |
Thank you very much in advance for any help! |
