GCFFlasher_internal causes USB serial device to be unregistered and fails

[mattiasflodin]

I connect ConBee stick and see this in kernel log:

I run GCFFlasher_internal -l:

GCFFlasher V3_17 (c) dresden elektronik ingenieurtechnik gmbh
Path             | Vendor | Product | Serial     | Type
-----------------+--------+---------+------------+-------
/dev/ttyUSB0     | 0x0403 | 0x6015  | DJ00QDS1   | ConBee 

I try to update firmware by running

GCFFlasher_internal -t 60 -d /dev/ttyUSB0 -f deCONZ_Rpi_0x26400500.bin.GCF -sn DJ00QDS1 -x 3

GCFFlasher_internal outputs this in a loop for 60 seconds then gives up:

10:06:21:928 using firmware file: deCONZ_Rpi_0x26400500.bin.GCF 
10:06:21:975 ls dev: /dev/ttyACM0 (0x0658/0x0200) sn:

At the same time, I see this in kernel log:

[ 4788.425720] usbserial: USB Serial deregistering driver FTDI USB Serial Device
[ 4788.426059] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0

[ 4788.451925] usbcore: deregistering interface driver usbserial_generic

The /dev/ttyUSB0 device is now gone from the file system. It appears that running GCFFlasher_internal immediately causes the /dev/ttyUSB0 device to unregister and then it can't find it.

How do I make this work so I can update firmware on my ConBee stick?

Some solution ideas:

• discard the -sn parameter; -d should be enough or use -d with the /dev/serial/by-id path
• during the update process disconnect and connect the conbee again
• try another GCFFlasher version (e.g. GCFFlasher 4 from this repository)
• try the update on another system (I had a similiar error and after installing a new raspian os on my sd card it worked also with GCFFlasher 3.17)

I discarded the -sn parameter (this was something I added later when just -d didn't work) and then tried to unplug and reconnect the conbee during update. That gave me another behavior that seems to go further but it still loops and eventually fails.

After timeout it ends with

Update: I tried the v4.0.0-beta release from this repository and it core dumps when I run the -l flag to list devices, but it actually succeeded in flashing new firmware. Thanks!

Closing this for now, the latest GCFFlasher 4.x versions support all ConBee and RaspBee devices, and not crash ;)
