#922 --port hangs on TS-7800

[Thor-Inge]

I am having trouble using --port on my TS-7800 from Technologic systems.
Autodetect works fine like:
./gphoto2 --capture-image-and-download --force-overwrite
but this hangs:
./gphoto2 --capture-image-and-download --debug --debug-logfile=debug.txt --force-overwrite --port=usb:002,002

List of ports reports:
./gphoto2 --list-ports
Devices found: 10
Path Description
--------------------------------------------------------------
ptpip: PTP/IP Connection

serial:/dev/ttyS4 Serial Port 4
serial:/dev/ttyS5 Serial Port 5

I tried this on Ubuntu, and no problems there, but on the TS-7800 it hangs here:

I also tried with a Canon 40D, and the same problem there.
