Suunto Zoop download issue

[stuaburt]

Having upgraded my tablet to Windows 11 ARM64 (from Android) I decided to install Diving Log 6.0 to test for this years dive trip.

The dive computer is Suunto Zoop (not Novo)
I am using a USB interface from smartinterface.de and have loaded the latest FTDI signed ARM64 drivers. The interface shows as a serial port on COM3.
The dive download fails with error ERROR: DC_STATUS_PROTOCOL after starting communication.
Logfile is attached.
I have downloaded the latest libdivecomputer version from the Diving Log website.
The dive computer has plenty of battery life.

Trying Suunto SDM3.1.0 shows some communication with the Zoop (serial number) but does not download dives. There are 46 dives present on the Zoop.

Is there anything else I could try please? Everything works with my Windows 10 laptop but it's too large to take on holiday.

Many thanks.

Hi

Difficult to say. What I can see in the error log is, that the communication starts and some data is exchanged:

But the data seems to be wrong, so I guess it is a driver issue. You can ask Jef Driesen if he can see something in the transferred data: https://www.libdivecomputer.org/contact.html

Thanks for getting back. I'll try Jef but plan B is to use my Android phone which seems to download well with a USB OTG adapter.

Is this issue resolved? I read your emails in the libdc newsgroup and it looks like it worked using a powered hub, but there seem to be another issue with Diving Log?
