can detect 6022 but ok button is disabled

hi, can detect 6022 but ok button is disabled

[ruckusman]

I've got this same issue with MacOS Ventura - for me the detected devices comes up empty, then when I use the dropdown menu it displays the 6022BL but a message flashes past mostly too quickly to read, about unable to upload firmware.

The scope and logic analyser functions do still work with pulseview however.

It's never been great at connecting automatically, with either program, but I've lost OpenHantek altogether.

OK, so I just got it to connect by being stubborn and attempting to connect three times in a row;
I've repeated this process twice to confirm, leaving the scope plugged in in key, because each time it's unplugged it resets to the first error, which means it again requires two unsuccessful attempts to connect for the third so succeed.

1. opening OpenHantek once, choosing the 6022BL from the dropdown menu gives the following error (it flashes past quite quickly) UploadFirmware; libusb_claim_interface() failed: LIBUSB_ERROR_NOT_FOUND
   Keep the scope connected, close the Openhantek start dialog.

first-attempt-1.mov

2. Opening Openhantek a second time, the device won't be automatically detected as per previous attempt, however it will again be in the dropdown menu selection items - the error this time is different:
   "Connection failed!
   Entity not found (020:005)"

second-attempt-1.mov

3. Success on the third try and each time thereafter as long as the scope is left plugged in.

Hope this helps

Following the advice here #364 (comment)

I've got the output from running /Applications/OpenHantek.app/Contents/MacOS/OpenHantek --verbose 4 three times in a row, the third time is obviously successful in the firmware upload and connection between OpenHantek and the scope

First attempt:

FindDevices::updateDeviceList()
repeats until the splash screen is closed

Second attempt:

Third time success:

Hope this helps, if there's anything else I can do, just holler
