The link is an article on the history of electronic keyers.? It is quite lengthy but if you read it you will learn a lot.? It seems that with each major product introduction a new subtle or not so subtle difference in timing was also introduced.
?
From the article, the major difference between mode A and B is that mode B polls the opposite paddle for a pressed state during the sending of the element and the following element space.? Whereas mode A polls the opposite paddle for a changed of state from not pressed to pressed.? This difference is what prevents mode A from not sending an extra un-keyed element that turns letter K's into C's.
?
The current Zbitx code for mode A polls for a pressed state of the opposite paddle same as mode B during the carrier on? period and does not poll at all during the element carrier off period.?? It would be interesting if some of the users who say it works or say it doesn't work would report what mode they use.? I can't see that a Mode A user would have a good time at all with it working mostly as mode B.
?
The mode B code still has the bug I pointed out twice that will change a DIT paddle contact to sending an unwanted DAH if the paddle contract is made during the carrier off period.

Re: Does sequence of updates matter?
Okay, so I replaced the OTG adapter and now keyboard and mouse are working as they should. I used this one
I am back to a fully working radio again :)
I remain watching the thread on CW updates with keen interest as mine is behaving exactly like AE5X's.

Re: Zbitx power cord connector
This is unfortunate. We actually ordered a die to be made for this connector!
My plug failed on like the third start. I ordered this and they transmit power fine (one to replace the failed plug and one for the power supply), but they’re slightly longer. A very small o-ring would take up the space if that’s a concern.?

Re: Waiting for the zBitx to start…
In addition to the uSD card, you need to buy a uSD card reader, which can be read via USB and written with a writing program.
Make sure that the USB can be connected to both the PC and zbitx. To the PC when you download the Image, to zbitx when you want to make a backup.
Since the published Image is in .zip format, you have to unpack it first, which is 32GB in size here.
It may happen that during production, the 32 GB SD card cannot be written to, because the new card is a few bytes smaller than the Image.
That is why you may have to buy a 64 GB card.
If the creator of the Image is more skilled, he will remove the empty part of the card using the shrink method, and the Image could be much smaller.
It is advisable to buy a good quality uSD card, which can also be used for Backup.
Don't worry, if you insert a 64GB uSD into the device, you can copy it to a smaller size than Backup using Raspberry->Menu->Accessories->SD Card Copier.
It is advisable to make a Backup, if you have successfully set the .ini files, you can use the Backup to restore in case of an error.

zBITx Power Plug Intermittant
The only thing Which jumped out at me was a highly intermittent power cable between the batteries and the unit which was supplied by HF Signals. Rotate the connector or barely touch the cable and it would recycle power. I replaced it with a new 5.5mm outer barrel and 2.1mm inner barrel cable and it now works fine and is very stable.
?
The new cable has a full 360 degree "tube/barrel" to make GOOD contact with the center pin in the female connector,?the original does not....take a look at it.?
?
Great Little Radio?

Is there a way to export the FT8 QSO’s in ADIF format from the SQLite DB?? Or are they also saved in ADIF format in a separate file? ?
My unit has not shipped yet. So I can’t poke around the file system yet.?
I like to log all my QSO’s in central log on my shack computer.?
Thank you

Re: Waiting for the zBitx to start…
Unfortunately, not yet. I'll follow Jeff's advice tomorrow and buy an SD card and research how to transfer the data to the SD card via PC. I haven't done anything like that before. I'm still clueless and hope it will work. I'm not a computer expert.

? On the sBITX, the shut down button in JJ's sbitx code is in menu 2. There is no need to open the toolbox.
? On the zBITX, unless you have an external monitor, there is no way to get to a Linux window. The zBitx display is controlled by the Pi Pico run by the zBitx app on the Pi Zero. A useful shut down function would have to be part of the zbitx code.

I updated my Zbitx yesterday (Wednesday) to 3.051 and 1.06. Yes it fixed a couple issues but CW remained unusable. So today (Thursday) I decided to update again, thinking I might have gotten an earlier Raspberry pi copy.
Now I have bricked the radio... No boot up of the Pi ( screen is ok). With an external monitor the Pi doesn't go past the first steps of booting, freezes and ignores keyboard and mouse.

It stops at the following:

? Line 4527: ?modem poll is only being called every 20th tick
Modem_poll , then calls cw_poll -but this cannot happen any faster than every 20th tick with the current code
It is actually CW_POLL that really causes transmit to occur. But this cannot start any faster than every 20th tick because of the way the routines ?are being called.
It is easy enough to prove us wrong. Simply change the calls to modem pole to occur every fourth tick (instead of every 20th tick ) and if it doesn’t get a lot better than we’re wrong.
Wishing you the best!

The issue is most likely caused by poling the state of the key 96000 times a second and only acting upon it in modem poll 10 times per second. The solution in the 64-bit branch was to adjust modem_poll to check multiple times in each call.? The transition states are being made but not acted upon.

I do not yet have my zBitx setup, so I can not test using a macro to call JJ's shutdown script in the toolbox.? The macro button, like the logging function buttons, could be available on all screens.
