I studied the USB transfers and I think the 805 is very similar to the existing drivers for wouxun radios.
Here is how I think you need to interpret the data transfers Using your example -- I have broken down the data into pieces The blue is likely the header which likely is the broken down into a start byte (57) the start address (0010) and then the number of bytes to transfer (40hex = 64bytes) then comes the 64 bytes of data . for this example you are starting at address 0010 and getting data for channels 1,2,3,4 Each 16 bytes of the data applies to a single channel broken down as follows Orange ( 4 bytes) = RX Freq Green (4bytes) = Tx Freq Purple (2bytes) = Rx Tone Light Orange (2bytes) = Tx Tone then 4 bytes of channel specific settings.that you will need to decode I think the mistake you are making is that you are assuming each data transfer line is a specific channel when in fact it is simply 64 bytes of data and what is stored in the data is dependent on the memory map location and address being transferred. For this region, each 64 bytes is 4 channels worth of information. I am not sure if this data is encoded or not - Likely not. You could confirm by checking the frequencies stored in the channels
based on this data I think you have the following Ch1 - 50622546 Rx Freq = 462.56250 MHz : little endian representation of the freq*100000 Ch2 - 50872546 Rx Freq = 462.5875 Mhz Ch3 - 50122646 Rx Freq = 462.6125 Mhz Ch4 - 50372646 Rz Freq = 462.6375 Mhz
also for Ch 3 you have 9E02 for the Rx tone which is little endian representation for 029E when converted to dec = 670. So it matches your tone setting of 67 when divided by 10.
If these are the freqs stored in the radio channels then the data transfers are not encrypted and you can accept the bytes as is. You would just need to read the complete memory and store the data in the proper addresses.to build the radio image. Take a look at the 816 driver and see how to do that. I think your captures are showing differences that are exactly as I would expect them to show.

Hello,
I'd love some help creating a driver for the Wouxun KG-805g radio ( https://chirpmyradio.com/issues/11214). I've performed captures of all the settings, they can be found here: https://github.com/mildebrandt/kg805g
Looking at the trace files, I'm a little confused about the memory layout. I changed the R-CTC setting from "off" to "67.0" on channels 3, 4, and 13. Here are the differences:

My uninformed thought would be that I'd see the bytes change in the same position for the same setting on each channel, but they seem to be all over the place.
What does this mean for me trying to lay out the memory? Am I being fooled by the trace output...and it's being recorded out of sequence? I wouldn't think so since the ordering looks to be stable per channel.
I'll describe my setup in case there's something weird there. I have an Intel Macbook Pro with Fedora Linux installed. In Fedora, I have a qemu Windows 10 machine that's running the Wouxun software. I'm running tshark on the Linux side to capture the USB traffic.
Any pointers would be appreciated. I'm pretty far over my head, but hopefully I can help get this radio into chirp. :)
