Hello All
How can I find out the firmware version of my RX888?
I found a Github about the RX888 firmware:
https://github.com/ik1xpv/ExtIO_sddc
73' Wolfgang
Why do you want to play with that?
As the links in there will give you the SDK but just for the USB FX3 chip.
As far as I understand is the firmware of the actual receiver loaded with the driver.
The firmware they describe just handles the USB.
Download latest Cypress EZ-USB FX3 SDK, if you make a mistake there, it will render the device useless.
I have downloaded the SDK and it's from Juli 2023, pretty sure the MK2 has this firmware as it's pretty new.
Could be wrong, but I would stay away from messing with this part of your device.
I have installed this ik1xpv/ExtIO_sddc before testing PhantomSDR-Plus on my archlinux.
I could use the RX888 MK2 with SDR++ via SoapySDR module then.
As read, SDR++ team has not publish a "driver" for this device, but it's old news.
Can I ask you the output of dmesg on your machines

It's when I start PhantomSDR-Plus, the first "Cypress" loads then the "sdr prototypes" takes over :

The device appear two times with 2 different idProduct ID, not sure it's normal
Note that on the raspi4 where ik1xpv/ExtIO_sddc does not compile (most likely because of aarch64) the dmesg is only :
[ 54.876930] usb 1-1.2: USB disconnect, device number 3

Ah that is what you mean. But it's normal, as the chip starts as USB2 device to be sure to be recognised.
Then after the firmware is loaded via the driver it switches to USB3.1 as far as I understand it.
I have read this somewhere about the working of this FX3 chip.
My output is the same.
Try connecting it, run dmesg, then run the driver...
See, RX888 connected:
[ 86.808196] usb 1-4: USB disconnect, device number 3
[ 96.154319] usb 1-4: new high-speed USB device number 6 using xhci_hcd

[ 96.302869] usb 1-4: SerialNumber: 0000000004BE
Now I run the driver/websdr:
[ 173.178125] usb 1-4: USB disconnect, device number 6
[ 173.459165] usb 2-4: new SuperSpeed USB device number 2 using xhci_hcd

[ 173.479930] usb 2-4: SerialNumber: 000900270A49140F
This happens as soon as this is running:
./rx888_stream/target/release/rx888_stream -f ./rx888_stream/SDDC_FX3.img -s 40000000 -g 60 -m low -r --pga
You can test yourself....and see it happening ;D
Ps. notice the serialnumber also changed!!!!
Ps2. see it like a usb-hub that brings the rest online on the USB-bus...the receiver itself.

I've not noted the switch from "high-speed USB device" to "SuperSpeed USB device"
Thx info concerning USB2 > USB3 behaviour from the chip

That is what it's doing, opening a new 'channel' to let the receiver work at 5GBPS, but maintains the normal 'channel', probably to control or send messages.
I think this is done to prevent USB3 compatibility problems, as not all USB3 ports always behave they way they should.
I have seen devices fail on USB3 ports many times. So starting in USB2 seems a good idea if you ask me.
Did you notice the serial-number of the FX3 chip is always the same?
But of the USB3 RX888 mode differs all the time.
Probably to let the 'driver' recognise it and send the bootloader/firmware.
I wonder if you can connect two RX888 to 1 machine as you can't supply a serial or device number, yet the USB2 serial mode is always the same.
Or maybe nobody ever thought anybody would?
