Hello!

I have been attempting to get my RX888 working on Linux using libsddc. Everything built fine, I setup udev rules and downloaded the firmware from Github CI, ran
./libsddc/sddc_vhf_stream_test SDDC_FX3.img 3200000 10000 test.i16
The firmware was flashed successfully, but no samples were never actually pulled from the device.

frame_size = 138240, iso_packets_per_frame = 135
started streaming .. for 10000 ms ..

I then carried on to try #196, which either segfaults or returns the following :

normal FW binary executable image with checksum
FX3 bootloader version: 0x000000A9
writing image...
transfer execution to Program Entry at 0x40012a7c
ERROR - USB error LIBUSB_ERROR_ACCESS in find_usb_device at /home/alan/Downloads/rx888/ExtIO_sddc/Core/arch/linux/usb_device.c:462
ERROR - sddc_open() failed

Is this me doing something wrong? Both product IDs are set to be as chmod 666, and running as root does not help in any way. (And yes, this device works perfectly fine on HDSDR / Windows).

Otherwise, thanks for your work on this project!

Edit : I did try the firmware provided on Github, building it myself and extracting from the ExtIO. Same results in all cases.
