I have the same issue… I installed the new firmware from two different intel computers, but still having the problem … I have the v29952 which is the last version on it but still not working …
Hi Agus
Problems with intermittent connection of USB devices on AMD Ryzen systems are a legacy chipset issue induced by the host computer.
If issues persist with a K2 that has V2.5.0 firmware installed, it may be possible to resolve this symptom by changing the GPU PCIe mode in the system BIOS, from ‘Gen4/Auto’ to ‘Gen 2’.#
Alternatively, ensure the CPU’s firmware is up to date. If the problem persists with the latest system update, switch to host with an improved chipset.
