Ryzen 6000 (Rembrandt) USB4 support was generally underwhelming. Some of it may have been FP7 limitations, but some of it may have been lack of AMD board support (eg, the ZenBooks were supposed to have USB4 support, don't have a dGPU so not a board layout issue, but was held up by BIOS issues as well). Supply chain may have played a part as well - a lot of ODM/OEMs skipped it due to parts shortages (retimers or power delivery components?). These issues are still a problem for Ryzen 7000 mobile (Phoenix). For some more color, see this Framework update for example: https://community.frame.work/t/responded-amd-batch-1-guild/28693/123 https://community.frame.work/t/responded-amd-batch-1-guild/2... I did a lot of research on the G14, but actually I ended up not getting one and going for a 12th-gen Intel Framework instead: https://github.com/lhl/linuxlaptops/wiki/2022-Framework-Laptop-DIY-Edition-12th-Gen-Intel-Batch-1 https://github.com/lhl/linuxlaptops/wiki/2022-Framework-Lapt... I had a Batch 1 AMD motherboard pre-order but ended up cancelling for reasons, although I did end up deciding to get a 7940HS mini PC, which I'm running as my main desktop computer now and that I've documented here: https://github.com/lhl/linuxlaptops/wiki/Minisforum-UM790-Pro https://github.com/lhl/linuxlaptops/wiki/Minisforum-UM790-Pr... I have it connected w/ a LINKUP Thunderbolt 3 dock now and it seems fine, but I don't have auto-suspend on and don't suspend the device. Overall, I really like the UM790 device, the main issue w/ it (that thankfully has workarounds) is that OOTB it suffers from crashes/reboots - I was able to fix it by either disabling PSS in the BIOS or disabling C6 in runtime via MSR (after which it's stable). This is likely an AMD AGESA issue (this seems to be a recurring forever bug w/ Zen processors) and an upcoming BIOS update is promised to fix it.
