Because the Reddit publish was once made, the problems had been extensively commented on through a couple of customers who skilled mentioned problems. Customers file that their USB connections will drop in a common means, inflicting keyboards, recording gadgets, and even VR headsets to lose connection.
The VR headsets are almost certainly the best way to breed the problem, as reported through the customers. A machine provided with a high-end GPU in response to a PCIe Gen4 interface along with a VR headset (which depends on high-power USB connections), can simply result in USB gadgets disconnect.
Workarounds had been urged, reminiscent of lowering the PCI Gen4 to Gen3 or through disabling the “C-States” in BIOS. Alternatively many customers have reported that the ones don’t resolve the issue, however somewhat cut back the frequency on which they’re skilled.
The basis reason for the intermittent USB connectivity problems is unknown. AMD is more likely to accumulate extra knowledge and expectantly supply a repair one day AGESA firmware.
AMD is acutely aware of stories {that a} small collection of customers are experiencing intermittent USB connectivity problems reported on 500 Collection chipsets. We have now been examining the foundation purpose and right now, we wish to request the group’s help with a small number of further {hardware} configurations. Over the following few days, some r/Amd customers is also contacted at once through an AMD consultant (u/AMDOfficial) by way of Reddit’s PM machine with a request for more info.
This request might come with detailed {hardware} configurations, steps to breed the problem, particular logs, and different machine knowledge pertinent to verifying our building efforts. We can supply an replace when we have now extra main points to proportion. Shoppers going through problems are all the time inspired to lift an On-line Provider Request with AMD buyer make stronger; this permits us to search out correlations and examine notes throughout make stronger claims.

AMD B550 motherboard chipset has won a large improve at the I/O entrance. Suitable CPUs can now make stronger as much as 4 USB 10 Gbps ports with the addition of 2x 10Gbps, 2x 5Gbps, and 6x 0.480Gbps ports treated through the chipset. The GPU and garage gadgets can now get pleasure from the PCIe Gen4 interface connected to the CPU, whilst the chipset is now the usage of PCI Gen3. That is an improve over the B450 chipset on each fronts.
Some answer here
Observation: In my finish it was once purpose through the 4 phases usb slot…. most likely agesa 1.2.0.3a will repair the problem. I forestall the usage of the port now…
