Occasionally USB and Bluetooth gadgets pause for about ten seconds.
Good morning. I connect my G502 Hero mouse via USB-C Type-A, use a Type-A receiver for the G515 keyboard, another receiver for the G522, and have one USB-A port that stays plugged in even when not in use. I also have a Bluetooth device and prefer WiFi over LAN. Occasionally, all my devices stop working briefly—around ten seconds at a time, including wireless ones. The Bluetooth link to a Google Nest speaker (which works as a speaker without headphones) drops. This issue started after I got the G522, so it might be a system overload. All cables go straight to the motherboard. One headphone receiver is plugged into a USB 3 SS10 port (green port, likely correct per manual), but I used it on BIOS mode because no other Type-A ports were available. The CPU cooler screen turns black, RGB fans reset to default at startup, then briefly return to their setting, and the Bluetooth reconnects. This happened right after I sent the email. My processor is a 9600X. This information comes from my recent support request; it’s a B650 TUF Plus with Wi-Fi.
The most probable issue is having too many USB devices competing for the B650’s shared bandwidth. All devices freezing together points to a USB root hub or controller reset. This isn’t just one port failing; high bandwidth or fast polling devices such as premium gaming mice can exacerbate the problem. Try reducing the polling rate on your mouse if you’re running it at maximum speed. Another possibility is that multiple programs using sensor data simultaneously may overload the USB controller driver, triggering a firmware reset. Your RGB reverting to default and the display going black suggests the USB HID interface reset during polling. If several hardware monitoring tools are active, consider disabling some to simplify usage. Running Icue for fans and RGB while opening a sensor app can cause the display to freeze. Too many devices operating on 2.4GHz can lead to packet loss, but this usually results in RGB cutting out rather than full system hangs. If you need high polling rates, consider upgrading to a new motherboard with a better USB controller and bandwidth.
Avoid connecting receivers through the BIOS-flashback port—they’re usually only for flashing and may act differently. Consider using a powered USB hub to prevent wireless dongles from competing for bandwidth or power on the same controller. In BIOS, verify whether USB selective suspend or ErP is active and attempt to disable it. Ensure chipset USB drivers are fully updated, as this can resolve intermittent disconnections. Since the issue began after installing the G522, it may be due to additional load or traffic causing a reset. Distributing dongles across different controllers by adjusting I/O vs front panel headers, or using a PCIe USB card, could also help.
Discussing wireless and 2.4 would also explain why your Wi-Fi feels so weak lately. It seems the new headset might be the cause. Regarding ports, using them directly on your case is better than relying on the motherboard. Switching to a wired keyboard could also help.
Probably due to interference from many 2.4 devices, which leads to packet loss. This happens more when there are numerous 2.4GHz devices, especially in crowded areas like large apartment buildings. In such settings, the spectrum can become jammed. I'm in an apartment complex with around 70 other units, not the biggest one, but I still feel the saturation and have to disable it on my main PC to prevent issues.
Your Wi-Fi operates on the 5 GHz frequency band. This affects speed and range, so consider it when choosing devices or locations.
Because it isn’t in the BIOS port, the next step would be to examine the BIOS settings USB selective suspend / ErP and refresh the chipset USB drivers. Additionally, if feasible, distribute the dongles among various USB controllers rear I/O, front panel, or even a PCIe USB card to prevent them from competing on the same controller.
