Problem with spanning tree detection

I am using 3 new usb2 /10/100 adapters. Each one disables it’s switch ports over time. Seems to cause a cisco switch to shut down ports due to a spanning-tree algorithm detection. Any thoughts?

Hello Dave,

Thank you for your message.

I would note that the USB2-E100, as well as our other network adapters, aren’t really meant to take the place of high-end network adapters and are mostly for general consumer usage. They aren’t really intended for long-term high-traffic extended use.

What sort of traffic is being routed over the USB2-E100 devices you’re using?
