I have the dreaded USB drive not recognized after upgrading the switch from IOS 12 to IOS 15. Since I was able to reproduce I open a TAC case and after 1 month I am told to get a cisco certified USB drive or stick.
Why doesn't CICSO fix this bug in the IOS. This seems like a small thing to correct. As a consumer, I'm being told to go "find" or "purchase" a CISCO certified USB drive (stick). In this day and age this is absurd.
Hey CISCO own up to your bug and fix it. Stop shoving the problem back on the customer.
