### ⭐ Fails to boot due to USB Device overcurrent issue - apparently it’s a common issue
*by T***L on January 15, 2026*

This motherboard will not boot due to “USB Device in Overcurrent State Detected” error at boot. It just keeps cycling. I tried removing all USB connectors and devices, but the issue persists. I am really disappointed with this ASUS mobo. ASUS tech help team, there are literally thousands of comments on Google/reddit, can you guys comment and may be fix this issue with this mobo?
