usb won't mount after reboot

Hello,

I Have an AC68U. Tonight I have plugged a usb key, installed entware, nano, all was fine.
But after rebooting my router, It doesn't seem to detect the key. The green usb logo is off in the web interface and fdisk - l doesn't list my key.

The last entries of the syslog are :
Jan 18 23:38:31 kernel: csw_retry 100
Jan 18 23:38:32 kernel: xhci_hcd 0000:00:0c.0: Failed to enable MSI-X
Jan 18 23:38:32 kernel: xhci_hcd 0000:00:0c.0: failed to allocate MSI entry
Jan 18...
