I have problems with AiDisk feature. I configured it once, detected correctly the USB devices (two flash drives), but can't access the disks from ftp. So, I made a factory reset and then load the settings from file and now, I got the message "No USB disk detected" when I click on USB Application>AiDisk, even the drive is recognized when I hover the mouse pointer on the top right, on USB icon. The same problem with both flash drives, using both USB ports from router, one at a time. Anyone know how to solve this?
