Re: [BUG] USB_PERSIST

["Raymano Garibaldi" <raymano@faunos.com>]

The last time I tried this and it worked was 2.6.21. Below is a
portion of the kernel log file where I had a USB storage device
attached to the computer, then suspended the computer, while computer
was suspended detached and reattached the USB storage device, and
resumed the computer.
