Re: [PLUG] Problem with USB Flash Disk
|
I've highluighted the difference below. Basically, your system is
running USB 1.1 not USB 2.0 - which is why I was able to use it on an
older computer as well.
It may be due to the device identifiers not being in the hotplug
mappings as someone olse suggested - but I think it's odd that it would
work in USB 1.1 mode but not USB 2.0 mode - as the identifiers aren't
changing between modes (as far as I could tell).
