From: Touillaud Nicolas <Nicolas.Touillaud_at_fr.thalesgroup.com>
Date: Thu, 19 Feb 2004 10:04:04 +0100 a possible reason for full speed: some USB2 adaptors can't handle full and high speed at the same time, i.e. the slower usb device atached set the maximum speed. the problem is hardware related... A friend of mine had this problem using the built-in usb controler of its sony vaio, he just unplugged the mouse, re-plug it's 2.0 external drive and shazzam ! High speed !
