Is there a way to know which ports handle USB2.0 (EHCI), and devices wattage (like with the usbdevs command) ? Before usb2, I had the following kernel output : usb0: <UHCI (generic) USB controller> on uhci0 usb0: USB revision 1.0 usb1: <UHCI (generic) USB controller> on uhci1 usb1: USB revision 1.0 usb2: <UHCI (generic) USB controller> on uhci2 usb2: USB revision 1.0 usb3: EHCI version 1.0 usb3: companion controllers, 2 ports each: usb0 usb1 usb2 usb3: <EHCI (generic) USB 2.0 controller> on ehci0 usb3: USB revision 2.0 The line "companion controllers, 2 ports each: usb0 usb1 usb2" was quite useful. Any way, I'm running GIANT-free now :) Great work ! -- Olivier Smedts _ ASCII ribbon campaign ( ) e-mail: olivier@gid0.org - against HTML email & vCards X www: http://www.gid0.org - against proprietary attachments / \ "Il y a seulement 10 sortes de gens dans le monde : ceux qui comprennent le binaire, et ceux qui ne le comprennent pas."
