It actually is a HS device (it's a 4-port hub) - when booting the vendor supplied kernel (based off 2.6.32, i.e. pre -IR redesign), the device identifies as follows: Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB with the following boot messages: usb 1-2: new high speed USB device using ehci-omap and address 2 usb 1-2: New USB device found, idVendor=05e3, idProduct=0608 usb 1-2: New USB device strings: Mfr=0, Product=1, SerialNumber=0 usb 1-2: Product: USB2.0 Hub hub 1-2:1.0: USB hub found hub 1-2:1.0: 4 ports detected I've pasted the boot log for my kernel: http://pastie.org/1379102 And the boot log for the original kernel: http://pastie.org/1379100 Cheers, Tomasz
