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
