if that can help, we had an user on http://www.linuxmao.org with an EIE PRO. Here you have his lsusb -v :
Bus 001 Device 006: ID 09e8:0010 AKAI Professional M.I. Corp. Couldn't open device, some information will be missing Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 255 Vendor Specific Class bDeviceSubClass 255 Vendor Specific Subclass bDeviceProtocol 255 Vendor Specific Protocol
According to the tech specs, this should be a USB hub, but it isn't. Or is this just one of the sub-devices? What does 'lsusb -t' say, and does Linux see something like a mouse or mass storage device when connected to one of the hub ports?

Hi Daniel and all,
An linuxmao.org user gave answers to these questions today. Here you go:

I'll be asking him to try connecting a mouse to one of the hub port and to get a dmesg from there.
Hope that can help in any way. If you would need some more information, please let me know.
