Sorry, terminology problem. Pen and card reader was running HIGHSPEED (usb2.0, which is the full speed of the device, which isn't "full speed" by USB talk), corectly. Hub does run at usb1.1, or "full speed", while it should be capable of "high speed". > Conversely, if you plug the Genesys hub into other computers, does it > then run at high speed?

Well I do not have plenty of computers around (at least not with USB2.0 plugs, as I have plenty of junk anyway), the one which possess USB2.0 but is a very similar chipset, and it sees the hub "full speed" (usb1.1) as well. That's why I asked about whether anyone met this chipset and whether it ran high speed anywhere at all. > > Feb 7 15:52:33 narya kernel: [827442.494242] ehci_hcd 0000:00:1d.7: port > > 4 full speed --> companion > > Here you see that the EHCI hardware on the computer thinks it has > detected that the Genesys hub doesn't want to run at high speed.

So the hub states that it's a high-speed device, and the USB subsystem seems to be aware of that fact. I'll try to talk to Genesys about this, since I'm out of permutations available on my present hardware pool. It's pretty hard to claim faulty hardware usb-wise since it's a mistery to hardware shops... they probably couldn't tell 1.1 from 2.0 even if forced by firearms.
