You say the pen drive and the card reader end up running at full speed?
Do you have _any_ device that will run at high speed on that computer?
If not, then most likely the USB hardware on the computer isn't working
right.
Conversely, if you plug the Genesys hub into other computers, does it
then run at high speed? If not, then most likely the hub isn't working
right.

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.

Try what I said above -- mixing and matching components to figure out
which ones aren't working.
