  I happen to have one of those Alcor hubs in a box: it a USB 1.1 
device, and it is crap. A really cheap discount chipset often included 
in many device or computer cases to provide a extra usb exposed SD card 
etc ports on the motherboard.  Crap.  I say toss it.

$ lsusb | grep Alcor
Bus 004 Device 004: ID 058f:9254 Alcor Micro Corp. Hub
$ lsusb -vd 058f:9254 |grep USB
Couldn't open device, some information will be missing
  bcdUSB               1.10

As opposed to a desktop/laptop drive IDE to USB adapter I use:

$ lsusb -vd 14cd:6600 |grep USB
Couldn't open device, some information will be missing
Bus 001 Device 006: ID 14cd:6600 Super Top USB 2.0 IDE DEVICE
   bcdUSB               2.00
   idProduct          0x6600 USB 2.0 IDE DEVICE
