USB 2.0 Driver Limitations: 

1.After restarting Microsoft Windows XP operating system,
  USB device disappears or an exclamatory mark pops out (for example, USB HDD);
  please disconnect, and hot plug USB device again to get back normal function.   

2.While you are installing USB 2.0 driver under Windows XP,
  USB Keyboard and USB Mouse can't work out, but as the driver's installation is completed,
  they will resume working.
  Therefore, we strongly recommend you use PS2 Keyboard or PS2 Mouse while installing USB 2.0 driver. 

3.USB 2.0 port, under Microsoft operating systems, does neither support S1, S3, S4 (hibernate)
  Wake-Up nor S5 power-saving Sleeping modes while connecting any USB peripheries. 

4.If under DOS modes (DOS 6.x, Suspend To DOS 
  and Window Return), USB 2.0 port doesnˇ¦t support any USB peripheries.    

Currently, we are working on such limitations' solution.
As soon as the solution is done, the updated USB drive will be released to our website: www.pcchips.com.tw for your downloading.
