The past has shown that USB devices not always work on all USB ports and both sides don't like any cable. So below are some effects that indicate a possible communication problem due to incompatibilities.

• The device isn't detected by the OS at all.
  
• The device is detected but malfunctional (driver installation is rejected / VID/PID=0x0000).
  
• The device is working, communication sometimes fail on various reasons.
  

If one of the effects occurs, we always prefer the following steps:

• Using other USB ports often helps (mainly by using a port on the backside instead one in the front panel).
  
• Another USB cable may help too. Especially when transfering with high bandwidth.
  
• Sometimes plugging an USB HUB between host and device can help. Active HUB's are better than passive ones.
  
• If none of the above helps, a PCI/USB adaptor has a good chance to bring the device to work.
