[Ham-Computers] PCMCIA vs Cardbus Device

[Jim Hill]

Do cardbus adapters always work when plugged into a PCMCIA  port?

I just purchased a wireless adapter, which was advertized as a PCMCIA 
device, but the label on the device says 54mbps wireless card 
(Cardbus).  It works ok.  More recently, I purchased a D-Link USB 2.0 
adapter.  I overlooked the word cardbus when I purchased it, and when 
I received it phoned the manufacturer to see if it would work.  The 
sales rep said yes, but first asked for the model number.  It works 
with an optical mouse, but have not tried anything else.

Are the two identical, or is the cardbus better in some manner?

Thanks, Jim
