Hey guys. I am looking to buy a serial to USB adaptor to connect my GPS receiver to my laptop. I have a new PB with the 2.0 USB ports. Will it make any difference in speed of data transfer whether I buy an adaptor with the USB 1.1 vs 2.0? The 2.0 ones are more expensive and I was unsure whether the serial connector would be the rate limiting step in the transfer, thereby negating the benefit of the 2.0. Thanks.

The short answer is yes, it will be slower. USB 2.0 is considerably faster than USB 1.0. But the two are compatible. Anytime you introduce any component in a situation that is not as fast as the rest, you will slow down the entire transfer of information.
