Connexting Desktop to laptop

[silverfoxcc]

I have a desktop PC
To log on i either have to log in via Admin password xxxxxx or user Ron p/w xxxxx

I also have a HP laptop and to log in i just lift the lid and enter a p/w

So far so good

I want to transfer a file from the laptop to the PC and bought a USB-USB link cable thinking i could do the transfer as i normally do with the digital camera

So plugged in both and logged in

No sign of a connection on either computer

Not having a clue on what to do next I tried the network suggestion and it asks me to input my user name and pw

I have tried my PC user name and pw but the laptop doesn't have a user name!

What would be the best way of getting these two to talk to each other

Thanks
