USB Drivers for LPC2478

 USB Drivers for LPC2478

Hai this is Siva Krishna,
I am present implementing USB Pendrive drivers on LPC2478.
Here USB Pendrive is a slave that means device,so arm will act as host.Am i correct?

If it is correct how to initalize the HOST in LPC2478?
or it it wrong what is the correct process for implementing USB drivers on LPC2478.

Thanks & Regards
Siva Krishna

 arm will act as host.Am i correct?

Yes - the ARM will need to act as the Host.

"how to initalize the HOST in LPC2478?"

By following the instructions in the Datasheet, and/or User Manual, and any other supporting documentation provided by the manufacturer, tool vendor, etc.

"what is the correct process"

Standard process for interfacing anything to anything else: http://www.8052.com/forum/read/160143
