Hi all,
I have a problem with 18f4550. I use pic basic pro and when I send information from pc, I want to show this info on 16-segments. But, in my experiences, if usb module is active, I can't use 16-segments ( I use 8 of 16-segment) In short, I have to save this incoming info at EEPROM, but again, if USB Module is active, it don't save on EEPROM :s ( I use "write")

My question is, how can I disable USB (to make save) or how can I make save when USB is active

please help me, this is my school project and I have to do this. I can transfer data by Visual basic and use it on 8 of leds, but I have to do it with 16-segment display.

Thanks

NOTE: I'm using Proteus 7.4 simulation, I don't know if a real 18f4550 can save while USB active.
