How do you send the buffer through USB? If you send it in parts, you could update your progress bar every time a part is sent.
If you could share your code it would be easier to make suggestions.

byte[] readBuffer = new byte[2000000];
Filestream dFile = new FileStream(fileName,FileMode.Open,FileAccess.Read);
int read=dFile.Read(readBuffer,0,readBuffer.Length);
USBInterface iface;//selects device interface
iface.OutPipe.Write(readbuffer,0,read);

I send it as a bulk not splitted.
