I'm working on a project which utilizes EZ-USB AN2131. I have a
working driver. Commands are sent to the device in order to operate
it. One command, in particular, causes the flash memory of the device
to be read. This is the sequence:
1) command is sent to device over pipe 2. This is successful.
2) ack is sent from device over pipe 1. The ack is received.
At this point, the flash contents are immediately read over pipe 3,
without anything further being sent to the device. This is
unsuccessful. I have 2 questions:
1) Do USB pipes toggle between one and another on their own? If not,
2) What needs to be done to make them toggle, (in this case from pipe
1 to pipe 3)?
Help is appreciated.
Sincerely,
Mike Krugman
