Hello,

I am trying to write a driver for an interactive whiteboard.

The device needs to be put into a state that will get it sending the pen data.

However I have been looking examples on the internet and when using
interruptRead or bulkRead you have to specify the number of bytes you are expecting.

There are 30+ commands in the protocol with the device with a length which will
be unknown until I read the first byte.

I want to have a control loop that will read the interrupt and respond to that
data.  With a user interface sending change of state commands.

Does anybody have an example of the use of interruptRead and interruptWrite?

Regards
