Mike,

Great!  Thank you for the answers.

If you would indulge one more (compound) question:

Looking at the I2C master implementation in pvrusb2, it looks like it
would be OK for me to combine the i2c_master_write() and
i2c_master_read() in cx25840_read() into a single 2 "msg" i2c_transfer()
without the pvrusb2 driver having a problem.

a. Is that correct?
b. Is there a limit on the combined payload, such that a the
cx25840_read4() would not work as a combined i2c_transfer() ?

Regards,
Andy
