Bus Pirate Support / Problems with I2C binary mode write-read
I'm having problems getting the I2C binary mode write-read command to work. I can successfully communicate with my device using both terminal mode and the simple binary mode commands, but I can't read any data using the write-read command.

Using a logic analyzer I can see that the device address is written and acknowledged, but when reading the Bus Pirate never ACKs any of the incoming bytes. I've tested with a BP3 and a BP4 (both running firmware 6.1), using my own code based on libusbpirate and by entering the commands manually into Hercules. Any suggestions will be greatly appreciated (even a "works for me"), as I've run out of ideas.
