Hi, I'm trying to use the BV4205 with a raspberry pi Model B revision 2.0 and so far I have managed to detect the device only one time. (and by using the ./i2c_slow version of the bcmdel fix) I don't know if revision 2.0 is the cause of the problem. The main difference with revision 1.0 regarding i2c bus is the change of the pins of i2c-0 with those of i2c-1. So, I'm still using pins 3 andby nicktgr15 - Serial & I2C Devices
