Putting the dib7000p device in and out of sleep can trigger a race,
|
||
|
|
causing the usb device to stall (-EPIPE), resulting in i2c errors:
|
||
|
|
|
||
|
|
DiB0070 I2C write failed
|
||
|
|
DiB0070 I2C read failed
|
||
|
|
|
||
|
|
As a workaround, do not put the device to sleep
|
||
|
|
|
||
|
|
Perhaps the dib8000/9000 need the same workaround
