Can't Switch From Class 2 to Class 1 Mode
Issue:
This indicates the BLU link bus sample rate has
been changed from 96kHz to 48kHz but the BLU-USB did
not detect the change and is still operating at a 96kHz
sample rate, which Class 1 mode does not support.
Resolution:
Power cycle the BLU-USB. This will force the
BLU-USB to re-scan the BLU link bus and re-configure
its sample rate accordingly. Note that other auto-sensing BLU link devices may
also require a power cycle for the same reason.

Solid Red when Pressing the MODE Pushbutton
Issue:
This indicates the BLU link bus is operating at a
96kHz sample rate, and the BLU-USB cannot be switched
to Class 1 mode because that mode does not support
96kHz.
Resolution:
Change the master BLU link device to operate
at a 48kHz BLU link bus sample rate. All BLU link devices
which require manual sample rate configuration must also be re-programmed
to match.
Once the manually-configured BLU link devices have been re-configured, any
auto-sensing BLU link devices that have not automatically updated to the new
sample rate, including the BLU-USB, should be power cycled so they can detect
the new BLU link sample rate and re-configure themselves accordingly.

Issue:
This indicates the BLU link bus is operating at a
96kHz sample rate and the BLU-USB is set to Class 1
mode, which does not support a 96kHz sample rate.
Resolution:
Either switch the BLU link sample rate to
48kHz in the master BLU link device (then power cycle the
BLU-USB if the problem persists) or switch the BLU-USB
to Class 2 mode (see
'Selecting the USB Mode' on page 11
for instructions on
switching modes).
NOTE:
If you just changed the BLU link sample rate from 96kHz to 48kHz, make
sure to wait for the BLU-USB to detect the change before trying to switch to
Class 1 mode. If it still won't change, try power cycling the BLU-USB to force it
to re-detect the new BLU link sample rate.
