Must use "Pro Mk3" name to open connection to Launchpad Pro Mk3 on Raspberry Pi OS Buster #69
Description
As a heads up, you must include the "Pro Mk3" name when checking or opening the Launchpad Pro Mk3 on Raspberry Pi OS Buster. This is with the default installation of Python 3.7.3 and Pygame 1.9.4 and using local launchpad.py (current 0.9.1). It's a fresh installation with nothing but an apt update && upgrade run.
Using the default check and open methods (such as in the hello.py example), the Launchpad is recognized only as a Pro and not a Pro Mk3. This results in no LED methods functioning properly, but button events fire properly with pressure.
This is the output from information.py:

Output from various methods:
print( launchpad.LaunchpadProMk3().Check( 0 ) ) #False
print( launchpad.LaunchpadPro().Check( 0 ) ) #True
print( launchpad.Launchpad().Check( 0 ) ) #True
print( launchpad.LaunchpadProMk3().Check( 0, "Pro Mk3") ) #True
lp = launchpad.LaunchpadProMk3()
print( lp.Check() ) #False
print( lp.Open() ) #False
print( lp.Check( 0 , "Pro Mk3" ) ) #True
print( lp.Open( 0, "Pro Mk3" ) ) #True
Using the Open(0, "Pro Mk3") does seem to work and my initial testing hasn't found any issues. I'll update if I come across anything.
