Yep. TASCAM US-2X2, but with RealBand 2015. I've been holding off upgrading to 2016 until I can get it sorted in 2015.

TASCAM ASIO driver working will all other applications but otherwise crash on selecting the TASCAM driver. Windows Task Manager the only way out.

TASCAM driver v1.02; Firmware v1.01
Buffer size: 512 samples
Sample Rate: 44.1 kHz

Once RealBand has crashed and subsequently terminated, restarting results in instant crash:
Access violation at address 004A8B02 in module 'RealBand.exe' Read of address 000007FF at: 004A8B02

If I start and minimize BandInABox, RealBand will start although popup declares "Error starting ASIO driver"

Set Audio driver preference to ASIO and choose US-2X2
ASIO "always on" is checked
Preload Track Buffer MS: 2000
Input Ports: US-2X2 In 01 + US-2X2 In 02
Output Ports: US-2X2 Out 01 + US-2X2 Out 02
Buffer size 512 samples
Actual ASIO buffer size in MS: 11.61
Actual ASIO sample rate used: 44100 (Resampler NOT in use)
Click OK,
Popup: "Error installing ASIO driver. If this error persists, reboot Windows."

Well, at least the program doesn't crash.
Choosing MME driver and MS Sound Mapper both Input and Output appears to be the only option that doesn't produce immediate error message. Haven't tested program for functionality yet though.
