Hello, Brian!

My modem has two modes: one with pseudo-ethernet, and the second without
it. I think, this config for usb_modeswitch should work for you:

########################################################
# ZTE MF192 (PPP and pseudo-ethernet interfaces)

DefaultVendor= 0x19d2
DefaultProduct=0x1517

MessageContent="555342430800498200000000000010FF000000000000000000000000000000"


Can you try it, and let me know, if it works?
