The built-in MODE/flag browser doesn't show flag -78, but it is still there. If you saw "USB" in the Port field when checking the APPS dialog, the flag settings are fine. { -33 -78 } CF will clear them both if needed. Likewise, { -33 -78 } FS? will show their current settings. You wouldn't have seen any calc-side activity in the logs if USB hadn't been set.

Seeing the logs you attached, it appears you are using the "unofficial" version of Conn4x which was tweaked by Bill Graves for some timing issues when backing up 48 calculators.

Checking my computer, it appears that I'm using the "official" version 2.3 build 2439. You may want to try that version instead to see if it makes a difference. I was under the impression that the major differences between build 2361 and 2439 pertained to making backups, but there may have been more to it.

This still seems a bit odd to me, though, as the 49g+ and 50g should behave in the same manner if they are both running v2.15 firmware.
