target is not in the device-reported DPI list ( )

Error message

target {target} is not in the device-reported DPI list ({})

What it means

Input validation in `openlogi diag dpi`: the --target DPI value passed by the user is rejected because it is not among the DPI values the device itself reports through its HID++ AdjustableDpi/ExtendedAdjustableDpi feature. Only device-advertised values are valid write targets, and the message includes the full supported list (or a range summary) so the user can pick a valid one. This is a pre-write guard, not a hardware failure.

Solutions

1. Re-run with a --target value taken from the printed supported DPI list, e.g. --target 1600
2. Omit --target entirely and let the diagnostic pick an adjacent supported value automatically
3. If the intended value seems like it should be supported, confirm the device's actual capability list — some firmware advertises only a sparse set of steps
