Dear Maintainer, gspbabel fails to extract data from my DG-100 since I upgraded to the latest testing version 1.5.2-1. The command I use is: gpsbabel -t -i dg-100 -o gpx /dev/ttyUSB0 outputfile3.gpx The command returns an error message: checksum mismatch: data sum is 0x03ba, checksum received is 0x0003 and produces no output. When I downgrade to the stable version (1.5.0-3) without changing any other packages it works correctly. Regards Rod Tye.
