A small README file with installation instructions was added. Now hantekdso automatically searches for models other than DSO-2150. An error was fixed that produced the message, "bfd_check_format: File format is ambiguous," in dsoextractfw on the x64 architecture. An error was fixed that produced the message, "usbfs: process xxxxx (hantekdso) did not claim interface 0 before use," and other improvements were made in the USB code.
