UPDATE: With saleae firmware extracted from 1.0.21 step 3 and following just work. The problem with step 3 and following was clearly related to the (lack of) support for fw 1.1.5.
Just remains the re-enumeration timeout. -- Martin >> Hmm, so it's still not clear to me what the bug really is, but I think >> CMD_GET_FW_VERSION should be retired. biot's use of the usb dscr makes >> much >> more sense. > >>> B: libsigrok version 0574e4c04dac739d758ec609c3737f1a64fea7ac with >>> Saleae 1.1.5 firmware > >>> B: fails first run (with libusb error), works on second run, and fails >>> every following run with "status 2 received 0 bytes".
