Now that's really strange, but more specific to help pinpoint the issue. What's failing is the transfer of multi-packet data from virtual to real. That's got to be either a timing issue or some kind of bug. The strange part comes from the code being identical for both virtual and real calc, except for the lower-level layer. I know libusb documentation talks about an extra byte sent by Windows but it's supposed to take care of that internally. You presented a specific scenario doing { « 1 1 + 2 2 + 3 3 + 4 4 + » } USBSEND from the virtual calc to the real one. That's something we can try to replicate. Can somebody else confirm this is failing? My calc is dead at the moment (as per the other thread) and until it comes back to life I can't do any testing but perhaps other users can help? Whether it's a 50g, 39g or 40g, the firmware is the exact same code base so if it fails on one it should fail on all of them. |
