When installing any nsp the app freezes and GoldTreePy returns this error:

Traceback (most recent call last):
  File "./Goldtree.py", line 434, in <module>
    sys.exit(main())
  File "./Goldtree.py", line 429, in main

I have tested on USB 2.0 and 3.0 ports. The system is running Linux Mint with Python 3.6 installed.

I can confirm this issue. Seems to happen after Goldleaf asks for 16 MB all at once. Doesn't seem to be a problem for smaller (homebrew) NSPs though

This seems to be an issue with libusb vs libusbK. libusb seems to not handle the large transfer the same way libusbK does, no idea why they are different.

gudenau commented

Looks like a working fix is to split the transfers into smaller chunks, the client handles it correctly.

friedkeenan commented

Hmm, I'll mess with that soon then. Thanks

friedkeenan commented

Latest commit should install NSPs as well as Goldtree can (I ran into a bug but it was reproducible on Goldtree). Writing big files is still a problem, and reading data in chunks didn't work like writing data in chunks does, but I guess this issue can be closed.

Great! What about making a new release?
BTW, thanks a lot for this tool!

I'm waiting to make a new release just in case XorTroll changes the USB stuff in the near future. We'll see.
