I bought USB cables on OpenBazaar over a year ago.
As for the updated OpenBazaar, I was trying to use the prebuilt binarys on Linux 64 and Win 64, but many of the directories the binary looks for are dead links.
If anyone got the 64-Bit binarys to work without many file changes, I would be surprised.
I do keep in mind this is just a test release and many bugs are expected.
