> I own several devices that won’t work with a C-to-C cable. Somehow something gets confused. You need to use a C-to-A cable These devices are probably missing the resistors between each of the two CC pins and the ground, which are necessary to tell the computer on the other end of the C-to-C cable "I'm a device and need you to put 5V on the power pins". The C-to-A cable, on the other hand, always has that 5V power (because the A end of the connection always supplies power; that's the reason why A-to-A cables are forbidden, they would short together the power supply of both ends), which means the device gets powered even if it's missing the CC resistors. That is, it's a manufacturing defect, and the device was probably tested only with C-to-A cables; once C-to-C cables become more common (at least where I live, it took a long time before I managed to even find one, while C-to-A cables were plentiful and many devices came with one), this will become less of a problem.
