[QUOTE="krs, post: 1853273, member: 67742"] Jake, What you quoted was a comment about converting existing product designs to USB-C, not about a USB 2 to USB-C adapter which is what I was wondering about. A USB 2 to USB-C adapter will only be able to provide the capability of USB 2.0 (speed and power) but now allows the USB 2.0 device to be plugged into a USB-C port, that is conceptually the same as the capability of plugging a USB 1 keyboard into a USB 2.0 port, it works without problems but one only gets USB 1 speeds and power not USB 2 speeds. Same applies plugging a USB 1 or USB 2 device into a USB 3 port, again one only gets the USB 1 or USB 2 capabilities of the device that is connected. Same for USB 2.0 to USB-C adapter. The most electronics for such an adapter are some pull-up resistors. So I'm still wondering where the "convert" Usb 2.0 to USB-C comes from. The only 'conversion', if one can even call it that, is the physical shape of the connector and the pin assignment. And that is reflected in the price Apple charges for a USB 2 to USB-C cable. Going back to Lisa's post #8, it would be interesting to find out what is so different with the USB-C port on the Caldigit device. [/QUOTE]
