I am having dificulty installing a Micro SATA cable usb 2.0 TTL UART 6pin module serial converter CP2102 and USB to RS232/TTL PL2303HX cable adapter COM module auto converter on a Macbook Pro early 2011 with Yosemite 10.10.3
I ran the following command within the Terminal window
kextstat | grep prolific
148 0 0xffffff7f82bb0000 0x7000 0x7000 com.prolific.driver.PL2303 (1.5.1)
ioreg -c IOSerialBSDClient | grep usb
| | | “IOTTYBaseName” = “usbserial”
| | | “IOCalloutDevice” = “/dev/cu.usbserial”
| | | “IODialinDevice” = “/dev/tty.usbserial”
| | | “IOTTYDevice” = “usbserial”

when I type screen /dev/tty.usbserial 115200 8N1 or screen /dev/tty.SLAB_USBtoUART 115200 8N1Â I just get a blank screen with a blinking prompt. I am not able to type anything, it appears to be hung.
These are the gpio settings that I used. I tried applying the 5v pin and without. When the 5v pin was not connect, I used the regular charger to supply power.
