Spider27 Posted May 22, 2023 Posted May 22, 2023 Hello. Does anyone know how to use this USB cable to split between signal and power? I guess that USB A male to USB B male is for purely signal transfer and the USB B female at the back is to feed 5v USB power? If anyone used this type of USB cable before, please enlighten me. Thank you...
mikescraigslist Posted May 22, 2023 Posted May 22, 2023 I think you got it the other way around. Male A is used to supply power to male B via the power pins, and you get signal out from female B through another cable. I'm assuming power lines between male and female B had been cut so there is isolation. 1

I am trying to connect Topping D10 which takes both signal and power from desktop/laptop via USB and I am thinking to split the signal and power and feed the power from 5v linear power supply. Have I understood correctly that USB A male is to be connected to Desktop since desktop does not take USB B type and signal travel from USB A to USB B Male. USB B Male has signal and power pin separated so LPS is connected to the back of female USB B socket and the male USB B is now carries both signal and power and is to be connected to Topping D10 USB socket.
mikescraigslist Posted May 22, 2023 Posted May 22, 2023 (edited) No I think you plug male B into the D10 and male A into your power source. Like a phone charger or similar. You connect desktop to D10 via a typical male B to male A cable. Call this the printer cable. The printer cable will normally also carry power from desktop to D10, but not in this case because power lines between the female and male B (on the cable in the photo) are cut. In this photo cable, male A supply power to male B so your printer cable's power is unused. Edited May 22, 2023 by mikescraigslist 1
