Hi, I have a CM4 Dual Gigabit carrier board for prototyping. On this board, am I able to use the USB 2.0 bus at “normal” runtime (i.e. without the boot jumper) if I use a USB-OTG cable to supply power and break out an A plug? For this particular application I need to keep the communications to/from USB2 and USB3 separate with the respective device types on their designated bus.
Hello @johnpdowling,
Could you please provide me with a rough diagram regarding the connections you are asking for, so that it will be more clear for me?
Also, you want the USB 2.0 (Type-C) in USB Host Mode or USB Device Mode?
Thank you.
Best Regards,
Lakshantha
Host mode, I believe. Sorry if the ASCII art doesn’t work:
Power ->
____Pi USBC2.0
/
USBA2.0<-/
The end goal being to power up, boot via emmc, and have access to USB2.0 devices on the USB2.0 bus. We’re already fine with accessing 3.0 devices on the 3.0 A ports.
Unfortunately, you cannot use the USB 2.0 (Type-C) in HOST Mode. It can only act in device mode.
