Hi, 

I try to use USB HSIC port C of sama5d2 to communicate with USB3503 USB HUB. I have enabled ehci layer in device tree and init USB3503 chip with driver. HSIC communication is not enabled (HSIC_EN of UHPHS_INSNREG08 register equal to 0).

I try to force this bit in EHCI driver (there are communication on HSIC but lot of errors protocol error)

Does Atmel EHCI driver supports HSIC communication ? Are there any information about HSIC integration in driver or a patch to apply to kernel ?

Thanks,

Sébastien Corbeau

Good day Sebastien.

 

Any success with this dead post?  I was able to get HSIC up and running talking to a Telit modem.

 

Kind regards
