USB class support in iMX6

krunalk — Fri, 13 Jan 2017 12:31:47 GMT

Hi,

Does the iMX6ULL support,

1. HID and VCP class in the USB Host mode?

2. HID and VCP class in the USB Device mode?

I am confused because in the " i.MX Linux® Release Notes, Rev. L4.1.15_2.0.0-ga, 10/2016" Page-14, in USB section, they mentioned " USB device mode: MSC, Ethernet, and Serial" only.

Please guide.

Thanks.

Hello Krunal,

The USB driver available in the Linux BSP L4.1.15_2.0.0-ga supports USB Class HID in HOST and Device mode.

Have a great day,
Jaime

Thanks Jamesbone,

Then why they have mentioned only MSC, Ethernet and Serial class in " i.MX Linux® Release Notes, Rev. L4.1.15_2.0.0-ga, 10/2016" Page-14, in USB device section? Is there any limitations?

I am asking because USB HID class is important for me in both USB DEVICE and HOST mode. iMX is a host platform and supports both keyboard, mice so I have no doubt for HID support in Host mode. But I want to make sure that it also supports HID class in device mode.

Thanks again.
