Ticket Name: Regarding USB KEYBOARD/MOUSE/WEBCAM NOT DETECTING on TI J6 Dra7xx board

Query Text:
Hi, Keyboard/MouIse/Webcam are not getting detected on DRA7XX board. I have enabled all the required drivers like USB keyboard driver and USB mouse driver on both kernel and root file system. I have also enabled USB host side drivers in kernel and USB OTG, When I type lsusb , the command returns nothing. When I give lspci, It does not show any USB controller. Request help on this, as I m stuck, Also request to share .config file of kernel, in which USB drivers are working. Thanks n Regards Shalini KP

Hi, Your question has been forwarded to an SW expert. Additionally provide info if you are using custom board or J6 EVM and what is the kernel version. Meanwhile, for more info you can check also below link: processors.wiki.ti.com/.../USB_General_Guide_Linux_v3.8 Best regards Lucy

Thank you for the reply. The issue is sorted after enabling all the USB host side drivers.

Hi What is the release version you are using ? In general each usb port USB1, USB2 is configured to particular mode (host, peripheral, drd/otg), the dr_mode field in usb device tree node need to set appropriately. Please arch/arm/boot/dts/dra7-evm.dts, if the dr_mode for USB1 port is set as "otg", then you need to insert the gadget module. You can insert any gadget like g_zero. (modprobe g_zero). For host only configuration you can force dr_mode property of USBx node to "host" in DT(device tree). Regards Ravi
