There is a known issue on Exynos platforms involving a conflict between older device tree bindings (which predate proper USB device node support) and newer bindings that attach devicetree nodes to USB devices. The kernel includes a workaround that resets the Exynos host controller’s of_node pointer before registering it, to mitigate the side effects of this conflict. If you encounter strange behaviour where USB devices are not correctly enumerated or the driver seems to probe but does not create a usable interface, check whether your kernel includes this workaround.
This is a very common sign of a driver conflict. You might see your device listed as "Exynos USB Device (4.0.0.0)" in Device Manager with a yellow triangle next to it. exynos 3830 usb driver work

For USB 2.0 host mode, the Exynos platform uses standard EHCI (Enhanced Host Controller Interface) and OHCI (Open Host Controller Interface) drivers. These are implemented in ehci-exynos.c and ohci-exynos.c respectively. The EHCI driver is enabled by CONFIG_USB_EHCI_EXYNOS , and the OHCI driver by CONFIG_USB_OHCI_EXYNOS . The kernel configuration help text notes that these drivers support “Samsung S5Pv210 and Exynos SOC's on‑chip EHCI/OHCI controller”. The OHCI driver, in particular, has been part of the mainline kernel since at least 2011, with copyrights held by Samsung Electronics. Download the official Samsung Android USB Driver (v1

For developers working with Samsung’s mid-range mobile SoC, understanding how to configure, enable, and troubleshoot the USB subsystem on an Exynos 3830 platform is a critical but often underestimated part of system bring-up. While the Exynos 3830 itself is not a household name among flagship processors, it is widely used in affordable Galaxy A-series phones and community development boards, making it a practical and cost‑effective target for many projects.
