From d0602bd4675c4f49e455b3b7a4aebb9a01287d43 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Thu, 10 Dec 2015 16:56:42 +0300 Subject: [PATCH] axs103: add support of generic OHCI USB 1.1 controller This commit adds support of USB 1.1 storage media on AXS103 board. For some yet unknown reason USB 2.0 doesn't work on AXS103 board issuing messages like this: ------------------------>8------------------- AXS# usb start starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... EHCI timed out on TD - token=0x80008c80 unable to get device descriptor (error=-1) 1 USB Device(s) found ------------------------>8------------------- As a work-around we're falling back to USB 1.1. Indeed it is much slower but at least USB storage devices are usable on AXS103.
